AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE PADUCAH KY 625 PM CDT SAT OCT 1 2011 .UPDATE... DISCUSSION FOR 00Z SUNDAY ROUTINE TAF ISSUANCE. MONITORING SENSIBLE WEATHER TO DETERMINE WHETHER FROST ADVISORY MAY STILL BE NEEDED OR NOT LATE TONIGHT. && ...SHORT TERM /TONIGHT THROUGH MONDAY NIGHT/... /PREVIOUSLY ISSUED 228 PM CDT SAT OCT 1 2011/ VERY QUIET WEATHER PATTERN SHAPING UP FOR THE NEXT SEVERAL DAYS. DEEP MID LEVEL LOW OVER THE EASTERN STATE WILL KEEP A COOL DRY NORTHERLY FLOW IN PLACE ACROSS THE AREA THROUGH THE WEEKEND. WITH THE SURFACE HIGH PRESSURE RIDGE TO THE WEST OF THE IMMEDIATE AREA... THE NEXT COUPLE OF NIGHTS PROMISE TO BE QUITE COLD...AS LOWS DIP INTO THE UPPER 30S AND LOWER 40S. TONIGHT WILL BE THE COLDEST NIGHT AS MOST AREAS ARE FORECAST TO REACH 36 TO 39 BY DAYBREAK SUNDAY. THIS WILL BE COLD ENOUGH FOR THE FORMATION OF PATCHY FROST...MAINLY IN AREAS SHELTERED FROM THE OCCASIONAL STIR OF A LIGHT BREEZE. NOT PLANNING TO ISSUE A FROST ADVISORY AT THIS TIME. HOWEVER...THOSE IN LOW-LYING OR SHELTERED AREAS OF SOUTHERN ILLINOIS AND SOUTHEAST MISSOURI MAY WISH TO PROTECT TENDER VEGETATION TO PLAY IT SAFE FOR AT LEAST TONIGHT. THE SURFACE AND UPPER LEVEL RIDGES WILL BE SLOW TO SHIFT EAST THROUGH MONDAY NIGHT...SO ANY WARM-UP WILL BE GRADUAL EACH DAY. AFTER ONE MORE DAY IN THE 60S...TEMPERATURES SHOULD MANAGE BACK INTO THE LOWER AND MID 70S BY MONDAY AFTERNOON. GIVEN THE VERY DRY AIR IN PLACE...EXPECT A WIDE DIURNAL TEMPERATURE SWING BY AT LEAST 30 DEGREES EACH DAY. .RJP.. ...LONG TERM /TUESDAY THROUGH SATURDAY/... /PREVIOUSLY ISSUED 228 PM CDT SAT OCT 1 2011/ THE 12Z GFS AND 00Z ECMWF CONTINUE TO BE IN VERY GOOD AGREEMENT THROUGH THE PERIOD. ONLY VERY MINOR ADJUSTMENTS HAVE BEEN MADE TO THE PREVIOUS FORECAST. CANADIAN SURFACE HIGH PRESSURE WILL REMAIN OVER THE QUAD STATE AND GRADUALLY MODIFY THROUGH THE PERIOD. ALOFT...A 586 HIGH AT 500MB WILL BUILD OVER THE REGION THROUGH THURSDAY...AND THEN LINGER IN OUR VICINITY INTO THE WEEKEND. ALL IN ALL A BEAUTIFUL WEEK IS IN STORE FOR THE ENTIRE AREA. DEWPOINTS WILL GRADUALLY INCREASE THROUGH THE PERIOD...LEADING TO A TREND TOWARD MILDER NIGHTS. HIGHS LIKEWISE WILL INCREASE THROUGH THE PERIOD. TUESDAY WILL BE NEAR NORMAL WITH HIGHS IN THE MID TO UPPER 70S...AND MOST AREAS SHOULD BE IN THE LOWER 80S FOR THURSDAY THROUGH NEXT SATURDAY. REALLY PREFER THE WARMER LOW-LEVELS OF THE ECMWF AS OPPOSED TO THE GFS. COULD SEE SOME MID 80S IN A FEW LOCATIONS THURSDAY THROUGH SATURDAY. THE 12Z ECMWF JUST CAME IN AND IS BRINGING A FRONT AND A BAND OF PRECIPITATION EASTWARD INTO THE REGION THROUGH THE DAY SUNDAY. THIS IS A SIGNIFICANT CHANGE FROM ITS PREVIOUS RUN...WHICH WAS DRY THROUGH 10 DAYS. SO...WILL HAVE TO SEE IF THIS IS THE BEGINNING OF A SHIFT IN THE MODELS OR JUST A ONE CYCLE ABERRATION...SIMILAR TO THE 00Z GFS. OF COURSE...WILL NOT NEED TO ADDRESS THIS IN THE FORECAST UNTIL SUNDAY. .DRS.. && .AVIATION...
