Area forecast discussion, Apr 25, 8:36 PM CDT, 6 hours 16 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 836 PM CDT WED APR 25 2012 .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. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...NONE. MO...NONE. IN...NONE.
