Area Forecast Discussion
National Weather Service Taunton MA
644 AM EDT SAT JUN 25 2016

.SYNOPSIS...
Large high pressure ridge extending across the northeast U.S.
into the Gulf of Maine will slowly shift down the coast, with
warm and dry conditions through Monday. An approaching cold
front brings showers and possibly some thunder later Monday
night through Wednesday. High pressure then brings dry
seasonable weather for the end of next week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

645 AM update

High pressure overhead with generally clear skies and light wind.
Dew points are 45 to 55. This is lower/drier than the long-term
average for June 25th of 55 to 58, but still much higher than the
extreme low values for June 25th of 33 to 36.

This is your all-purpose fair weather day with the light flow
allowing sea breezes along the coasts. No changes to the forecast.

Previous discussion

W-E high pressure ridge axis sitting from W NY state to the Gulf
of Maine will slowly shift to the S coast during the day today.
Expect a generally light E-SE wind, becoming more southerly across
N CT and the CT valley this afternoon. With a light pressure
gradient, sea breezes will kick in by midday with speeds up to
around 10 kt.

With a very dry airmass in place through the layer, expect excellent
subsidence through the day even with fair lapse rates as H5 temps of
-14C to -15C. Do note some afternoon showers trying to develop, but
mainly across the Hudson Valley into the northern mountains of
NH/VT as winds become more S there.

Expect temps to rise to the 80s away from the coast, highest across
the CT valley where a 90 degree reading may be possible, while
holding in the 70s along the immediate coast.  It will feel
comfortable though as dewpts remain in the lower-mid 50s.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
Tonight...

With high pressure ridge across the region, will continue to be
dry and comfortable as dewpts fall back to the upper 40s to mid
50s. Light/variable winds in place, dropping off to calm across
some inland areas. With continued good radiational cooling, will
see temps fall back to the upper 40s to around 50 in the normally
prone areas of interior E Mass to the lower Cape and the Vineyard,
ranging to the mid 50s to around 60 in the urban centers. Once
again, may see a few hours of patchy low clouds and fog around or
after 06Z in the typically prone locations.

Sunday...

As the ridge begins to push S of the region, light winds will
become more S-SE across the region. While dry conditions continue
with dewpts in the lower-mid 50s, will start to see them creep up
during the afternoon across the CT valley. Expect another warm day
with highs in the 80s away from the coast, and in the lower-mid
70s near the shore.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Big Picture...

A shortwave originating over the Pacific Northwest moves east across
Canada and then digs over New England Tuesday and Wednesday. Above
normal heights Monday diminish to near normal the rest of the week.
This suggests above normal temps Monday trending to normal during
mid to late week.

Model forecast mass fields are similar much of the period. There are
differences between GFS and ECMWF with timing on the midweek cold
front. Confidence is limited as to exact timing, but potential for
convection should exist for both days.

Details...

Sunday night through Monday...

High pressure offshore moves farther away, and the surface flow
turns more from the south and southwest. Expect dry weather during
this time. 850 mb temps of 14-16C would support max sfc temps in the
mid 80s.

Monday night through Wednesday...

Northern shortwave approaches from the Great Lakes. At this time the
upper shortwave digs southeast toward New England and turns the
upper flow more from the southwest and parallel to the cold front.
With flow moving along the cold front rather than pushing it, we
should see the forward progress slow until the trough axis swings
overhead. Meanwhile the surface flow will bring a warm humid airmass
across New England with dew points climbing into the 60s. Stability
parameters will favor convection. The cold front will be the
eventual focusing mechanism on Wednesday, but a pre-frontal
trough may concentrate convection on Tuesday.

Thursday-Friday...

High pressure builds in behind the cold front but with upper
contours and 850 temps near seasonal normals.

Area Forecast Discussion...UPDATED
National Weather Service Gray ME
620 AM EDT SAT JUN 25 2016

.SYNOPSIS...
High pressure remains in control over the weekend before moving
offshore later in the the weekend and early next week. This will
allow a more humid air mass to move into the region. A slow
moving cold front approaching from the west brings a chance of
showers and thunderstorms Tuesday, Wednesday and into early
Thursday. The front will exit the region by late Thursday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
620 AM Update...
A few cirrus clouds are crossing the area this morning. That as
well as some spots of fog in the CT river valley is about all that
is going on this morning. Temperatures are in the 40s and 50s and
will warm up into the 70s and 80s today.


Previous Discussion...
High pressure remains in control at the surface and aloft
delivering another beautiful sunny and mostly-cloud-free day. By
midday dew points will be about 10 degrees higher than they were
24 hours ago indicating southerly winds are transporting moisture-
rich air into the area. There is a small chance of showers mainly
over the North Conway/Mt Washington environ as a short wave passes
by overhead. Temperatures will reach the upper 70s to mid 80s with
warmer temperatures even reaching the mountains today. A sea
breeze will keep temperatures along the coast just a few degrees
cooler.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
Tonight readings will drop into the 50s areawide under light winds
and mostly clear skies. This will allow for fog to form in valleys
and other favored region similar to previous nights. We are
expecting an even warmer day Sunday with mid to upper 80s in quite
a few locations. Once again high pressure off shore will produce
conditions ripe for a sea breeze which will penetrate inland a
ways and keep highs a bit cooler along the coast.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
A warm south to southwest flow will continue Sun night into Tue
ahead of an approaching trough and associated surface cold front.
Temperatures will continue mild and become humid ahead of the
system. By Mon night showers and thunderstorms will begin to move
across the area ahead of the system. The surface cold frontal
passage will occur late Tue or Tue night. On Tue and Tue night
showers and thunderstorms are expected bringing some much needed
rain. The front moves off the coast by early Wed but a lingering
upper trough will produce some lingering showers Wed into Thu.
By late Thu and Fri a return to dry and relatively mild weather
can be expected as high pressure builds east. Generally accepted
the superblend guidance for this outlook period.

&&

.AVIATION /10Z SATURDAY THROUGH WEDNESDAY/...
Short Term...VFR conditions through Sunday will prevail. However
patchy MVFR restrictions in valley fog are possible late tonight
and again Sunday night, mainly at LEB and HIE. A sea breeze is
likely Saturday and Sunday afternoons.

Long Term...VFR through Monday. MVFR to IFR conditions in
showers/thunderstorms Mon night into Wed.

&&

.MARINE...
Short Term...Relatively tranquil waters with winds and seas below
small craft criteria are forecast through SUnday.

Long Term...winds and seas to remain below sca levels through the
period.

356 AM EDT SAT JUN 25 2016

.SYNOPSIS...
Large high pressure remains over the northeast U.S. into early
next week keeping warm and dry conditions across the region.
Warmest days will be Sunday afternoon into Monday with highest
temperatures inland. An approaching cold front brings showers and
psoobly some thunder later Monday night through Wednesday. High
pressure then brings dry seasonable weather for the end of next
week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
1045 PM Update...

Mainly clear skies across the region at 02Z. Noting a few mid
level clouds moving across near the E slopes of the Berkshires of
NW Mass, along with some mid and high clouds scrapping across the
islands from the northern fringe of scattered showers and a few
thunderstorms moving E at around 40N southward.

With high pressure across the region and winds dropping off to
near calm, temps will continue to fall back especially in the
normally cooler valley. Seeing temps down to the mid 50s across
interior E Mass and even at Martha`s Vineyard with calm winds.
Could see patchy radiation fog developing in those areas after 1
or 2 AM through around sunrise. Otherwise, expect clear
conditions overnight for most of the area.

Near term forecast pretty much on track. Have updated to bring
conditions current and incorporated into the overnight trends.

Previous discussion...

With the ideal radiational cooling conditions followed the cooler
MET and MAV guidance as 2m temps too warm in this pattern for
overnight mins.

Could be a few hours of patchy fog toward daybreak in the
typically prone locations.

Could be some mid to high cloudiness on the southern horizon
across the Islands and Cape Cod as shortwave energy in the WNW
flow aloft induces a weak frontal wave off the mid-Atlantic coast
and tracks eastward, south of 40N.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/...
Saturday...

High pressure overhead providing light winds and promoting
afternoon sea breezes. However, with mean mid-level trough axis
just offshore, cold temps aloft linger across southern New
England with H5 temps about -14C. This provides modest mid level
lapse rates, however should be enough deep layer dry air within
the column to offset any shower potential. NAM offers a risk of
isolated afternoon showers in the high terrain however this is a
result of its dew pts climbing into the 60s. Not happening with
surface ridge over the area and other model guidance limiting dew
pts to the 50s. Thus have discounted the NAM and will continue
with a dry forecast.

Very similar day tomorrow to today with comfortable humidity and
warm temps with afternoon highs in the 80s inland away from the
cooling afternoon sea breezes. Highs in the 70s along the coast.
Given the recent dry weather /dry soil, etc/ temps have been
overachieving. Thus have added a few degs to a model blend.

Sat night...

High pressure remains over the area providing dry weather. Another
comfortable cool night with low dew pts, light winds and mostly
clear skies. Followed a blend of the MOS guid which yielded lows
in the 50s to near 60 in the city of Boston. Could be a few hours
of patchy fog toward daybreak in the typical prone locations.

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...

Big Picture...

A shortwave originating over the Pacific Northwest moves east across

320 AM EDT SAT JUN 25 2016

.SYNOPSIS...
High pressure remains in control over the weekend before moving
offshore later in the the weekend and early next week. This will
allow a more humid air mass to move into the region. A slow
moving cold front approaching from the west brings a chance of
showers and thunderstorms Tuesday, Wednesday and into early
Thursday. The front will exit the region by late Thursday.

&&

.NEAR TERM /THROUGH TODAY/...
High pressure remains in control at the surface and aloft
delivering another beautiful sunny and mostly-cloud-free day. By
midday dew points will be about 10 degrees higher than they were
24 hours ago indicating southerly winds are tranporting moisture-
rich air into the area. There is a small chance of showers mainly
over the North Conway/Mt Washington environ as a short wave
passes by overhead. Temperatures will reach the upper 70s to mid
80s with warmer temperatures even reaching the mountains today. A
sea breeze will keep temperatures along the coast just a few
degrees cooler.

&&

.SHORT TERM /TONIGHT THROUGH 6 PM SUNDAY/...
Tonight readings will drop into the 50s areawide under light winds
and mostly clear skies. This will allow for fog to form in valleys
and other favored region similar to previous nights. We are
expecting an even warmer day Sunday with mid to upper 80s in quite
a few locations. Once again high pressure off shore will produce
conditions ripe for a sea breeze which will penetrate inland a
ways and keep highs a bit cooler along the coast.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
A warm south to southwest flow will continue Sun night into Tue
ahead of an approaching trough and associated surface cold front.
Temperatures will continue mild and become humid ahead of the
system. By Mon night showers and thunderstorms will begin to move
across the area ahead of the system. The surface cold frontal
passage will occur late Tue or Tue night. On Tue and Tue night
showers and thunderstorms are expected bringing some much needed
rain. The front moves off the coast by early Wed but a lingering
upper trough will produce some lingering showers Wed into Thu.
By late Thu and Fri a return to dry and relatively mild weather
can be expected as high pressure builds east. Generally accepted
the superblend guidance for this outlook period.

&&

.AVIATION /07Z SATURDAY THROUGH WEDNESDAY/...
Short Term...VFR conditions through Sunday will prevail. However
patchy MVFR restrictions in valley fog are possible late tonight
and again Sunday night, mainly at LEB and HIE. A sea breeze is
likely Saturday and Sunday afternoons.

Long Term...VFR through Monday. MVFR to IFR conditions in
showers/thunderstorms Mon night into Wed.

.SYNOPSIS...
High pressure strengthens over northern New England from the
northwest tonight and remains into Saturday. This high will move
offshore later in the the weekend and early next week and allow a
more humid air mass to move into the region. A slow moving cold
front approaching from the west brings a chance of showers and
thunderstorms Tuesday, Wednesday and into early Thursday. The
front will exit the region by late Thursday.

&&

.NEAR TERM /UNTIL 6 AM THIS MORNING/...
1215 AM Update...
Minor changes to the forecast for temperatures...sky...and wind.
Forecast looks on track at this point with a good night of
radiational cooling ahead of us.


Previous discussion...
High pressure will remain over the region tonight. This will mean
clear to mostly clear skies. Winds will be light and will allow
for a cool-ish night as radiational cooling should occur. Valley
fog is once again possible late tonight in the CT valley.

&&

.SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SUNDAY/...
Saturday should be a warmer day and mostly dry. With a little more
moisture in the low levels working in tandem with cold temps aloft
there could be a few showers or thunderstorms in the mountains
during the afternoon hours with the help of orographics. The rest
of the region should be mostly sunny.

Mostly clear night on tap for Saturday night with some valley fog
once again possible.

&&

.LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/...
Drought conditions persist across the forecast area as the region
awaits a soaking rain. It will remain dry Sunday as upper level
ridging continues over Maine and New Hampshire. It will be mild
inland at H8 temperatures reach ~ +15C. Along the coast, sea
breezes will continue to keep chilly conditions with highs only in
the 70s. Similar conditions can be expected on Monday as a very
slow cold front approaches from the northwest.

By Tuesday, an upper level low pressure system and surface cold
front will continue to slowly move east. Moisture will be
entrained into the system as a southerly flow develops ahead of
the system. Showers will break out into the mountains late in the
day.

The upper level feature and frontal system will become stationary
as we head into Wednesday allowing more showers over far western
portions of the forecast area. Some of this precipitation may be
heavy due to the slow movement of the system and increasing
precipitable water values.

The system will begin to lift out of the region on Thursday as
another upper level feature builds into the region from Hudson`s
Bay Canada.

&&

.AVIATION /04Z SATURDAY THROUGH WEDNESDAY/...
Short Term...VFR conditions through Saturday night will prevail.
However patchy MVFR restrictions valley fog are possible late

.SYNOPSIS...
Large high pressure remains over the northeast U.S. into early
next week keeping warm and dry conditions across the region.
Warmest days will be Sunday afternoon into Monday with highest
temperatures inland. A frontal boundary may bring showers and
thunderstorms to the area Tuesday and Wednesday. More seasonable
weather is expected late in the week.

&&

.NEAR TERM /UNTIL 6 AM SATURDAY MORNING/...

1045 PM Update...

Mainly clear skies across the region at 02Z. Noting a few mid
level clouds moving across near the E slopes of the Berkshires of
NW Mass, along with some mid and high clouds scrapping across the
islands from the northern fringe of scattered showers and a few
thunderstorms moving E at around 40N southward.

With high pressure across the region and winds dropping off to
near calm, temps will continue to fall back especially in the
normally cooler valley. Seeing temps down to the mid 50s across
interior E Mass and even at Martha`s Vineyard with calm winds.
Could see patchy radiation fog developing in those areas after 1
or 2 AM through around sunrise. Otherwise, expect clear
conditions overnight for most of the area.

Near term forecast pretty much on track. Have updated to bring
conditions current and incorporated into the overnight trends.

Previous discussion...

With the ideal radiational cooling conditions followed the cooler
MET and MAV guidance as 2m temps too warm in this pattern for
overnight mins.

Could be a few hours of patchy fog toward daybreak in the
typically prone locations.

Could be some mid to high cloudiness on the southern horizon
across the Islands and Cape Cod as shortwave energy in the WNW
flow aloft induces a weak frontal wave off the mid-Atlantic coast
and tracks eastward, south of 40N.

&&

.SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/...

Saturday...

High pressure overhead providing light winds and promoting
afternoon sea breezes. However, with mean mid-level trough axis
just offshore, cold temps aloft linger across southern New
England with H5 temps about -14C. This provides modest mid level
lapse rates, however should be enough deep layer dry air within
the column to offset any shower potential. NAM offers a risk of
isolated afternoon showers in the high terrain however this is a
result of its dew pts climbing into the 60s. Not happening with
surface ridge over the area and other model guidance limiting dew
pts to the 50s. Thus have discounted the NAM and will continue
with a dry forecast.

Very similar day tomorrow to today with comfortable humidity and
warm temps with afternoon highs in the 80s inland away from the
cooling afternoon sea breezes. Highs in the 70s along the coast.
Given the recent dry weather /dry soil, etc/ temps have been
overachieving. Thus have added a few degs to a model blend.

Sat night...

High pressure remains over the area providing dry weather. Another
comfortable cool night with low dew pts, light winds and mostly
clear skies. Followed a blend of the MOS guid which yielded lows
in the 50s to near 60 in the city of Boston. Could be a few hours
of patchy fog toward daybreak in the typical prone locations.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Highlights...

* Warm temperatures Sunday and Monday
* Showers and thunderstorms possible Tue into Tue night
* Cooler and drier weather returns late Wednesday or Thursday

Overview...Models are in overall good agreement on the long term
portion of the forecast.  Will use a blend of available guidance for
this forecast.  Relatively quiet pattern continues with broad upper
level ridge over the western U.S. and broad upper troughing over the
eastern U.S.  A cold front will move through southern New England on
Tuesday or Wednesday (depending on the model, GFS is faster)
bringing showers and thunderstorms to the area.

Temperatures...A warming trend is expected Sunday and Monday with
temperatures climbing well into the 80s and possibly into the 90s in
the Connecticut Valley Monday.  Slightly cooler temperatures Tuesday
and Wednesday as a cold front moves through.  Temperatures return to
seasonable levels for the end of the week.

Precipitation...There is a chance of showers Tuesday and possibly
into Wednesday as a cold front moves through southern New England.
There is enough instability indicated in the models for some thunder
with these showers.  Plenty of uncertainty here as dry weather tends
to lead to more dry weather.  Not looking at any significant
precipitation through the end of next week.

comfortable cool night with low dew pts...light winds and mostly
clear skies. Followed a blend of the MOS guid which yielded lows
in the 50s to near 60 in the city of Boston. Could be a few hours
of patchy fog toward daybreak in the typical prone locations.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Highlights...

* Warm temperatures Sunday and Monday
* Showers and thunderstorms possible Tue into Tue night
* Cooler and drier weather returns late Wednesday or Thursday

Overview...Models are in overall good agreement on the long term
portion of the forecast.  Will use a blend of available guidance for
this forecast.  Relatively quiet pattern continues with broad upper
level ridge over the western U.S. and broad upper troughing over the
eastern U.S.  A cold front will move through southern New England on
Tuesday or Wednesday (depending on the model, GFS is faster)
bringing showers and thunderstorms to the area.

Temperatures...A warming trend is expected Sunday and Monday with
temperatures climbing well into the 80s and possibly into the 90s in
the Connecticut Valley Monday.  Slightly cooler temperatures Tuesday
and Wednesday as a cold front moves through.  Temperatures return to
seasonable levels for the end of the week.

Precipitation...There is a chance of showers Tuesday and possibly
into Wednesday as a cold front moves through southern New England.
There is enough instability indicated in the models for some thunder
with these showers.  Plenty of uncertainty here as dry weather tends
to lead to more dry weather.  Not looking at any significant
precipitation through the end of next week.

.SYNOPSIS...
Large high pressure remains over the northeast U.S. into early
next week keeping dry conditions across the region. Warm days and
cool nights will continue into Sunday morning...then turning hot
beginning Sunday afternoon into Monday with highest temperatures
inland. A frontal boundary may bring showers and thunderstorms to
the area Tuesday and Wednesday. More seasonable weather is
expected late in the week.

This evening...

Weak high pressure over the region and accompanied by a dry
airmass with dew pts in the 40s inland...50s along the coast is
providing splendid weather by late June standards. Dry column
only yielding some scattered strato-cu with a focus for the clouds
across CT into RI as seabreeze moving inland provides some
convergence. Also some additional diurnal clouds over the higher
terrain but nevertheless mostly sunny skies.

Given the dry airmass with dew pts in the 40s temps will fall
noticeably with sunset given mostly clear skies and light winds.
Diurnal clouds will also erode with sunset as well. Other than
cooling temps with sunset a very pleasant evening ahead.

Overnight...

Another comfortable night with lows in the 50s regionwide except
around 60 in the city of Boston. Given the ideal radiational
cooling conditions followed by cooler MET and MAV guidance as 2m
temps too warm in this pattern for overnight mins.

Could be a few hours of patchy fog toward daybreak in the typical
prone locations.

Could be some mid to high cloudiness on the southern horizon across
the Islands and Cape Cod as short wave energy in the WNW flow
aloft induces a weak frontal wave off the Mid Atlc coast and
traces eastward...south of 40N.

High pressure overhead providing light winds and promoting
afternoon seabreezes. However with mean mid level trough axis just

however should be enough deep layer dry air within the column to
offset any shower potential. NAM offers a risk of isolated
afternoon showers high terrain however this is a result of it`s
dew pts climbing into the 60s. Not happening with surface ridge
over the area and other model guidance limit dew pts to the 50s.
Thus have discounted the NAM and will continue with a dry
forecast.

Very similar day tomorrow to today with comfortable humidity and
warm temps with afternoon highs in the 80s inland away from the

Big Picture...

Longwave pattern continues to show ridge west/trough east through
next week. Shortwave scale shows a ridge over New England Sunday
moving east of us on Monday. A shortwave originating over the
Pacific Northwest moves east across Canada over the weekend and
then digs over New England Tuesday and Wednesday.

Above normal heights with the ridge Sunday-Monday, diminishing to
near normal Tuesday-Wednesday. This suggests above normal temps
Sunday-Monday returning to near normal midweek.

Model forecast mass fields are similar through Monday, then
diverge a little starting Tuesday. Even with the divergence, the
forecast scenarios are similar. This encourages confidence in the
forecast through midweek.

Details...

Saturday night through Monday...

High pressure in control with dry weather. Light flow on Sunday
will support sea breezes along the coasts which will buffer
daytime max temps in those areas while the interior heats up. The
top of the mixed layer Sunday and Monday will be between 800 mb
and 850 mb, with temps supporting max surface temps 85 to 90.
Model temps for Monday actually looked a few degrees too cool.
Suspect sunshine will allow for deeper mixing and warmer temps. We
bumped values up 3 degrees F.

Monday night through Thursday...

Northern shortwave pushes a cold front through the Great Lakes
early week and across New England Tuesday or Wednesday. The GFS
shows the faster timing with passage on Tuesday, while the ECMWF
is slower with cold fropa Wednesday. As the shortwave digs over
the Northeast USA the upper flow turns more southwest and parallel
to the front. This would work to slow down forward progress until
the shortwave axis sweeps through. Thus we favor the slower EC
scenario, but with enough uncertainty to mention chance pops later
Monday night and Tuesday. Stability parameters show potential for
thunder.

Weak high pressure builds dry weather in for Thursday.

.SYNOPSIS...
High pressure strengthens over northern New England from the
northwest tonight and remains into Saturday. This high will move
offshore later in the the weekend and early next week and allow a
more humid air mass to move into the region. A slow moving cold
front approaching from the west brings a chance of showers and
thunderstorms Tuesday, Wednesday and into early Thursday. The
front will exit the region by late Thursday.

&&

.NEAR TERM /THROUGH TONIGHT/...
High pressure will remain over the region tonight. This will mean
clear to mostly clear skies. Winds will be light and will allow
for a cool-ish night as radiational cooling should occur. Valley
fog is once again possible late tonight in the CT valley.

&&

.SHORT TERM /SATURDAY THROUGH SATURDAY NIGHT/...
Saturday should be a warmer day and mostly dry. With a little more
moisture in the low levels working in tandem with cold temps aloft
there could be a few showers or thunderstorms in the mountains
during the afternoon hours with the help of orographics. The rest
of the region should be mostly sunny.

Mostly clear night on tap for Saturday night with some valley fog
once again possible.

&&

.LONG TERM /SUNDAY THROUGH FRIDAY/...
Drought conditions persist across the forecast area as the region
awaits a soaking rain. It will remain dry Sunday as upper level
ridging continues over Maine and New Hampshire. It will be mild
inland at H8 temperatures reach ~ +15C. Along the coast, sea
breezes will continue to keep chilly conditions with highs only in
the 70s. Similar conditions can be expected on Monday as a very
slow cold front approaches from the northwest.

By Tuesday, an upper level low pressure system and surface cold
front will continue to slowly move east. Moisture will be
entrained into the system as a southerly flow develops ahead of
the system. Showers will break out into the mountains late in the
day.

The upper level feature and frontal system will become stationary
as we head into Wednesday allowing more showers over far western
portions of the forecast area. Some of this precipitation may be
heavy due to the slow movement of the system and increasing
precipitable water values.

The system will begin to lift out of the region on Thursday as
another upper level feature builds into the region from Hudson`s
Bay Canada.

showers and thunderstorms possible Tuesday. More seasonable
weather is expected late in the week.

7 am update

Patches of fog in SE Mass and Ct Valley are burning off. Generally
fair skies over the region, and the fair weather will continue
through the day.  No changes planned for the forecast.

Previous discussion

High pressure ridge stretching from the Great Lakes into northern
New England early this morning will slowly shift into the region
this afternoon. With the position of this high, expect N-NE winds
to veer to E-NE during the day but, with a low pressure gradient
in place, winds will generally be at 10 mph or less. Will see some
gusts up to around 15 mph this morning along the immediate S coast
and the islands.

H85 temps start off in the +9C to +12C range this morning, but
should recover to +12C to +14 during the afternoon. With nearly
full summer sunshine, expect temps to recover to the mid 70s to
lower 80s away from the coast, but will remain cooler especially
along the E coast with the onshore winds.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
Tonight...

As the ridge axis slowly settles across the region, it will
gradually shift E. Expect mainly clear conditions with light E-SE
winds. Will need to monitor the normally susceptible areas for
radiational cooling, especially interior E Mass, the northern CT
valley and even Martha`s Vineyard where they radiate very well
with calm winds. For now, have lows mainly in the 50s, though a
few spots could drop below 50. Could also see patchy low clouds
and fog redevelop after midnight in the normally prone spots.

Saturday...

High pressure continues to slowly shift E, while low pressure
lingers off the mid Atlantic coast. This will keep mainly E winds
in place, and may pick up along the S coast during the afternoon
with gusts possibly up to around 20 mph. Should be another mainly
sunny, warm summer`s day. Highs will range in the lower-mid 80s
away from the coast, mildest across the lower CT valley, but
holding mainly in the 70s along the immediate coast.

Area Forecast Discussion
National Weather Service Taunton MA
651 AM EDT FRI JUN 24 2016

.SYNOPSIS...
Large high pressure will slowly move across the northeast U.S.
into early next week, keeping dry conditions across the region.
Warm to hot temperatures will move in Sunday and Monday, with
showers and thunderstorms possible Tuesday. More seasonable
weather is expected late in the week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

7 am update

Patches of fog in SE Mass and Ct Valley are burning off. Generally
fair skies over the region, and the fair weather will continue
through the day.  No changes planned for the forecast.

Previous discussion

High pressure ridge stretching from the Great Lakes into northern
New England early this morning will slowly shift into the region
this afternoon. With the position of this high, expect N-NE winds
to veer to E-NE during the day but, with a low pressure gradient
in place, winds will generally be at 10 mph or less. Will see some
gusts up to around 15 mph this morning along the immediate S coast
and the islands.

H85 temps start off in the +9C to +12C range this morning, but
should recover to +12C to +14 during the afternoon. With nearly
full summer sunshine, expect temps to recover to the mid 70s to
lower 80s away from the coast, but will remain cooler especially
along the E coast with the onshore winds.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/...
Tonight...

As the ridge axis slowly settles across the region, it will
gradually shift E. Expect mainly clear conditions with light E-SE
winds. Will need to monitor the normally susceptible areas for
radiational cooling, especially interior E Mass, the northern CT
valley and even Martha`s Vineyard where they radiate very well
with calm winds. For now, have lows mainly in the 50s, though a
few spots could drop below 50. Could also see patchy low clouds
and fog redevelop after midnight in the normally prone spots.

Saturday...

High pressure continues to slowly shift E, while low pressure
lingers off the mid Atlantic coast. This will keep mainly E winds
in place, and may pick up along the S coast during the afternoon
with gusts possibly up to around 20 mph. Should be another mainly
sunny, warm summer`s day. Highs will range in the lower-mid 80s
away from the coast, mildest across the lower CT valley, but
holding mainly in the 70s along the immediate coast.

&&

.LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/...
Big Picture...

Longwave pattern continues to show ridge west/trough east through
next week. Shortwave scale shows a ridge over New England Sunday
moving east of us on Monday. A shortwave originating over the
Pacific Northwest moves east across Canada over the weekend and
then digs over New England Tuesday and Wednesday.

Above normal heights with the ridge Sunday-Monday, diminishing to
near normal Tuesday-Wednesday. This suggests above normal temps
Sunday-Monday returning to near normal midweek.

Model forecast mass fields are similar through Monday, then
diverge a little starting Tuesday. Even with the divergence, the
forecast scenarios are similar. This encourages confidence in the
forecast through midweek.

Details...

Saturday night through Monday...

High pressure in control with dry weather. Light flow on Sunday
will support sea breezes along the coasts which will buffer
daytime max temps in those areas while the interior heats up. The
top of the mixed layer Sunday and Monday will be between 800 mb
and 850 mb, with temps supporting max surface temps 85 to 90.
Model temps for Monday actually looked a few degrees too cool.
Suspect sunshine will allow for deeper mixing and warmer temps. We
bumped values up 3 degrees F.

Monday night through Thursday...

Northern shortwave pushes a cold front through the Great Lakes
early week and across New England Tuesday or Wednesday. The GFS
shows the faster timing with passage on Tuesday, while the ECMWF
is slower with cold fropa Wednesday. As the shortwave digs over
the Northeast USA the upper flow turns more southwest and parallel
to the front. This would work to slow down forward progress until
the shortwave axis sweeps through. Thus we favor the slower EC
scenario, but with enough uncertainty to mention chance pops later
Monday night and Tuesday. Stability parameters show potential for
thunder.

Weak high pressure builds dry weather in for Thursday.

.SYNOPSIS...
High pressure strengthens over northern New England from the
northwest and remains into Saturday. This high will move offshore
later in the the weekend and early next week and allow a more
humid air mass to move into the region. A cold front approaching
from the west brings a chance of showers and thunderstorms Monday
night into Tuesday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
6 AM Update...
Some patchy fog developing this morning in valleys and other
favored spots with an ankle deep inversion over the region. This
should mix out quickly this morning and expect fog to dissipate
quickly. Temperatures right now range from the lower 40s in the
western Maine mountains and northern NH to around 60 degrees for
parts of southern NH. Adjusted temperatures for this update.


Previous Discussion...
Quiet conditions continue this morning with clear skies and light
and variable winds. Temperatures have dropped into the 40s and 50s
in a decent radiational cooling environment. With sunny skies and
low dew points temperatures will warm quickly into the 70s and 80s
today. A sea breeze will keep readings along the coast a few
degrees cooler than just inland.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH SATURDAY NIGHT/...
Lows tonight will be in the 40s and 50s. We should see an area of
cooler temperatures in the valleys with another night of ideal
radiational cooling conditions thanks to clear skies and light
winds.

A sunny and warm weekend is on tap for northern New England. High
pressure shifts offshore tonight into tomorrow allowing southerly
flow into the region once again. Dew points begin to slowly
increase during the day Saturday with a few clouds appearing.
Highs will be several degrees warmer for most locations with
increasing heights and south winds becoming established. A sea
breeze is once again expected to keep coastal areas slightly
cooler. Saturday night will be a little warmer than the previous
night with winds a bit higher.

&&

.LONG TERM /SUNDAY THROUGH THURSDAY/...
The large ridge of high pressure across northern New England
Sunday will continue the sunny warm and dry conditions. The next
chance for any showers will be Mon night or Tue in advance of an
approaching trough and cold front from the west. The upper trough
will remain over the area through midweek so unsettled weather
and cooler temperatures expected Tue through Wed. Until
then...warm temperatures expected with increasing humidity levels
for Sunday and Monday.

Previous discussion...

More widespread clearing across SRN New England this evening
partially as shearing vort max shifts S of the region. This will
tend toward clearing skies but noted temps running a bit warmer

clouds in the mountains both days. Flow at the sfc and in the
lower levels aloft will be very weak on Sat which will allow the
sea breeze to develop early and penetrates well inland by the
afternoon. This will produce highs from the low to mid on the
coast /upper 60s at some beaches/ to the low mid 80s inland. The
warmest spots will be the CT valley and Monadnock and Lake Sunapee
regions, in the mid 80s. Sunday will see warmer temps in most

Area Forecast Discussion
National Weather Service Taunton MA
1138 PM EDT THU JUN 23 2016

.SYNOPSIS...
High pressure remains influential over New England through the
weekend. Expect a warming trend which will continue into Monday
with showers and thunderstorms possible Tuesday. More seasonable
weather is expected late in the week.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...

1110 PM Update...

Noting a few bands of cirrus clouds crossing the region on latest
IR satellite imagery at 03Z, otherwise noting mainly clear skies.
03Z observations sowing some low clouds moving into central and
eastern Long Island which will be monitored to see if they work
into portions of the immediate S coast, Cape Cod and the islands
overnight. As high pressure slowly pushes into the region from the
NW, will see light/variable or calm winds.

Temps running mainly in the 60s, though noting a few upper 50s
across the northern CT valley, and up to around 70 in the urban
centers.

Forecast is pretty much on track except for some minor adjustments
on temps/dewpts to bring conditions current.

Previous discussion...

More widespread clearing across SRN New England this evening
partially as shearing vort max shifts S of the region. This will
tend toward clearing skies but noted temps running a bit warmer
than previously forecast. Therefore, only changes were to bring in
more widespread clear skies later tonight and raise mins just a
shade. Still think it will be cool overall, with many places
dropping into the lower 50s before rising again.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/...
Friday...

High pressure in control. Light winds. Beneath cooler air aloft with
H85 temperatures around +10C. But considering the high angle of the
sun, should easily warm back up into the upper-70s to low-80s.
Cooler along the coasts with expected sea-breezes. Dry and
comfortable as dewpoints will range in the 40s to low-50s.

Friday night...

High pressure pushes E. Begin to see return E/SE flow albeit
remaining light. Mostly clear, an opportunity for radiational
cooling and will need to watch those areas with sandy soils in
particular. Leaned cooler of the forecast guidance, mainly towards
MOS. Of greater attention is interior Southeast MA and Marthas
Vineyard which could fall into the 40s. Progged presently in the
low-50s.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Highlights...

 * Warming into Monday
 * Some showers and thunderstorms Tuesday
 * More seasonable WX late week

Overview and model preferences...

Continuance of the nearly zonal flow across the northern CONUS on
the periphery of the cutoff anticyclone across the southern tier
suggests any particular energy/vortex to weaken some upstream. In
fact the building ridge which will bring about this weekend`s heat
is mostly a response to downstream trof development. Given we
remain on the anticyclonic shear side of this zonal flow, the
quiet trend looks to continue for the most part. The only issue is
an opening wave which will traverse this flow and arrive by Tue,
this is currently linked to the PACNW vortex and will gradually
open/weaken as it approaches New England. Otherwise, warmer than
normal temperatures, with generally modest dwpts will define the
next week. Not enough difference in the deterministic guidance
even by mid next week to stray too far from a blend for this
forecast update.

Details...

Sat and Sun...

The primary issue for the weekend will be the heat potential. H85
temps rising to between +12C and +14C should easily be mixed to,
providing at least mid-upper 80s, however, with a modified airmass
and some hint at downslope component to the isallobaric flow,
expect a few places to see the low 90s each day before all is said
and done. Gradient winds remain light but out of the SSW, cooling
RI and SE MA. E coastal sea breezes possible as gradient aloft
likely not strong enough to keep it fully offshore.

Mon...

Chance for a very warm day as return flow develops with high pres
moving E. H85 temps reach near +18C by afternoon. May be some
convective cloud debris from the W to contend with but otherwise,
full mixing expected with temps away from the south coast potentially
rising into the 90s with dwpts increasing to the low 60s. Low risk
for leftover convective shra by evening, but the best theta-e
ridging remains to the W per latest runs. Also to watch, dwpts
will run very close to crossover with S coastal SSTs, so will need
to watch for marine fog/stratus impacts.

Tue and Tue evening...

With wave opening and shifting the low more meridionally approaching
cold front is expected to slow as it reaches New England. Timing
of this feature will once again be key to impacts, as an afternoon
FROPA definitely suggests higher convective risk than an early AM
or late evening passage. At this time, modest cooling aloft suggests
MU CAPE values potentially exceeding 1500j/kg with sfc based values
closer to 1000j/kg. Not a true EML it appears as lapse rates will
only reach about 6.0 or slightly higher. Shear not impressive either
as the mid lvl flow remains relatively weak. Therefore, primary
risk would be heavy rain if any storms form. More to come as we
approach.

Wed and Thu...

Similar setup to this week. Cold front stalls offshore and how close
it sits will ultimately determine whether any MCS or developing
frontal wave could impact Srn New England. High pres to the N
looks to keep it too far S at this time thanks to some phasing of
the initial trof with a secondary Hudson Bay trof late week. This
suggests temps closer to seasonal normals, but a continuation of
the dry wx.

Friday...
NE winds initially with gusts up to 20 kt diminishing while
turning E-SE as high pressure pushes across New England into the
Gulf of Maine. Waves begin to build of 4 feet on the outer waters
but much of this looks to be the result of swell subsequent of
storm activity emerging off the Mid-Atlantic.

Friday Night...
Light winds overall out of the E-NE with high pressure situated
over the Gulf of Maine. Seas of 4 feet continue over the S waters
mainly due to swell from continued storm activity off the Mid-
Atlantic.

Previous discussion...

High pressure settling in as a frontal boundary pushes offshore.
Beneath, cyclonic flow aloft through which mid-level vortex energy
rotates. Perhaps convergence and lift along the front / sea-breeze
coupled with mid-level forcing will yield a spot shower for areas
S of the N CT border towards the S-coast, Cape and Islands? HRRR
seems to suggest and just evaluating the synoptics can not rule
out as we go towards evening. Will prevail with slight chance PoPs.
Closely watching activity out of PA attendant with a mid level
vortex out of the E Great Lakes. Could be just enough of a kicker
up on the low level lift generated by the boundary.

A bigger question is how quickly will dry air move in? Low 60
dewpoints lingering S and E beneath a stabilizing boundary layer
beneath which moisture will pool. Scattered nuisance low clouds
over Nantucket at around 300 feet are likely to expand along and
ahead of the front, most likely as far N as the S-coastline of MA
and RI. Should see improvement and clearing towards morning. Can
not rule out the potential of fog, mainly and mostly a repeat of
soupy conditions on Nantucket.

Otherwise a mild evening as it was warmer earlier in the day. Light

full mixing expected with temps away from the south coast potentially
rising into the 90s with dwpts increasing to the low 60s. Low risk
for leftover convective shra by evening, but the best theta-e
ridging remains to the W per latest runs. Also to watch, dwpts
will run very close to crossover with S coastal SSTs, so will need
to watch for marine fog/stratus impacts.

Tue and Tue evening...

With wave opening and shifting the low more meridionally approaching
cold front is expected to slow as it reaches New England. Timing
of this feature will once again be key to impacts, as an afternoon
FROPA definitely suggests higher convective risk than an early AM
or late evening passage. At this time, modest cooling aloft suggests
MU CAPE values potentially exceeding 1500j/kg with sfc based values
closer to 1000j/kg. Not a true EML it appears as lapse rates will
only reach about 6.0 or slightly higher. Shear not impressive either
as the mid lvl flow remains relatively weak. Therefore, primary
risk would be heavy rain if any storms form. More to come as we
approach.

Wed and Thu...

Similar setup to this week. Cold front stalls offshore and how close
it sits will ultimately determine whether any MCS or developing
frontal wave could impact Srn New England. High pres to the N
looks to keep it too far S at this time thanks to some phasing of
the initial trof with a secondary Hudson Bay trof late week. This
suggests temps closer to seasonal normals, but a continuation of
the dry wx.

Area Forecast Discussion
National Weather Service Taunton MA
725 PM EDT THU JUN 23 2016

.SYNOPSIS...
High pressure remains influential over New England through the
weekend. Expect a warming trend which will continue into Monday
with showers and thunderstorms possible Tuesday. More seasonable
weather is expected late in the week.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...
7 PM Update...
More widespread clearing across SRN New England this evening
partially as shearing vort max shifts S of the region. This will
tend toward clearing skies but noted temps running a bit warmer
than previously forecast. Therefore, only changes were to bring in
more widespread clear skies later tonight and raise mins just a
shade. Still think it will be cool overall, with many places
dropping into the lower 50s before rising again.

Previous discussion...

High pressure settling in as a frontal boundary pushes offshore.
Beneath, cyclonic flow aloft through which mid-level vortex energy
rotates. Perhaps convergence and lift along the front / sea-breeze
coupled with mid-level forcing will yield a spot shower for areas
S of the N CT border towards the S-coast, Cape and Islands? HRRR
seems to suggest and just evaluating the synoptics can not rule
out as we go towards evening. Will prevail with slight chance PoPs.
Closely watching activity out of PA attendant with a mid level
vortex out of the E Great Lakes. Could be just enough of a kicker
up on the low level lift generated by the boundary.

A bigger question is how quickly will dry air move in? Low 60
dewpoints lingering S and E beneath a stabilizing boundary layer
beneath which moisture will pool. Scattered nuisance low clouds
over Nantucket at around 300 feet are likely to expand along and
ahead of the front, most likely as far N as the S-coastline of MA
and RI. Should see improvement and clearing towards morning. Can
not rule out the potential of fog, mainly and mostly a repeat of
soupy conditions on Nantucket.

Otherwise a mild evening as it was warmer earlier in the day. Light
winds across the interior with low dewpoints. Not ruling out
radiational cooling and locations could fall back into the 40s for
lows.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/...
Friday...

High pressure in control. Light winds. Beneath cooler air aloft with
H85 temperatures around +10C. But considering the high angle of the
sun, should easily warm back up into the upper-70s to low-80s.
Cooler along the coasts with expected sea-breezes. Dry and
comfortable as dewpoints will range in the 40s to low-50s.

Friday night...

High pressure pushes E. Begin to see return E/SE flow albeit
remaining light. Mostly clear, an opportunity for radiational
cooling and will need to watch those areas with sandy soils in
particular. Leaned cooler of the forecast guidance, mainly towards
MOS. Of greater attention is interior Southeast MA and Marthas
Vineyard which could fall into the 40s. Progged presently in the
low-50s.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Highlights...

 * Warming into Monday
 * Some showers and thunderstorms Tuesday
 * More seasonable WX late week

Overview and model preferences...

Continuance of the nearly zonal flow across the northern CONUS on
the periphery of the cutoff anticyclone across the southern tier
suggests any particular energy/vortex to weaken some upstream. In
fact the building ridge which will bring about this weekend`s heat
is mostly a response to downstream trof development. Given we
remain on the anticyclonic shear side of this zonal flow, the
quiet trend looks to continue for the most part. The only issue is
an opening wave which will traverse this flow and arrive by Tue,
this is currently linked to the PACNW vortex and will gradually
open/weaken as it approaches New England. Otherwise, warmer than
normal temperatures, with generally modest dwpts will define the
next week. Not enough difference in the deterministic guidance
even by mid next week to stray too far from a blend for this
forecast update.

Details...

Sat and Sun...

The primary issue for the weekend will be the heat potential. H85
temps rising to between +12C and +14C should easily be mixed to,
providing at least mid-upper 80s, however, with a modified airmass
and some hint at downslope component to the isallobaric flow,
expect a few places to see the low 90s each day before all is said
and done. Gradient winds remain light but out of the SSW, cooling
RI and SE MA. E coastal sea breezes possible as gradient aloft
likely not strong enough to keep it fully offshore.

Mon...

Chance for a very warm day as return flow develops with high pres
moving E. H85 temps reach near +18C by afternoon. May be some
convective cloud debris from the W to contend with but otherwise,
full mixing expected with temps away from the south coast potentially
rising into the 90s with dwpts increasing to the low 60s. Low risk
for leftover convective shra by evening, but the best theta-e

316 PM EDT THU JUN 23 2016

.SYNOPSIS...
High pressure will build into northern New England from the
northwest tonight and remain into Saturday. This high will move
offshore later in the the weekend and early next week and provide
a more humid air mass. A cold front approaching from the west
brings a chance of showers and thunderstorms Monday night into
Tuesday.

&&

.NEAR TERM /THROUGH TONIGHT/...
A short wave trough will pass to our east early this evening and
allow for SFC high pressure to build in from the northwest. Skies
will clear out early on and any pop up showers across central and
northern zones will dissipate with the loss of daytime heating.
Winds will go calm or light and variable. Some valley fog is
possible once again tonight as radiational cooling conditions will
be pretty good. Otherwise expect a far and cool night, especially
in outlying areas.

&&

.SHORT TERM /FRIDAY THROUGH FRIDAY NIGHT/...
Nice day in store on Friday as high pressure parks overhead.
Winds will be light along with mostly sunny skies. A seabreeze
will likely make it`s way inland during the afternoon hours. For
highs went a degree or two above a mav/met blend.

A short wave trough will pass through the region Friday night with
very little fanfare except for perhaps a few clouds. Otherwise,
fair and once again cool with the potential for patchy river
valley fog.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...
Chance of high impact wx: Minimal.

The 500 mb pattern in the NE CONUS continues to feature more
troughing than ridging...although will see some periods of both.
The biggest is change is that the cold pool aloft retreats
poleward, bringing less temp change with next trough that will
build in middle of next week.

For the weekend, weak sfc high over the CWA on Sat will strengthento
our east on Sunday as 500 mb ridging builds in and then shifts
offshore. Look for mainly sunny days, with a few clouds in the
mountains both days. Flow at the sfc and in the lower levels aloft
will be very weak on Sat which will allow the sea breeze to
develop early and penetrates well inland by the afternoon. This
will produce highs from the low to mid on the coast /upper 60s at
some beaches/ to the low mid 80s inland. The warmest spots will be
the CT valley and Monadnock and Lake Sunapee regions, in the mid
80s. Sunday will see warmer temps in most places ans we begin to a
more organized SW flow, and highs will will range from the mid-
uppr 70s on the coast to 85-90 inland areas. overnight lows will
be seasonably cool in the 50s.

Monday should be mainly sunny, but will see a few more clouds
around as low level moisture starts to increase and troughing to
the west approaches. Looks to be a another fairly warm day,
although may be a few degrees off Sunday. Models do start
diverging again at this point, especially the 12Z ECMWF, which is
once again slowing the system to the west and associated cold
front, while the GFS and GGEM are more progressive moving it
through Tuesday night. Taking of consensus of models would put the
best chc of showers and thunderstorms Tuesday afternoon and
Tuesday night, but they cannot be ruled out Monday night into
Wednesday at this point. Also, tuesday should turn humid in
advance of the front, but max temps will likely be lower with
cloud cover and potential showers. Wednesday remains very low
confidence at this point, but will maintain some chc pops to cover
the slower moving ECMWF.


&&

.AVIATION /18Z THURSDAY THROUGH TUESDAY/...
Short Term...VFR conditions tonight through Saturday night will
prevail. However patchy vis restrictions late tonight in river
valley fog are possible. Seabreeze likely Friday afternoon.

Sun-Tue. Scattered t-storms possible on Tuesday.

113 PM EDT THU JUN 23 2016

.SYNOPSIS...
An weak upper level disturbance will move across the region today
bringing a chance of showers in the mountains. Otherwise very
little rain is expected into early next week. The heat and
humidity will increase during this time as well.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
110 pm Update...little change to the going forecast. Mainly just
some fair weather cu out there. However a few may grow enough to
produce showers across central and northern zones.

930 am Update...Have updated the going forecast mainly for minor
adjustments to temperatures, sky, and pops for this afternoon.
Short wave trough and attendant cool temperatures aloft will aid
in the development of widely scattered showers across central and
northern zones late this morning and this afternoon. Otherwise,
Partly to mostly sunny skies are expected along with warmer
temperatures than yesterday. Raised max temps today based on
latest observational trends and guidance.

7am update... increased Pops across far northern New Hampshire as
a few showers are moving into Coos county. Elsewhere fog remains
in the river valleys including the CT river valley at Lebanon,
the Androscoggin river valley at Berlin and the Pemi at Plymouth
NH with a few pockets of 1/4 mile visibility.

A quieter day is in store as yesterdays upper vort max has moved
off to the east. Rain during the day on Tuesday has left plenty
of moisture around and fog has formed in sheltered valley
locations. Expect scattered patchy fog to continue for the next
few hours, lingering longest in the CT river valley. Fog will burn
off as the sun rises.

The upper level low remains just to our north centered over Quebec
and will allow for a few showers in the mountains. To our south, a
low pressure will move out of the Ohio river valley and through
the mid atlantic. The rain will stay well to our south but
southern New Hampshire may see increasing clouds through the
afternoon as the system passes.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
High pressure will begin to build back into the region for Friday
with temperatures beginning the steady increase that will
continue through the weekend. Overnight lows will be in the 40s
north to mid 50s south. Fog is possible... especially in the north
but low confidence at this time due to the relatively dry airmass.

Friday a seabreeze will develop. With no pressure gradient to
speak of it will likely move inland quite far /possibly as far as
IZG/. Ocean water temperatures remain around 55 and the sea breeze
will limit high temperature to the 70s in the coastal plain while
southern New Hampshire may see 80.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
High pressure remains in control through the weekend. This will
ensure sunny skies...warm temperatures...and only an outside
chance of a shower. The weekend into Monday we will see a warming
trend with readings reaching the 80s areawide each day. Some
inland and southern sections will approach 90 degrees Sunday and
Monday. Coastal locations will be cooled by a sea breeze each day
and should top out in the 70s.

High pressure shifts offshore Monday allowing southerly flow of
moisture to increase ahead of the next low pressure system.
Increasing pressure gradient may cause some gusty winds Monday and
Tuesday. The surface system hangs up while it waits for the upper
level low...and the system eventually becomes stacked vertically
and begins to weaken before the actual cold front makes it through
NH and ME.

This will make for a few days of increasing cloudiness...showers...
and cooler temperatures as we wait for the boundary to push
through. Depending on timing we could see some decent
thunderstorms Tuesday or Wednesday. Have kept the chance of
showers in through Thursday as the upper level system lingers.

&&

.AVIATION /17Z THURSDAY THROUGH MONDAY/...
Short Term...VFR conditions today through tonight will prevail.
However patchy vis restrictions late tonight in river valley fog
are possible. Seabreeze likely on the immediate coast this
afternoon.

Long Term...Generally VFR conditions expected through the
weekend. Could see some occasional valley fog at night at
Whitefield and possibly Lebanon late at night and into each
morning.

&&

.MARINE...
Short Term...Relatively tranquil waters with winds and seas below
small craft criteria through Friday night.

Long Term...High pressure will be over the Gulf of Maine resulting
in light winds and relatively calm seas through at least Sunday.

&&

.GYX WATCHES/WARNINGS/ADVISORIES...
ME...None.

Area Forecast Discussion
National Weather Service Taunton MA
1032 AM EDT THU JUN 23 2016

.SYNOPSIS...

Low pressure tracking south of New England may bring a few
showers today, mainly along the south coast and islands. Large
high pressure will build across the region Friday and Saturday,
then shift east into early next week. This brings a spell of dry
and warming weather through Monday. An approaching cold front may
bring showers and thunderstorms Tuesday and Wednesday.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...

1030 am update...

Tracking the mesoscale convective complex to our S. Evaluating the
mean wind along with corfidi vector flow in addition to the thermal
and moist axes, majority of this activity is going to stay S. With
additional energy over N New England appearing like a squeeze-play
in an environment not overly condusive for shower / thunderstorm
developing. Yet lowering heights and a weak frontal boundary pushing
offshore, could net some low to mid level forcing with diurnal heating
that may yield a spot shower to which higher confidence is towards
the S and E perhaps enhanced by sea-breeze contributions. There is
some contribution of differential vorticity advection which may
just sqeeze out some forcing with low level lift. Not a lot of
moisture to work with though per 12z soundings.

So an overall quiet day of weather with temperatures warming into
the upper 70s to low 80s with a greater probability of cloud cover
as you go N to S across S New England. Light winds and again sea-
breezes along the shores.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...

Tonight...
As low pressure pushes offshore well S of the region, expect any
lingering showers, and even the low chance for a brief
thunderstorm over the coastal waters this evening, to push
offshore as well. Clouds will exit from NW-SE tonight with drier
air moving in. May see some brief patchy fog develop near
Nantucket again off and on tonight as the drier air will take its
time moving in there.

Expect winds to become light N-NW tonight, stirring just enough to
prevent radiational cooling. Lows will generally be in the 50s,
coolest across the higher inland terrain of N central and NW
Mass., but may hold around 60 along the immediate S coast and on
the islands.

Friday...
Large high pressure will begin to build SE out of south central
Canada and the Great Lakes region on the continued W-NW flow
aloft. Will see abundant sunshine with good subsidence in place.
Expect seasonable temperatures, ranging from the mid 70s along the
immediate coast to the lower-mid 80s, mildest across the lower CT
valley.

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...

Big Picture...

Longwave scale shows a persistent trough in Eastern North America
and ridge over the West. Shortwave scale shows a ridge building over
New England Saturday and Sunday before diminishing late Monday. A
shortwave originating over the Pacific Northwest moves east across
Canada over the weekend and then digs over New England Tuesday and
Wednesday.

The building ridge and increasing contour heights suggest a warming
trend over the weekend. Forecast contour heights are about 120
meters above normal by Sunday. As the shortwave approaches Tuesday-
Wednesday the heights fall and values return to near normal.

Model forecast mass fields are similar through Monday, then diverge
a little early next week. Even with the divergence, the forecast
scenarios are similar. This encourages confidence in the forecast
through early next week.

Details...

Friday night through Monday...High confidence.

Surface high pressure over the region Friday night and Saturday
shifts east by Sunday and Monday. The surface high combined with
building heights aloft will lead to fair weather and a warming trend
through Monday.  A light low level east flow Saturday trends to a
south to southwest flow Sunday and Monday. The mixed layer is
forecast to reach above 850 mb, and may approach 800 mb each day.
This brings 850-equivalent temps of 13-16C Saturday and 16-18C
Sunday and Monday...with surface max temps in the mid and upper 80s
Saturday and upper 80s/lower 90s Sunday and Monday. These temps may
be buffered by flow off the cooler ocean in RI and Eastern Mass,
especially Saturday.

Monday night through Wednesday...Moderate confidence.

Upper shortwave approaches, driving a surface cold front toward New
England. Models show some difference in timing with the ECMWF now
faster than the other models in bringing pcpn into Western New
England later Monday. The rest hold off until Monday night, timing
that we favor. There are also timing differences in the cold front
passage with the ECMWF sooner/GFS later. We will feature chance pops
all areas Tuesday and Wednesday and await resolution of the timing
differences.

.AVIATION /14Z THURSDAY THROUGH MONDAY/...

Forecaster Confidence Levels.

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

Short Term /through Friday/...

Today...high confidence.

VFR. BKN cigs low-end VFR likely along the S-coast. Slight chance
of SHRA S and E along the coast. Sea-breezes already developing
along the coast.

Tonight...High confidence.

VFR. Low chance for MVFR-IFR VSBYS in patchy fog INVOF KACK and
the outer Cape around or after 03Z, that should improve by daybreak.

Friday...High confidence. VFR.

KBOS TAF...Sea breeze should be in by 15z. VFR overall with SCT to
BKN cigs.

KBDL TAF...VFR. Winds are light presently but should see an
increase through the day out of the S and W.

Outlook /Friday Night through Monday/... High confidence.

Areas of IFR and LIFR in late night/early morning fog. Otherwise
VFR. Sea Breezes expected Saturday.

&&

.MARINE...

Forecaster Confidence Levels.

Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.

Short Term /through Friday/...High confidence.

1030 am update...no major changes to the forecast at this time.

Today...Seas are slowly subsiding with leftover 5-foot swell just
outside the outer waters. With conditions trending lighter, we
will end the small craft advisory that was in effect overnight.
Showers will pass south of the waters. An isolated shower might
bring brief lower vsbys to the southern outer waters this
afternoon.

Tonight and Friday...Winds and seas will remain below small craft
criteria. May see some leftover visibility restrictions in patchy
fog and any lingering showers tonight across the southern waters
mainly from E of Cape Cod to S of Nantucket and Martha`s Vineyard.
Should improve toward daybreak Friday.

Outlook /Friday Night through Monday/...Moderate confidence.

Winds remain below 25 knots and seas below 5 feet through the
period. The southern waters may experience a 4 foot swell Saturday
and a 3 to 4 foot swell Sunday. Coastal sea breezes possible
Saturday all coasts and Sunday-Monday south coast.
