Area forecast discussion, Apr 21, 2:27 PM CDT, 5 hours 7 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 225 PM WED APR 21 2004 .DISCUSSION... MAIN CONCERN FOR THE FORECAST CONTINUES TO BE POPS AND SEVERE WEATHER CHANCES THROUGH THE REST OF THE WEEK. A BAND OF SCATTERED SHOWERS AND THUNDERSTORMS OVER THE SOUTHEAST THIRD OF THE CWA ASSOCIATED WITH A SHORT WAVE WILL CONTINUE TO MAKE SLOW PROGRESS TO THE EAST. IN THE MEANTIME...NEARLY STATIONARY COLD FRONT REMAINS POISED JUST TO THE NORTHWEST OF THE CWA. OVER THE PAST COUPLE OF HOURS SKIES HAVE CLEARED OVER THE NORTHWEST HALF OF THE CWA CAUSING THE AIRMASS IN THOSE AREAS TO DESTABILIZE NICELY. LATEST LAPS DATA SHOWING LIFTED INDICES IN THE -6 TO -10 RANGE AND CAPE RANGING FROM 500 TO 1800 J/KG. LATEST SAT PIX SHOWING SOME TCU DEVELOPMENT ALREADY. WILL HAVE TO MONITOR CLOSELY. FORECAST-WISE...MODELS AGAIN NOT IN THE BEST AGREEMENT. GFS APPEARED TO AGAIN HAVE A CONVECTIVE FEEDBACK PROBLEM...SO DECIDED TO GO WITH THE ETA/MESOETA...ESPECIALLY THE MESOETA. MESOETA SAGS THE COLD FRONT INTO THE NORTHERN SECTIONS OF THE CWA LATE THIS AFTERNOON AND KEEPS IT THERE. IT THEN DEVELOPS A BAND OF CONVECTION ALONG AND JUST AHEAD OF THE BOUNDARY. BY MIDNIGHT A STRONG SHORT WAVE WILL BEGIN TO LIFT ENE ACROSS THE REGION FROM THE SOUTHERN PLAINS. THIS FEATURE...COMBINED WITH ABUNDANT LOW LEVEL MOISTURE AND THE STATIONARY BOUNDARY... SHOULD PRODUCE A ROUND OF SHOWERS AND THUNDERSTORMS BETWEEN MIDNIGHT AND MIDDAY THURSDAY. DONT EXPECT ANY FLOODING PROBLEMS WITH THIS ROUND...BUT SHOULD WET THINGS DOWN NICELY. BY LATE THURSDAY AFTERNOON AFTER THIS ROUND OF PRECIP LIFTS TO THE NORTH...THE MESOETA DEVELOPS A BAND OF RW/TRW ALONG AND JUST SOUTH OF THE BOUNDARY. THE MESOETA THEN SLOWLY DROPS THE FRONT SOUTHWARD UNTIL IT CLEARS THE CWA BY LATE FRIDAY AFTERNOON. DURING THAT 24 HOUR TIME FRAME WITH SEVERAL SHORT WAVES PASSING OVER THE BOUNDARY COMBINED WITH COPIUS AMOUNTS OF MOISTURE...IT CRANKS OUT SOME SERIOUS QPF (1 TO 3 INCHES) ACROSS THE CWA. AFTER A VERY BRIEF RESPITE...SATURDAY NIGHT THE MODELS DEVELOP A WAVE ON THE FRONT IN RESPONSE TO A SHORT WAVE LIFTING NE OUT OF THE SOUTHERN PLAINS. MODELS LIFT THE BULK OF THE ENERGY/MOISTURE TO THE NORTH AND WEST OF OUR CWA...BUT WE WILL PROBABLY SEE PRECIP...ESPECIALLY OVER THE WESTERN SECTIONS. ON SATURDAY NIGHT INTO SUNDAY MORNING THE SFC LOW...BY THEN NORTH OF THE CWA...WILL PUSH A COLD FRONT ACROSS THE AREA THUS PRODUCING ANOTHER ROUND OF RW/TRW. IN THE WAKE OF THIS SYSTEM...HIGH PRESSURE SHOULD KEEP THE AREA DRY THROUGH WEDNESDAY. FOR TEMPS...SPLIT THE DIFFERENCE BETWEEN MAV AND FWC MOS. && .PAH WATCHES/WARNINGS/ADVISORIES... IL...NONE.
