AREA FORECAST DISCUSSION...UPDATED AVIATION
NATIONAL WEATHER SERVICE ST LOUIS MO
1109 PM CST WED NOV 24 2010

.DISCUSSION...
/357 PM CST WED NOV 24 2010/

POWERFUL UPPER LOW/POSITIVELY TILTED TROF CURRENTLY CENTERED FROM
THE NORTHERN ROCKIES INTO THE SWRN U.S. WILL STRENGTHEN AND PROGRESS
EASTWARD THROUGH THE CENTRAL U.S. OVER THE NEXT 36H...MOVING INTO
THE EASTERN U.S. BY SATURDAY. LOTS HAPPENING WITHIN THAT NEXT 36H AS
THE ATTENDANT SURFACE FRONTAL SYSTEMS AND SURFACE LOW PROGESS INTO
AND THROUGH THE MIDDLE MS VALLEY REGION. MAIN ISSUES AND SEVERE
WEATHER AND HEAVY RAIN/FLOODING THREAT TONIGHT AND WINTRY
PRECIPITATION ON THANKSGIVING.

SIGNIFICANT MOISTURE TRANSPORT...MOISTURE CONVERGENCE/LIFT AND WAA
VIA A STOUT SWLY LLJ...RESULTED IN WIDESPREAD ELEVATED SHOWERS AND
THUNDERSTORMS ACROSS THE AREA TODAY...TO THE NORTH OF A WARM FRONT
DRAPPED TO OUR SOUTH. WE'VE ALREADY SEEN SOME FAIRLY IMPRESSIVE
DAILY RAINFALL TOTALS THUS FAR WITH A GENERAL 1.5 TO 3.0 INCHES
ALONG AND SOUTH OF A JEFFERSON CITY TO LITCHFIELD LINE. THIS
RAINFALL HAS PRODUCED QUITE A BIT OF STANDING WATER. ALL OF THIS
PRECIPITATION HAS PUSHED TO THE EAST AND NOW WE AWAIT THE NEXT ROUND
AS THE SURFACE LOW NOW CENTERED IN NE KS AND ATTENDANT STRONG COLD
FRONT MOVE EASTWARD THROUGH MO THIS EVENING. THE WARM FRONT WHICH
IS AS EQUALLY IMPRESSIVE AS THE COLD FRONT HAS LIFTED NORTHWARD IN
SW MO...WHERE THE WARM SECTOR HAS BECOME QUITE UNSTABLE AND DEEP
LAYER SHEAR IS QUITE STRONG. SUPERCELLS HAVE ALREADY BEEN NOTED
FROM SW MO INTO FAR SE KS. CONSENSUS OF THE MODEL SUITE IS THAT
THE SURFACE LOW WILL MOVE TO NEAR STL BY 06Z WITH THE WARM FRONT
LIFTING NORTHWARD THRU SE MO AND SRN IL AND VERY COLD AIR SURGING
INTO THE AREA IN THE WAKE OF THE ATTENDANT COLD FRONT. INSTABILITY
IS EXPECTED TO WANE SOME AS THE EVENING PROGRESSES AND THE WARM
SECTOR EXPANDS BUT IMPRESSIVE SHEAR AND STRONG LIFT ARE EXPECTED
TO MAINTAIN A SEVERE THREAT ALONG AND SOUTH OF THE WARM FRONT
THROUGH AT LEAST MIDNIGHT. OTHERWISE EXPECTING CONVECTION THIS
EVENING AND OVERNIGHT TO BECOME FAIRLY WIDESPREAD AGAIN...OWING
TO A SUBTLE SHORTWAVE TRACKING IN THE SW FLOW ALOFT...A BROAD 50+
KT SWLY LLJ AND THE ULJ JET EXIT REGION. FORCING ASSOCIATED WITH
THESE FEATURES IS JUXTAPOSED ALONG A ENE-WSW AXIS SPANNING THE
RETREATING WARM FRONT AND SURGING COLD FRONT AND ARE SUGGESTIVE OF
POTENTIAL FOR ADDITIONAL TRAINING THUNDERSTORMS AND LOCALLY HEAVY
RAIN. GIVEN THE RAIN THAT HAS ALREADY FALLEN AND POTENTIAL FOR
ANOTHER 1-3 INCHES WILL ISSUE A FLASH FLOOD WATCH FOR PORTIONS OF
SE AND EAST CENTRAL MO AND SW IL TONIGHT. THE WATCH WILL CONTINUE
ON THANKSGIVING MORNING FOR A SMALLER PORTION OF SW IL AND SE MO
ALONG AND JUST NORTH OF THE FRONT WHERE THE GREATEST RAINFALL IS
EXPECTED AND THERE WILL BE A THREAT OF ELEVATED THUNDERSTORMS.

THE NEXT ISSUE IS POTENTIAL FOR ANY WINTRY PRECIPITATON. TONIGHT THE
COLD SUB-FREEZING SURFACE AIR IN THE WAKE OF THE COLD FRONT WILL BE
CHASING THE NORTHERN EDGE OF THE PRECIPITATION SHIELD...WITH THE
MAJORITY OF PRECIPITATION BY/AFTER 12Z THURSDAY EXPECTED TO BE
ACROSS SE AND EAST CENTRAL MO INTO SW IL. THE PRECIPITATION IN THIS
AREA IS EXPECTED TO PERSIST AND EXPAND A BIT IN ASSOCIATION WITH AN
ADDITIONAL WEAK IMPULSE IN THE SW FLOW ALOFT AND STRONG
FRONTOGENETICAL FORCING. MEANWHILE STRONG CAA WILL BE OCCURING
ACROSS THE AREA AND THE SUB-FREEZING AIR WILL BEGIN TO UNDERCUT
THE RAIN SHIELD AS THE MORNING PROGRESSES AND INTO THE AFTERNOON.
TEMPERATURES WILL CERTAINLY BE FALLING THROUGH THE DAY BUT THERE
IS ALOT OF UNCERTAINTY HOW MUCH PRECIPITATION WILL PERSIST AS THE
FREEZING AIR SPREADS SOUTHEAST. I THINK WE WILL SEE SOME FREEZING
RAIN OVER THE SOUTHEAST THIRD OF THE CWA...BUT GIVEN THE AMOUNT OF
RAIN WE'VE HAD AND THE GROUND TEMPS...I DON'T THINK ICE ACCUMS
WILL BE MUCH ATTM AND MAY AMOUNT TO NO MORE THAN SOME LIGHT GLAZE
ON ELEVATED SURFACES. THE COLD AIR MAY DEEPEN ENUF TO SUPPORT A
LITTLE SLEET OR SNOW ACROSS FAR SE MO AND SRN IL BEFORE ALL ENDS
THURSDAY EVENING...BUT CONFIDENCE ON TIMING AND MEASURABLE AMOUNTS
IS LOW. I HAVE LEFT THE FORECAST FREE OF ANY ADVISORIES FOR WINTRY
PRECIPITATION...BUT IT IS CERTAINLY PLAUSIBLE THAT SOME MAY BE
NEEDED FOR MINOR ICE ACCUMS BEFORE ALL IS SAID AND DONE WHEN WE
CAN GET A BETTER HANDLE ON THE JUXAPOSITION OF THE RAIN SHIELD AND
SUB-FREEZING AIR.

IN THE EXTENDED...A PROGRESSIVE AND AMPLIFIED FLOW REGIME WILL
PERSIST INTO NEXT WEEK WITH ANOTHER GOOD CHANCE OF RAIN IN THE LATE
MONDAY-TUESDAY TIME FRAME.

.AVIATION...
/1037 PM CST WED NOV 24 2010/

WRMFNT HAS JUST GONE N OF STL/SUS WITH A SWLY SFC WIND. THIS
WRMFNT EXTENDS E OF A WEAK SFC LOW BETWEEN COU AND STL. A
CDFNT/INVERTED SFC TROF EXTENDS N OF THIS LOW TO UIN...AND A
CDFNT EXTDS SW OF THIS LOW THROUGH SGF. THE SFC WIND WILL PICK UP
FROM A NWLY DIRECTION IN UIN AND COU LATE TGT AS A STRONG RIDGE
BUILDS SEWD INTO MO BEHIND THE CDFNT. SWLY SFC WIND AT STL/SUS
WILL VEER AROUND TO A NWLY DIRECTION BY 09Z THU AND STRENGTHEN.
THE VSBYS WILL IMPROVE AT UIN AND COU LATE TGT AS THE SFC WIND
PICKS UP. THE LOW LEVEL STRATUS CLOUDS SHOULD VERY SLOWLY RISE
ESPECIALLY AFTER SUNRISE WITH VFR CONDITIONS BY LATE MRNG.
SHOWERS/STORMS SHOULD CONTINUE IN STL/SUS FOR MUCH OF THE LATE NGT
HOURS...THEN TAPER OFF TO LIGHT RAIN BY MRNG. THERE IS A
POSSIBILITY OF LIGHT FREEZING RAIN...SLEET OR SNOW THU AFTN AS THE
COLD AIR FILTERS INTO THE AREA BEHIND THE CDFNT BUT WILL LEAVE OUT
OF THE STL/SUS TAFS AS THE PROBABILITY IS LOW. THE CIG/VSBY IN
STL/SUS SHOULD IMPROVE TO THE VFR CATAGORY THU AFTN.

SPECIFICS FOR KSTL...SHOWERS SHOULD CONTINUE AT STL FOR MUCH OF
THE LATE NGT ALTHOUGH THE THUNDERSTORMS MAY SHIFT SE OF STL
TOWARDS MRNG. THE SWLY SFC WIND WILL VEER AROUND TO A NWLY
DIRECTION BY 09Z THU THEN INCREASE TO AROUND 12-13 KTS BY 12Z THU
WITH SOME GUSTS. THERE WILL BE VARIABILITY IN THE CIG HEIGHTS AND
VSBYS LATE TGT WITH THE SHOWERS/STORMS MOVING THROUGH STL...BUT
THERE MAY BE SOME DETERIORATION LATE TGT/EARLY THU MRNG AFTER THE
INTENSITY OF THE RAINFALL DECREASES AND BEFORE THE SFC WIND PICKS
UP. THERE WILL BE A GRADUAL RISE IN THE CEILING HEIGHT AND
IMPROVEMENT IN THE VSBY THU MRNG...WITH VFR CONDITIONS THU AFTN.
THE NWLY SFC WIND WILL WEAKEN THU NGT WITH A CLEARING SKY.

A STRONG STORM SYSTEM AND COLD FRONT WILL MOVE THROUGH THE MIDDLE
MISSISSIPPI VALLEY TONIGHT THROUGH EARLY THANKSGIVING DAY.
THUNDERSTORMS ARE EXPECTED ALONG AND AHEAD OF THE SYSTEM. SOME OF
