HAWAIIAN ISLANDS SATELLITE INTERPRETATION MESSAGE
NWS CENTRAL PACIFIC HURRICANE CENTER HONOLULU HI
0030 UTC TUE MAY 24 2016

BASED ON DATA THROUGH 0000 UTC MAY 24 2016

WEAKENING SURFACE HIGH PRESSURE NORTHEAST OF THE STATE CONTINUED
SEND SCATTERED TO BROKEN LOW CLOUD PATCHES INTO THE STATE FROM THE
EAST. THE AMOUNT OF CLOUDS HAD LESSENED AROUND THE ISLANDS SINCE THE
EARLY TO MID MORNING HOURS DUE TO EVAPORATION FROM THE HEAT OF THE
SUN. THE CLOUDS NEAR THE ISLANDS WERE MOVING WEST WITHIN THE TRADE
WIND FLOW AROUND 15 MILES AN HOUR THIS AFTERNOON. CLOUD TOPS WERE
MOSTLY BETWEEN 8000 AND 11000 FEET. FURTHER TO THE NORTHEAST...THE
LOW CLOUDS WERE A BIT MORE NUMEROUS NORTH OF 20N AND EAST OF 150W.

AT 2 PM HST...SKIES WERE SUNNY TO PARTLY CLOUDY OVER MOST AREAS OF
STATE. BUT THE WEST HALF OF THE BIG ISLAND HAD BECOME CLOUDY TO
MOSTLY CLOUDY. AND IT WAS SUNNY TO MOSTLY SUNNY OVER THE WATERS
IMMEDIATELY SURROUNDING THE ISLANDS.

A TROUGH OF LOW PRESSURE EXTENDED DOWN THROUGH 30N 172W TO 25N 178W.
THE TROUGH WAS NEARLY STATIONARY. BROKEN TO OVERCAST LAYERED CLOUDS
STRADDLED THE TROUGH. THE ASSOCIATED CLOUD BAND...ROUGHLY 175 MILES
WIDE...WAS CENTERED ALONG A LINE FROM 31N 170W TO 27N 180E. THE
CLOUD BAND ALSO CONTAINED ISOLATED THUNDERSTORMS NORTH OF 27N TO THE
EAST OF 172W.

Area Forecast Discussion
National Weather Service Honolulu HI
956 AM HST MON MAY 23 2016

.SYNOPSIS...
Trade winds will gradually decrease over the next few days, with
afternoon sea breezes becoming widespread over leeward areas by
Wednesday. Moderate showers will continue to favor windward
slopes into Tuesday, and chances for heavier showers will
increase over mainly windward areas on Tuesday night and over
leeward areas Wednesday afternoon as the atmosphere becomes
unstable. A more stable, hybrid trade wind and weak afternoon
convective pattern will prevail on Thursday and Friday, followed
by light and variable winds and a land and sea breeze pattern over
most islands this weekend.

&&

.DISCUSSION...
Trade winds are on a weakening trend, while stable conditions
continue to focus clouds and showers over windward slopes.
Surface high pressure centered roughly 1100 miles northeast of the
state is being eroded and pushed eastward by an approaching front.
As a result, winds locally are down off their weekend peak and
will continue a slow decline during the next couple of days. Low
level ridging is keeping the atmosphere somewhat stable, even
though weak upper level troughing overhead is inhibiting a well-
established inversion from forming. Expect moderate showers to
continue to be focused over windward slopes, with pockets of
moisture riding through. The next such pocket is about 75 miles
northeast of Maui and is expected to impact the state later today
and tonight.

On late Tuesday night and Wednesday, unstable conditions will
develop as a somewhat strong mid to upper level trough swings over
and north of the islands. As this feature approaches Tuesday
night, trade winds will become easterly and may shift out of the
east-southeast, possibly setting up conditions for some heavy
showers along windward slopes of the Koolau Range on Oahu. As
trades weaken further on Wednesday and instability is maximized,
afternoon sea breezes will likely trigger spotty convection over
leeward and interior areas of the islands. According to the GFS
and ECMWF, the deepest moisture will be held off to the northeast,
but we will take a close look at including a chance for heavy
showers in the official forecast.

A hybrid trade wind / convective pattern will continue on Thursday
and Friday, though conditions are expected to be more stable as
the upper level trough departs. The weak trade winds will produce
modest showers over windward slopes. Meanwhile, afternoon sea
breezes will generate clouds and a few afternoon showers over
leeward and interior sections, followed by clearing at night as
land breezes develop.

Heading into the weekend, trade winds are expected to be cutoff
over most islands. While southeast winds may hang on over the Big
Islands, most islands should experience a humid land and sea
breeze regime, featuring afternoon clouds and spotty interior
showers with partial clearing at night. Details remain unclear at
this time, but volcanic emissions may be drawn up over the smaller
islands.

Uncertainty increases for early next week. Odds are high that
trade winds will remain suppressed and that a land and sea breeze
regime will continue. The GFS and ECMWF are hinting at another
upper level trough dropping toward the state which could enhance
convection again on the Memorial Day holiday.

&&

.AVIATION...
Trade wind flow will focus patchy clouds and isolated showers
along the windward slopes and coasts of all islands. Isolated MVFR
ceilings and visibilities are expected in passing showers,
especially over the southeastern half of the state.

Weak sea breezes and abundant moisture will combine along the
Kona coast of the big island to encourage afternoon and evening
convective build-ups over inland areas. Partial clearing is
expected across leeward big island after midnight.

VFR conditions are expected to prevail through at least early
Tuesday. No AIRMETS in effect or anticipated at this time.

&&

.MARINE...
Trade winds will be gradually declining during the next couple of
days. A Small Craft Advisory (SCA) remains in place for the
typically windy waters around the Big Island and Maui today.
Expect the SCA to be down by tonight, and there is high confidence
that once down, the SCA flag will remain down into early next
week.

Small surf will dominate over most shores this week. The one
exception is a small southwest swell that should build on
Thursday, peak on Friday, then decline during the weekend. This
swell will originate from the Tasman Sea, and given the large
amount of island blocking on swells from this direction, surf
locally tends to be inconsistent.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
Small Craft Advisory until 6 PM HST this evening for Maalaea Bay-
Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big
Island Southeast Waters.

Area Forecast Discussion
National Weather Service Honolulu HI
830 PM HST SUN MAY 22 2016

.SYNOPSIS...
Trade wind weather will continue through the first half of the week
as high pressure remains far northeast. Winds will ease Wednesday as
a trough moves to north of the area. Showers will favor windward and
mauka areas through Tuesday before a convective pattern brings
afternoon showers and humid conditions for the second half of the
week.

&&

.DISCUSSION...
A surface high pressure far to the northeast continues to bring
moderate to locally strong trade winds across the state this
evening. Locally breezy trade winds will persist through Monday
then easing slowly on Tuesday as the surface high moves further
east. Until then, trade wind weather is expected to prevail across
the state through Tuesday, with passing low clouds and showers
affecting mainly windward areas. Winds may still be strong enough to
carry some showers to lee areas of the smaller islands on Sunday.
Big Island lower leeward area will see clearing skies overnight and
early mornings will give way to cloudy skies with some showers in
the afternoons and evenings.

By Wednesday, a surface trough moving to north of the state will
result in synoptic winds turning more southeast and becoming light
over the islands. This allows more widespread leeward sea breezes to
develop during the day with light to moderate east-southeast winds
remain along the windward coasts. Showers will continue to focus
over the windward slopes and mountains but an increase in afternoon
showers is expected for the lee areas as the daytime sea breezes
develops.

Latest forecast models still show an upper trough bringing colder
air aloft Tuesday night through Wednesday. This will lead to an
increase in shower activity as the air mass over the islands becomes
more unstable.

Forecast models also indicate the surface trough may persist north
of the state through the later half of the week into early next
week...keeping leeward variable winds with windward light to
moderate east-southeast winds across the area. Therefore, the
convective weather scenario may prevail. It will also feel more hot
and humid under the light wind conditions.

&&

.AVIATION...
Brief MVFR conditions are expected over the windward slopes
overnight due to clouds and showers moving in with the trades.
VFR conditions otherwise will prevail across main hawaiian
islands. Lo level turb due to the breezy trade winds will keep
AIRMET TANGO going through the overnight hours and likely into
Monday.

&&

.MARINE...
The small craft advisory remains across the typically windy
waters around the Big Island and Maui. Winds are expected to relax
slightly through Monday, then weaken further Tuesday into Wednesday.
The small craft advisory will likely be dropped by Monday night as
conditions improve.

Surf will remain below advisory levels on all shores through the
forecast period. Small background surf will be affecting all shores.
A small southwest swell is possible this week.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
Small Craft Advisory until 6 PM HST Monday for Maalaea Bay-
Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big

400 AM HST SUN MAY 22 2016

.SYNOPSIS...
Trade wind weather will continue this week as high pressure remains
to our northeast. Clouds and showers will favor windward and mauka
areas. Expect winds to stay locally breezy through Monday, then
easing quite a bit on Tuesday and Wednesday as a weak surface trough
is expected to develop in the island vicinity. Furthermore, an
uptick in rainfall is possible Tuesday night and Wednesday as the
air mass in the island vicinity may become more unstable. More
robust trade winds are expected to return for the later part of the
week.

&&

.DISCUSSION...
A surface high pressure far northeast of the islands continues to
provide moderate to locally breezy trade winds across the area
today. There was an increase in clouds and showers in the island
vicinity overnight as a band of low clouds from the east reaching
the area. Much of the low clouds and showers carried by the winds
will affect mainly windward areas. Morning soundings from Lihue and
Hilo indicated not much changes to the air mass in the island
vicinity since Saturday afternoon, though the trade wind inversion
looked a little weaker. In fact, latest radar data indicated some of
those passing clouds have a rather high cloud tops to over ten
thousand feet. Regardless, do expect more clouds and showers mainly
for the windward areas today.

Latest forecast models still indicate trade wind weather will mostly
prevail across the islands this week. Winds are expected to weaken
quite a bit by Tuesday and Wednesday as a weak surface trough is
expected to develop in the island vicinity. This is in response to
an upper level trough passing over the islands by around Wednesday.
In fact, winds may become weak enough on Tuesday night and Wednesday
such that land and sea breezes may become more widespread across the
islands. The state may also see an increase in shower activity at
the same time, as the upper level feature brings colder temperatures
aloft, thus providing some instability to the air mass in the island
vicinity. As the upper level trough exits east of the islands on
Thursday, more stable atmospheric conditions are expected to return
to the area, with trade winds increase slightly as well.

&&

.AVIATION...
A line of clds and showers continues to close in on the islands
from the ne. It is currently 150 miles ene of the islands. If it
holds together...it will bring widespread mtn obscuration and
AIRMET SIERRA to many of the islands starting around 17/18z. MVFR
conds may last into the early afternoon hours. These clouds and
showers will frequently drift downwind into the leeward areas of
the smaller islands as well. The lee side of the big island will
have some isol to scattered showers this afternoon lasting into
the evening.

AIRMET TANGO for lo lvl turb will likely continue through today.

&&

.MARINE...
Winds are still strong enough to continue the small craft advisory
across the typically windy waters around the Big Island and Maui, as
well as the Kaiwi channel through this evening. Winds are expected
to ease slightly tonight and Monday...with conditions improving over
Kaiwi channel. The small craft advisory will probably be dropped by
Monday night as winds decrease further.

Surf will remain below advisory levels on all shores through the
forecast period. Small background surf will affect all shores. A
small southwest swell is possible by Wednesday.

&&

.HFO WATCHES/WARNINGS/ADVISORIES...
Small Craft Advisory until 6 PM HST Monday for Maalaea Bay-
Pailolo Channel-Alenuihaha Channel-Big Island Leeward Waters-Big

.SYNOPSIS...
Trade wind weather will continue through next week as high pressure
remains to our northeast. Clouds and showers will favor windward and
mauka areas. Expect winds to stay locally breezy through early part
of next week before dropping to moderate levels. An uptick in
rainfall is possible Tuesday night and Wednesday.

&&

.DISCUSSION...
As a surface high pressure far northeast continues to provide
moderate to locally strong trade winds across Hawaii, locally
breezy trade winds will remain through rest of the evening into
early Sunday morning. Latest satellite imagery as well as radar data
showed rather sparse areal coverage of clouds and showers. Much of
the low clouds and showers carried by the winds will affect mainly
windward areas. Mainly fair weather will prevail over most of the
lee areas through rest of the evening into early Sunday morning. The
exception will be Kona area of the big island...where lingering low
clouds will persist, possibly bringing some showers.

Latest forecast models still indicate trade wind weather will
persist across the islands through next week. Winds are expected to
weaken a bit by the middle of next week as a surface trough is
expected to deepen slight in the island vicinity. This is a response
to an upper level trough passing over the islands by around
Wednesday. This may also lead to an increase in shower activity
across the area late Tuesday into Wednesday, as the upper level
feature brings colder temperatures aloft, thus providing some
instability to the air mass in the island vicinity. More stable
atmospheric conditions are expected to return toward the later part
of next week, with trade winds increase slightly.

&&

.AVIATION...
Expect a VFR night as high pressure continues across the area. clds
and showers riding in with the trade winds will bring brief mvfr
conditions to windward and mtn areas of all islands. We will be
monitoring closely for any widespread mtn obsc leading to an AIRMET
SIERRA.
