.UPDATE...
ISSUED AT 826 PM CDT WED APR 25 2012

WATCHING STORMS IN NORTHEAST MISSOURI MOVE SOUTHEAST. SPC HAS
WATCH JUST NORTH OF OUR AREA...BUT DEPENDING UPON WHAT THESE
STORMS DO...WE MAY BE UNDER A WATCH LATER TONIGHT. STILL PRETTY
UNSTABLE OVER THE REGION WITH CAPE VALUES 1000-3000 J/KG.

MADE SOME MINOR ADJUSTMENTS TO POP AND WEATHER TONIGHT AND
TOMORROW MORNING.

&&

.SHORT TERM...(THIS EVENING THROUGH SATURDAY NIGHT)
ISSUED AT 219 PM CDT WED APR 25 2012

IN ESSENCE...IT LOOKS LIKE WE ARE GOING TO BE VISITED BY A COLD
FRONT TONIGHT. HOWEVER...MUCH OF THE UPPER SUPPORT IS MOVING OF TO
THE EAST WITH CURRENT PRECIP...AND SHOULD LOSE MUCH INSTABILITY AS
THE SUN GOES DOWN. THUS...THE FRONT WILL HAVE LITTLE SUPPORT TO
PRODUCE MUCH IN THE WAY OF SCT SHOWERS OR THUNDERSTORMS OVERNIGHT.
WILL KEEP SOME SCT POPS IN THE NE AREAS ALONG THE FRONT...JUST IN
CASE.

IN ADDITION...THERE ARE NOW INDICATIONS THAT THE FLOW ALOFT WILL
REMAIN FROM THE NW A BIT LONGER IN TIME...AND THIS SHOULD SERVE
TO SHOVE THE FRONT FARTHER SOUTH INTO TN/AR FOR THU AND MUCH OF
THU NIGHT. CONSEQUENTLY...HAVE REMOVED MOST RAIN CHCS FOR ALL
EXCEPT THE FAR SOUTH AND SOUTHWEST COUNTIES OF KY/MO THU/THU
NIGHT. THIS SHOULD ALLOW TEMPS TO WARM BACK TO NEAR 80/LOWER 80S.

HOWEVER...THIS FRONT WILL EVENTUALLY ENCOUNTER SW FLOW ALOFT AHEAD
OF AN APPROACHING MID LVL SHORT WAVE ON FRI. THUS...RAIN AND
SCATTERED THUNDERSTORM CHANCES WILL INCREASE DRAMATICALLY FRI OVER
MOST THE FORECAST AREA. WITH THE LOW LVL BOUNDARY COMING NORTH
THROUGH THE AREA AND DECENT WIND FLOW ALOFT...ANY SEVERE STORM
THREAT WILL LIKELY BE HIGHLY DEPENDENT ON HOW MUCH
SUNSHINE/DESTABILIZATION CAN DEVELOP FRIDAY INTO FRI EVENING.

THE FRONT WILL CONTINUE LIFTING NORTH OF THE REGION FRIDAY NIGHT
INTO SAT...AND MAY RESULT IN ANOTHER BREAK IN APPRECIABLE
RAINS...ESP SOUTH OF RT 13 IN IL AND OVER KY. THIS FEATURE MAY
PUT AT LEAST THE SOUTH HALF OF THE FORECAST AREA IN THE WARM
SECTOR FOR AWHILE...WITH SFC DEW POINTS INTO THE 60S...BEFORE
ANOTHER COLD FRONT AND ASSOCIATED LOW PRESSURE APPROACHES FROM
THE NW LATER SAT AFTN OR SAT NIGHT. THIS SCENARIO MAY OFFER THE
HIGHEST CHANCE OF A HIGHER CHC OF OF SCT STRONG TO SEVERE
THUNDERSTORMS...BUT IS STILL WILL BE HIGHLY CONDITIONAL ON HOW
MUCH INSTABILITY CAN FORM AHEAD OF THE SYSTEM. WILL CONTINUE TO
MONITOR.

.LONG TERM...(SUNDAY THROUGH WEDNESDAY)
ISSUED AT 219 PM CDT WED APR 25 2012

VERY CHALLENGING WEATHER IN THE EXTENDED.  THE LATE WEEK/EARLY
WEEKEND FRONT WILL POSSIBLY CONTINUE TO PLAGUE US...WITH THE ECMWF
KEEPING THE FRONT HUNG UP ACROSS OUR REGION.  GFS TAKES THE FRONT
FAR ENOUGH SOUTH TO KEEP US DRY FOR A LITTLE WHILE.  HOWEVER...BASED
ON THE ECMWF...WILL KEEP SOME POPS FOR SHOWERS AND A FEW
THUNDERSTORMS ACROSS MAINLY THE SOUTHERN HALF OF THE PAH FORECAST
AREA SUNDAY AND SUNDAY NIGHT.  BASED ON THE LATEST MODEL RUNS...THE
BEST CHANCE FOR A DRY FORECAST LOOKS TO BE MONDAY INTO MONDAY
NIGHT.

BEYOND MONDAY NIGHT...CONFIDENCE DECREASES EVEN MORE...WITH BOTH
MODELS INDICATING SPORADIC CHANCES OF PRECIP THROUGH WEDNESDAY AS
UPPER LEVEL WAVES RANDOMLY SWING ACROSS THE AREA.  WENT WITH CHANCE
POPS TUESDAY INTO WEDNESDAY FOR NOW.  BELOW SEASONAL TEMPERATURES ON
SUNDAY WILL MODERATE TO NEAR SEASONAL MONDAY.  BOTH MODELS SHOW
DECENT SOUTH TO SOUTHWEST FLOW BY TUESDAY...SO RIGHT NOW IT LOOKS AS
THOUGH CONDITIONS WILL WARM TO ABOVE SEASONAL READINGS FOR TUESDAY
INTO WEDNESDAY WHETHER PRECIP CHANCES/ADDITIONAL CLOUD COVER PANS
OUT OR NOT.

&&

.AVIATION...(FOR THE 00Z TAFS THROUGH 00Z THURSDAY EVENING)
ISSUED AT 510 PM CDT WED APR 25 2012

CAP MIGRATING WEST-TO-EAST ACROSS TERMINALS IN WAKE OF FIRST MCV
RESULTING IN CLEAR SKIES AND WINDS PICKING UP OUT OF THE
SOUTH/GUSTING TO NEAR 30 KTS ACCOMPANY IT. THIS WILL CONTINUE TO
SPREAD EASTWARD ACROSS KEVV/KOWB TERMINALS EARLY THIS EVENING.
ANOTHER MCV DIVES SE IN THE PREDOMINANT FLOW AND MAY YIELD
VICINITY MENTION OF THUNDER MAINLY NORTH/EAST KEVV/KOWB LATER THIS
EVENING. WILL MONITOR CLOSELY BUT LEAVE ITS MENTION FOR NOW.
AFTERWARD VFR MID-HIGH DECKS SCATTER OUT TOWARD THE PLANNING
PERIOD AS SLYS SHIFT TO NWLYS WITH 2ND MCV PASSAGE TMRW AM.
