Area forecast discussion, Jun 20, 2:00 PM CST, 11 hours before
AREA FORECAST DISCUSSION...CORRECTED NATIONAL WEATHER SERVICE PADUCAH KY 300 PM CDT FRI JUN 20 2008 .DISCUSSION... MAIN CONCERN THIS FORECAST PACKAGE IS CHANCE FOR SHOWERS AND THUNDERSTORMS THROUGH SUNDAY...THEN AGAIN STARTING TUESDAY NIGHT. MID-LEVEL WAVE RESPONSIBLE FOR THE WIDESPREAD SHOWER AND ISOLATED THUNDERSTORM ACTIVITY TODAY CONTINUES TO PUSH EAST OF THE REGION THIS AFTERNOON. IN ITS WAKE...THE ATMOSPHERE HAS DESTABILIZED ENOUGH TO POP ADDITIONAL ISOLATED CONVECTION OVER SOUTHERN MISSOURI. TONIGHT...THE BEST CHANCE OF LINGERING ACTIVITY WILL BE FOCUSED OVER THE PENNYRILE REGION OF WESTERN KENTUCKY...TAPERING TO SLIGHT CHANCES FARTHER WEST AND NORTH. AS WAS DEMONSTRATED LAST NIGHT AND TODAY...THE ABILITY TO PINPOINT THE INDIVIDUAL PEAKS IN PRECIPITATION CHANCES WELL IN ADVANCE WILL BE DIFFICULT OVER THE NEXT WEEK. IN THE NEAR TERM...THE UPPER-LEVEL PATTERN WILL AMPLIFY OVER THE WEEKEND AS THE NEXT IN A SERIES OF SHORTWAVE TROUGHS DIVES SOUTHWARD INTO THE OHIO VALLEY ON SUNDAY. SO AFTER A SLIGHT CHANCE OF MAINLY DIURNAL CONVECTION SATURDAY...WE BUMPED UP PRECIPITATION CHANCES TO AS HIGH AS 40 PERCENT ON SUNDAY FROM MOUNT VERNON ILLINOIS TO OWENSBORO KENTUCKY...WITH LOWER CHANCES FARTHER SOUTH AND WEST. WHILE NOT ENTIRELY CERTAIN...LATEST SREF AND OPERATIONAL RUNS OF THE NAM AND GFS ARE SIGNALING BETTER ODDS OF STAYING DRY MONDAY AND MOST OF TUESDAY. AFTER THAT...ALL BETS ARE OFF AS A FAIRLY ACTIVE BUT WEAK NORTHWEST FLOW PATTERN PERSISTS. AS A RESULT...WILL MAINTAIN SMALL RAIN CHANCES THROUGH THE COURSE OF THE MIDDLE TO END OF NEXT WEEK. AS FAR AS TEMPERATURES ARE CONCERNED...NIGHTTIME LOWS REFLECT A WARMER FWC/MET BLEND OVER THE NEXT TWO NIGHTS...WITH DAYTIME HIGHS AN AVERAGE OF AVAILABLE GUIDANCE. IN THE EXTENDED...WE GENERALLY FAVORED THE GUIDANCE BASED ON THE GFS ENSEMBLE MEAN. && .AVIATION... GENERALLY VFR SKY AND VSBY CONDITIONS EXPECTED THIS AFTERNOON AND EVENING. BRIEF MVFR CIGS AND VSBYS POSSIBLE...AND WILL LIMIT CONVECTION TO VICINITY AS THE BULK OF THE SHOWERS AND ISOLD STORMS PUSHES EAST OF THE TAF SITES. OVERNIGHT...INTO THE FIRST HALF OF SATURDAY EXPECT MAINLY DRY CONDITIONS. COULD BE SOME FOG OR SCT LOW CIG RESTRICTIONS AFTER MIDNIGHT AS FORECAST SOUNDINGS SATURATE WITH SHARP BLYR INVERSION DEVELOPING AFTER 06Z BELOW 1K FT. WILL HINT AT BOTH BUT REFRAIN FROM AOB IFR RESTRICTIONS UNTIL A CLEAR SIGNAL SHOWS UP IN TRENDS OVERNIGHT. WINDS WILL NOT BE OPERATIONALLY SIGNIFICANT. && .PAH WATCHES/WARNINGS/ADVISORIES...
