847 PM CDT THU OCT 30 2014

EXIST WITH AROUND 0.5 INCH PWS AREAWIDE. DUE TO SOME ISENTROPIC
LIFT IN THE N...SOME MID/HIGH CLOUDS ARE MOVING THROUGH BUT NOT
EXPECTING THESE TO IMPACT LOWS TONIGHT. WV IMAGERY INDICATES A S/WV
MOVING THROUGH E AR. AS THIS AND ANOTHER STRONG S/WV OVER NRN MN
MOVES SE AND GRADUALLY PHASES WITH THE DEEP UPPER TROUGH OVER THE
ERN CONUS TONIGHT INTO FRIDAY...EXPECT THE FRONT TO THE W TO MOVE
THROUGH AND STRONG HIGH PRESSURE OVER THE NRN HIGH PLAINS TO
GRADUALLY TO BUILD TO THE SE. DUE TO A STRONG INCREASING PRESSURE
GRADIENT FROM HIGH PRESSURE BUILDING IN...WINDS WILL GRADUALLY
INCREASE IN THE DELTA EARLY TOMORROW MORNING. OVERALL...LOWS LOOK
GOOD OVERNIGHT. MADE SMALL TWEAKS TO HOURLY TEMPS/DEWPOINTS/SKY
GRIDS. REST OF THE FORECAST IS ON TRACK. /DC/

&&

.AVIATION... ALTHOUGH THERE WILL BE SOME SCT-BKN ALTOCUMULUS OVER
GLH-GWO-GTR BEFORE 06Z...VFR CONDITIONS WILL PREVAIL. SOME
STRATOCUMULUS WILL ALSO DEVELOP BY 31/17Z AND MAY BECOME BROKEN
AROUND GTR/MEI...BUT CEILINGS SHOULD REMAIN AT OR ABOVE 3500 FT.
WINDS WILL BE GENERALLY CALM OVERNIGHT...BUT INCREASE FROM THE
NORTHWEST BY 31/17Z WITH SUSTAINED 15 AND GUSTS TO 25 KNOTS COMMON
IN THE AFTERNOON. /26/

&&

.PREV DISCUSSION... /ISSUED 421 PM CDT THU OCT 30 2014/

SHORT TERM...TONIGHT THROUGH SATURDAY NIGHT...ANOTHER COOLER AND
DRIER AIRMASS IS IN PLACE OVER THE REGION FOLLOWING YESTERDAYS COLD
FRONT PASSAGE. THE 12Z KJAN SOUNDING SHOWED 0.36 INCH PW VALUES OVER
THE AREA. ANOTHER COLD FRONT IS EXPECTED TO MOVE INTO THE AREA ON
FRIDAY. THIS WILL ONLY REINFORCE THE COOLER AIRMASS IN PLACE.
OVERNIGHT LOWS ON SATURDAY MORNING WILL BRING THE POTENTIAL FOR OUR
FIRST FREEZE FOR SOME LOCATIONS. HOWEVER...A TIGHTENED PRESSURE
GRADIENT MAY LIMIT JUST HOW COLD WE GET. WHILE FROST WILL BE POSSIBLE
IN SOME PLACES...THIS SUSTAINED WIND WILL ALSO LIMIT HOW WIDESPREAD
FROST WILL BE. IT LIKELY WOULD BE CONFINED TO NORTHERN PORTIONS OF
THE AREA.

HIGHS ON SATURDAY WILL BE BELOW NORMAL FOR THE AREA WITH TEMPERATURES
RUNNING IN THE 50S AND LOWER 60S THANKS TO DECENT CAA. ANOTHER NIGHT
OF MORE WIDESPREAD FREEZING TEMPERATURES WILL BE POSSIBLE SUNDAY
MORNING AS THE 1030MB SFC HIGH SETTLES OVER THE REGION. THIS
WILL ALLOW FOR MUCH CALMER WINDS OVERNIGHT AND CLEAR SKIES. THIS
LIKELY WILL BE THE COLDEST NIGHT WE HAVE SEEN THUS FAR THIS SEASON.
WIDESPREAD FROST MAY BE MORE OF A CONCERN SATURDAY NIGHT/SUNDAY
MORNING AND WILL KEEP MENTION OF THIS IN THE HWO AND GRAPHICS. /28/

LONG TERM...SUNDAY THROUGH THURSDAY...EXPECT WARMER TEMPERATURES ON
SUNDAY WITH SOUTHEAST WINDS AND SUNNY SKIES WITH HIGHS IN THE 60S.
THE WARMUP WILL CONTINUE ON MONDAY WITH STRONG SURFACE RIDGING AND
WARM SOUTHEAST FLOW. THINGS WILL CHANGE ON TUESDAY WITH A DEEP UPPER
TROUGH OVER THE PLANES AND ASSOCIATED COLD FRONT THAT WILL EXTEND
ACROSS ARKANSAS INTO NORTHEAST TEXAS BY TUESDAY MORNING. EXPECT MOST
OF THE AREA TO REMAIN DRY ON TUESDAY AS THE SURFACE RIDGE HANGS ON
OVER THE AREA. BOTH THE GFS/ECMWF BRING THE BOUNDARY INTO THE DELTA
TUESDAY NIGHT INTO WEDNESDAY WITH SHOWERS AND THUNDERSTORMS
DEVELOPING. THE MODELS DIVERGE IN THERE SOLUTIONS WEDNESDAY AND
THURSDAY WITH GFS MORE PROGRESSIVE WITH THE BOUNDARY DRYING THINGS
OUT THURSDAY...BUT ECMWF CUTS OFF A LOW OVER WEST TEXAS AND KEEPS THE
BOUNDARY OVER THE AREA THROUGH THURSDAY WITH A CONTINUED CHANCE FOR
THUNDERSTORMS. WILL KEEP THUNDERSTORM CHANCES IN THE FORECAST THROUGH
THE END OF THE PERIOD. /15/

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
1044 AM CDT THU OCT 30 2014

.UPDATE...A PLEASANT FALL DAY IS IN STORE FOR THE REGION FOLLOWING
YESTERDAYS COLD FRONT PASSAGE. 12Z KJAN SOUNDING SHOWED A DRY AIRMASS
IN PLACE WITH PW VALUES AROUND 0.36 INCHES. SURFACE ANALYSIS SHOWS 1022MB
HIGH PRESSURE IN PLACE OVER THE REGION WHICH WILL KEEP SUNNY SKIES
AND COOL TEMPERATURES IN PLACE. HIGHS WILL REACH INTO THE 70S FOR
MANY LOCATIONS TODAY THROUGH UPPER 60S MAY BE POSSIBLE IN THE GOLDEN
TRIANGLE WHERE MORNING TEMPERATURES HAVE BEEN ON THE COOLER SIDE.
GOING FORECAST IS IN GOOD SHAPE AND ONLY MINOR CHANGES FOR CURRENT
TRENDS WERE NEEDED. /28/

&&

.AVIATION...VFR CONDITIONS WILL PREVAIL AT ALL TAF SITES OVER THE

.PREV DISCUSSION... /ISSUED 350 AM CDT THU OCT 30 2014/

SHORT TERM...TODAY THROUGH FRIDAY NIGHT...IN THE WAKE OF
WEDNESDAY`S COLD FRONT A COOLER AND DRIER AIRMASS HAS SETTLED OVER
OUR CWA. THE 00Z THU JAN SOUNDING HAD A PW OF THREE QUARTERS OF AN
INCH. THE BLENDED TOTAL PW PRODUCT SHOWS PWS LESS THAN A HALF INCH
DROPPING SOUTH ACROSS OUR DELTA REGION. LATEST SURFACE ANALYSIS HAD
A 1022MB RIDGE AXIS FROM THE ARKLATEX TO THE MID MISSISSIPPI VALLEY.
WATER VAPOR IMAGERY/RUC ANALYSIS HAD A BROAD TROUGH OVER THE EASTERN
CONUS. THE RESULTING DEEP NORTHWEST TO NORTHERLY FLOW WILL MAINTAIN
DRY CONDITIONS OVER OUR CWA TODAY. UNDER NEAR FULL INSOLATION AND
WEAK CAA AFTERNOON HIGHS WILL TOP OUT A FEW DEGREES COOLER THAN
NORMAL AT MOST LOCATIONS FROM THE UPPER 60S TO LOWER 70S. STRONG
RADIATIONAL COOLING OF OUR DRY AIRMASS TONIGHT WILL LEAD TO ANOTHER
NIGHT OF COOLER THAN NORMAL TEMPERATURES. MODELS REMAIN IN GOOD
AGREEMENT THAT TONIGHT A POTENT SHORTWAVE WILL DROP OUT OF CANADA
AND CLOSE OFF FRIDAY MORNING OVER THE SOUTHERN GREAT LAKES THEN
DROP SOUTHEAST OVER THE CAROLINAS BY SATURDAY MORNING. THIS WILL
SEND A REINFORCING SHOT OF COOLER AND DRIER AIR SOUTH TOWARD OUR
CWA. THE ASSOCIATED >1030MB CENTER OF HIGH PRESSURE WILL DROP FROM
THE NORTHERN PLAINS TO THE MID MISSISSIPPI RIVER VALLEY BY SATURDAY
MORNING. THE RESULTING PRESSURE GRADIENT WILL LEAD TO GUSTY NORTH
WINDS BY FRIDAY AFTERNOON HOLDING AFTERNOON HIGHS IN THE 60S ACROSS
OUR NORTHERN HALF OF OUR AREA WHILE THE SOUTHERN HALF TOPS OUT NEAR
NORMAL IN THE LOWER 70S. THE PRESSURE GRADIENT WILL RELAX FRIDAY
EVENING ALLOWING THE WIND TO DECOUPLE. NEAR IDEAL RADIATIVE COOLING
THIS COOLER AND DRIER AIRMASS WILL SEND TEMPERATURES INTO THE 30S BY
SATURDAY MORNING. THESE WILL BE THE COOLEST TEMPERATURES OF THE
SEASON WITH THE FIRST OCCURRENCE OF LIGHT FROST AND FREEZING
TEMPERATURES POSSIBLE OVER MUCH OF OUR AREA. THE GFSMOS MORNING LOWS
FOR SATURDAY WERE AGAIN AMONG THE LOWEST ENSEMBLE MEMBERS. THE BULK
OF THE COLDEST AIR WILL BE EAST OF OUR CWA. OUR NORTHEAST ZONES MAY
SEE FREEZING TEMPERATURES FOR AN HOUR OR TWO WITH MID 30S POSSIBLE
SOUTH AND WEST. PATCHY FROST WILL BE POSSIBLE AREAWIDE. SENSITIVE
VEGETATION WILL NEED TO BE PROTECTED FRIDAY NIGHT AND WE WILL CARRY
THIS MENTION IN THE HWO. /22/

LONG TERM...SATURDAY THROUGH THURSDAY...HIGH PRESSURE WILL BE
CENTERED OVER THE NORTHERN PORTIONS OF THE STATE BY SATURDAY
AFTERNOON. A COOL DAY WILL BE ON TAP WITH HIGHS ONLY IN THE
MID/UPPER 50S FOR MOST OF THE AREA. THE SURFACE HIGH WILL SHIFT TO
THE NORTHEAST OF THE AREA ON SATURDAY NIGHT INTO SUNDAY AND THIS
WILL ALLOW THE SURFACE FLOW TO SHIFT TO THE EAST THEN SOUTHEAST BY
SUNDAY. EXPECT ONE MORE COLD NIGHT SATURDAY NIGHT INTO SUNDAY AS
LIGHT SURFACE FLOW WILL ALLOW STRONG RADIATIONAL COOLING AND LOW
TEMPERATURES AROUND 30 DEGREES OR POSSIBLY THE UPPER 20S. THIS COULD
BE THE COLDEST NIGHT WE HAVE SEEN THIS FALL THUS FAR.

EXPECT WARMER TEMPERATURES ON SUNDAY WITH SOUTHEAST WINDS AND SUNNY
SKIES WITH HIGHS IN THE 60S. THE WARMUP WILL CONTINUE ON MONDAY WITH
STRONG SURFACE RIDGING AND WARM SOUTHEAST FLOW. THINGS WILL CHANGE
ON TUESDAY WITH A DEEP UPPER TROUGH OVER THE PLANES AND ASSOCIATED
COLD FRONT THAT WILL EXTEND ACROSS ARKANSAS INTO NORTHEAST TEXAS BY
TUESDAY MORNING. EXPECT MOST OF THE AREA TO REMAIN DRY ON TUESDAY AS

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
857 PM CDT WED OCT 29 2014

.UPDATE...
QUIET NIGHT IN STORE IN THE WAKE OF THE COLD FRONTAL PASSAGE. DRIER
AIR CONTINUES TO FILTER INTO THE REGION WITH DEWPOINTS FALLING INTO
THE MID/UPPER 40S WHILE DEWPOINTS IN S MS NEAR THE FRONT ARE IN THE
MID 50S/LOW 60S. 00Z REGIONAL SOUNDINGS INDICATE DRIER AIR FILTERING
IN AS PWATS AT KJAN HAVE FALLEN TO AROUND ~0.7 INCHES WITH LESS THAN
HALF AN INCH AT KLZK. 1022MB SURFACE HIGH WILL BUILD IN OVERNIGHT AND
LEAD TO A COLD NIGHT WITH GOOD RADIATIONAL COOLING DUE TO CLEAR NIGHT
AND CALM WINDS. LOWS WILL BE MAINLY IN THE LOW/MID 40S. OTHER THAN
SMALL CHANGES TO HOURLY TEMP/DEWPOINT/SKY GRIDS...REST OF THE
FORECAST IS ON TRACK. /DC/

&&

.AVIATION...VFR CONDITIONS WITH LIGHT WINDS WILL PREVAIL THROUGH THE
PERIOD. /26/

&&

.PREV DISCUSSION... /ISSUED 355 PM CDT WED OCT 29 2014/

DISCUSSION...

TONIGHT THROUGH THURSDAY...

EXPECT DRY AND COOLER CONDITIONS TONIGHT AS HIGH PRESSURE BUILDS IN
BEHIND A COLD FRONT WHICH PASSED THROUGH THE CWA. LOWS TONIGHT WILL
RANGE FROM THE LOWER 40S NORTH TO THE MID 40S SOUTH. LOTS OF
SUNSHINE IN STORE FOR THURSDAY AS HIGH PRESSURE WILL BE IN CONTROL.
HIGHS WILL MAINLY BE IN THE LOWER 70S. DRY AND COOL AGAIN THURSDAY
NIGHT WITH LOWS IN THE 40S. /27/

FRIDAY THROUGH WEDNESDAY...

COOLER THAN NORMAL AND DRY THROUGH MONDAY MORNING THEN WARMER THAN
NORMAL WITH RAIN CHANCES INCREASING TUESDAY INTO WEDNESDAY. COME
FRIDAY MORNING A RATHER AMPLIFIED PATTERN OF RIDGING ALOFT OVER THE
ROCKIES AND UPPER LEVEL TROUGHING OVER THE EASTERN CONUS WILL BE IN
PLACE. MODELS INDICATE A POTENT SHORTWAVE CLOSING OFF FRIDAY MORNING
OVER THE SOUTHERN GREAT LAKES AND DROPPING SOUTHEAST OVER THE
CAROLINAS BY SATURDAY MORNING. THIS WILL SEND A REINFORCING SHOT OF
COOLER AND DRIER AIR SOUTH TOWARD OUR CWA. THE ASSOCIATED HIGH
PRESSURE CENTER WILL DROP FROM THE NORTHERN PLAINS TO THE MID
MISSISSIPPI RIVER VALLEY BY SATURDAY MORNING. THE RESULTING PRESSURE
GRADIENT WILL LEAD TO GUSTY NORTH WINDS BY FRIDAY AFTERNOON HOLDING
AFTERNOON HIGHS IN THE 60S ACROSS OUR NORTHERN ZONES WHILE THE
SOUTHERN ZONES TOP OUT NEAR NORMAL IN THE LOWER 70S. THE PRESSURE
GRADIENT WILL RELAX FRIDAY EVENING BUT THE WIND MAY NOT TOTALLY
DECOUPLE BY MORNING AND MAINTAIN SOME MIXING. OTHERWISE...NEAR IDEAL
RADIATIVE COOLING OF OUR COOL DRY AIRMASS WILL SEND TEMPERATURES
INTO THE 30S BY MORNING. THESE WILL BE THE COOLEST TEMPERATURES OF
THE SEASON WITH PATCHY LIGHT FROST POSSIBLE OVER MUCH OF OUR AREA.
SATURDAY THE SURFACE RIDGE WILL MOVE OVER OUR CWA AS THE HIGH SHIFTS
EAST. THIS WILL RESULT IN A MUCH LIGHTER WIND THAN ON FRIDAY BUT
TEMPERATURES WILL ONLY TOP OUT IN THE 50S AT MOST SITES. THE SURFACE
HIGH WILL CONTINUE SHIFTING EAST THROUGH SUNDAY AS WELL AS RIDGING
ALOFT. THE COLDEST MORNING OF THE PERIOD IS EXPECTED SUNDAY MORNING
AS ANOTHER NIGHT OF STRONG RADIATIVE COOLING IS EXPECTED. MORNING
LOWS WILL BE BACK IN THE 30S AREAWIDE AND OUR NORMALLY COLDER
LOCATIONS MIGHT SEE FREEZING TEMPERATURES FOR THE FIRST TIME THIS
SEASON. LIGHT RETURN FLOW IS EXPECTED BY SUNDAY AFTERNOON AS THE
SURFACE HIGH BECOMES CENTERED OVER THE MID ATLANTIC SEABOARD. THE
RIDGE ALOFT WILL BECOME CENTERED OVER OUR CWA SUNDAY AFTERNOON AS
WELL. THIS WILL ALLOW TEMPERATURES TO CLIMB INTO THE 60S SUNDAY
AFTERNOON BUT NORMAL HIGHS RUN IN THE LOWER 70S. NORMAL LOWS RUN IN
THE UPPER 40S TO NEAR 50 DEGREES. BELOW NORMAL TEMPERATURES ARE
EXPECTED SUNDAY NIGHT WITH SITES BOTTOMING OUT IN THE LOW TO MID
40S. THE WARMING TREND WILL CONTINUE INTO WEDNESDAY AND MOISTURE
WILL GRADUALLY RETURN TO OUR CWA. MODELS ARE IN BETTER AGREEMENT
THIS MORNING WITH ANOTHER CLOSED LOW AND COLD FRONT THAT SHOULD
BEGIN INCREASING RAIN CHANCES OVER OUR CWA TUESDAY AND WEDNESDAY. A
CLOSED LOW IS EXPECTED TO BE OVER BAJA TUESDAY AFTERNOON WITH A
WEAKENING COLD FRONT JUST NORTHWEST OF OUR CWA TUESDAY AFTERNOON.
MODEL CONSENSUS DROPS THE WEAK COLD FRONT INTO OUR NORTHWEST AS THE
CLOSED LOW TRACKS EAST TOWARD WEST TEXAS THROUGH WEDNESDAY. THE
MOISTURE DRAWN NORTH FROM THE CLOSED LOW WITH THE PRESENCE OF THE
FRONTAL BOUNDARY SHOULD LEAD TO CHANCE POPS ACROSS OUR REGION

.DISCUSSION...

TONIGHT THROUGH THURSDAY...

EXPECT DRY AND COOLER CONDITIONS TONIGHT AS HIGH PRESSURE BUILDS IN
BEHIND A COLD FRONT WHICH PASSED THROUGH THE CWA. LOWS TONIGHT WILL
RANGE FROM THE LOWER 40S NORTH TO THE MID 40S SOUTH. LOTS OF
SUNSHINE IN STORE FOR THURSDAY AS HIGH PRESSURE WILL BE IN CONTROL.
HIGHS WILL MAINLY BE IN THE LOWER 70S. DRY AND COOL AGAIN THURSDAY
NIGHT WITH LOWS IN THE 40S. /27/

FRIDAY THROUGH WEDNESDAY...

COOLER THAN NORMAL AND DRY THROUGH MONDAY MORNING THEN WARMER THAN
NORMAL WITH RAIN CHANCES INCREASING TUESDAY INTO WEDNESDAY. COME
FRIDAY MORNING A RATHER AMPLIFIED PATTERN OF RIDGING ALOFT OVER THE
ROCKIES AND UPPER LEVEL TROUGHING OVER THE EASTERN CONUS WILL BE IN
PLACE. MODELS INDICATE A POTENT SHORTWAVE CLOSING OFF FRIDAY MORNING
OVER THE SOUTHERN GREAT LAKES AND DROPPING SOUTHEAST OVER THE
CAROLINAS BY SATURDAY MORNING. THIS WILL SEND A REINFORCING SHOT OF
COOLER AND DRIER AIR SOUTH TOWARD OUR CWA. THE ASSOCIATED HIGH
PRESSURE CENTER WILL DROP FROM THE NORTHERN PLAINS TO THE MID
MISSISSIPPI RIVER VALLEY BY SATURDAY MORNING. THE RESULTING PRESSURE
GRADIENT WILL LEAD TO GUSTY NORTH WINDS BY FRIDAY AFTERNOON HOLDING
AFTERNOON HIGHS IN THE 60S ACROSS OUR NORTHERN ZONES WHILE THE
SOUTHERN ZONES TOP OUT NEAR NORMAL IN THE LOWER 70S. THE PRESSURE
GRADIENT WILL RELAX FRIDAY EVENING BUT THE WIND MAY NOT TOTALLY
DECOUPLE BY MORNING AND MAINTAIN SOME MIXING. OTHERWISE...NEAR IDEAL
RADIATIVE COOLING OF OUR COOL DRY AIRMASS WILL SEND TEMPERATURES
INTO THE 30S BY MORNING. THESE WILL BE THE COOLEST TEMPERATURES OF
THE SEASON WITH PATCHY LIGHT FROST POSSIBLE OVER MUCH OF OUR AREA.
SATURDAY THE SURFACE RIDGE WILL MOVE OVER OUR CWA AS THE HIGH SHIFTS
EAST. THIS WILL RESULT IN A MUCH LIGHTER WIND THAN ON FRIDAY BUT
TEMPERATURES WILL ONLY TOP OUT IN THE 50S AT MOST SITES. THE SURFACE
HIGH WILL CONTINUE SHIFTING EAST THROUGH SUNDAY AS WELL AS RIDGING
ALOFT. THE COLDEST MORNING OF THE PERIOD IS EXPECTED SUNDAY MORNING
AS ANOTHER NIGHT OF STRONG RADIATIVE COOLING IS EXPECTED. MORNING
LOWS WILL BE BACK IN THE 30S AREAWIDE AND OUR NORMALLY COLDER
LOCATIONS MIGHT SEE FREEZING TEMPERATURES FOR THE FIRST TIME THIS
SEASON. LIGHT RETURN FLOW IS EXPECTED BY SUNDAY AFTERNOON AS THE
SURFACE HIGH BECOMES CENTERED OVER THE MID ATLANTIC SEABOARD. THE
RIDGE ALOFT WILL BECOME CENTERED OVER OUR CWA SUNDAY AFTERNOON AS
WELL. THIS WILL ALLOW TEMPERATURES TO CLIMB INTO THE 60S SUNDAY
AFTERNOON BUT NORMAL HIGHS RUN IN THE LOWER 70S. NORMAL LOWS RUN IN
THE UPPER 40S TO NEAR 50 DEGREES. BELOW NORMAL TEMPERATURES ARE

TODAY THROUGH THURSDAY

WELL ADVERTISED COLD FRONT AND ASSOCIATED RAIN/TSTORM BAND MOVING
THROUGH REGION THIS MORNING FOLLOWED BY CLEARING THIS AFTERNOON WITH
COOLER TEMPERATURES EXPECTED. NEAR TO SLIGHTLY BELOW NORMAL
TEMPERATURES EXPECTED THURSDAY WITH FULL SUNSHINE.

AS OF 08Z, COLD FRONT WAS LOCATED ALONG A TUPELO, MS TO MONROE, LA
LINE WITH A MORE POTENT LINEAR TSTORM BAND RIGHT ALONG THE BOUNDARY
OVER THE GOLDEN TRIANGLE AREA. THIS MORE ROBUST SECTION (WHERE
BETTER DIVERGENCE IS LOCATED) WILL SHIFT EAST OVER NEXT HOUR WITH
EVEN WEAKER SUPPORTED SHOWER ACTIVITY TRAILING BACK WSW ALONG AND
BEHIND THE STRUNG OUT BOUNDARY INTO THE SOUTHERN DELTA. THESE
SHOWERS OVER DELTA INTO LA WILL STRUGGLE TO MAINTAIN PERSISTENCE AS
THEY SHIFT EAST DUE TO DYNAMIC FORCING OUT PACING THE FRONT. FEEL
ISO/SCT SHOWERS THROUGH 6AM-NOON WILL BE BEST BET AND WENT WITH
20-40% FOR MOST OF REGION AND THINKING NW DELTA WILL BE CLEAR OF
PRECIP BY THAT TIME. BY THIS AFTERNOON, ONLY SOME ISO/SCT LIGHT
SHOWERS ARE EXPECTED ALONG/BEHIND FRONT AS IT PUSHES THROUGH HWY 84
CORRIDOR WITH CLEARING OCCURRING ACROSS NORTH HALF FROM BEHIND.
WINDS COULD GUST UP TO 15-20 MPH AT TIMES THIS AFTN IN DELTA BEHIND
FRONT AS CAA MIXING GETS GOING. WENT TOWARDS COOLER EC/MET MOS FOR
HIGHS TODAY GIVEN EARLY CLOUDS AND PROGGED 12-15C RAW NWP H925 TEMPS
THIS AFTERNOON DESPITE FULL SUN IN NORTH HALF.

EXPECT CLEAR SKIES ALL OF THURSDAY AND SEASONAL TEMPS IN THE UPPER
60S NORTH TO MID 70S SOUTH WITH FULL SUN WITH LIGHT COOL NORTH
WINDS. LOWS WILL ON THE CRISP SIDE; FALLING INTO THE LOW TO MID 40S
AND MODERATE A COUPLE DEGREES BY FRIDAY MORNING. /ALLEN/
