AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 305 PM CDT WED SEP 1 2010 .DISCUSSION... MAIN CONCERNS ARE POPS THROUGH FRIDAY MORNING...AND THEN ATTENTION SHIFTS TO TEMPERATURES AND DEWPOINTS FOR THE WEEKEND AND NEXT WEEK. EARLY MORNING CONVECTION HAS HELD OFF JUST NORTHWEST OF THE QUAD STATE THROUGH THE DAY. COMBINATION OF DIFFERENTIAL HEATING BOUNDARY AND PROXIMITY TO MCV OVER MISSOURI SHOULD RESULT IN SCATTERED CONVECTION OVER SOUTHEAST MISSOURI AND SOUTHERN ILLINOIS THROUGH THE AFTERNOON AND INTO THE EVENING. BELIEVE THAT THE 12Z NAM IS TOO ROBUST WITH OVERNIGHT POPS...AND LAST NIGHTS SPC WRF RUN SHOWS VERY LITTLE CONVECTION IN THIS AREA. DECIDED TO GO WITH CHANCE POPS IN THAT AREA...AND KEPT IT THROUGH THE NIGHT JUST TO BE SAFE. SOUTHEAST PORTIONS OF THE AREA WILL REMAIN DRY TONIGHT. ONCE AGAIN THE NAM APPEARS OVERDONE IN LINGERING CONVECTION OVER THE NORTHWEST HALF OF THE AREA THURSDAY...BUT CANNOT RULE IT OUT COMPLETELY...ESPECIALLY IN THE MORNING. FEEL THAT THE AFTERNOON WILL LIKELY BE DRY...AS CONVECTION REFORMS ALONG THE FRONT NORTHWEST OF THE AREA. FOR THE FRONTAL PASSAGE THURSDAY NIGHT...MODEL SIGNAL IS FOR CONVECTION TO DEVELOP/PROPAGATE SOUTHWARD THROUGH MISSOURI INTO BETTER MOISTURE OVER ARKANSAS THROUGH THE EVENING. WITH THE THERMODYNAMICS BEING EATEN UP TO OUR WEST/SOUTHWEST...PRECIPITATION OVER OUR AREA WILL BE DEPENDENT ON STRENGTH OF DYNAMIC FORCING WITH MIDWEST MID/UPPER LEVEL TROUGH. CONFIDENCE IS NOT HIGH AT ALL FOR WIDESPREAD PRECIPITATION WITH THE FRONT THURSDAY NIGHT. KNOCKED POPS BACK DOWN TO GOOD CHANCE LEVELS...WITH LOWER POPS TO THE SOUTHEAST. CANNOT RULE OUT A LINGERING CHANCE POP IN THE SOUTHEAST FRIDAY MORNING. THE MODELS ARE SPEEDING UP THE ONSET OF THE COOL...DRY AIR. LOWER 50S DEWPOINTS SHOULD OVERSPREAD THE ENTIRE AREA BY 00Z SATURDAY...AND MUCH OF THE AREA WILL STRUGGLE INTO THE LOWER 80S FOR HIGHS DESPITE PLENTY OF SUNSHINE. IN THE EXTENDED...THE CONSENSUS IS FOR SURFACE HIGH PRESSURE TO SETTLE IN JUST TO OUR SOUTH BY SUNDAY. SATURDAY WILL BE SIMILAR TO FRIDAY FOR HIGHS...BUT A WARMING TREND WILL COMMENCE FOR SUNDAY INTO NEXT WEEK...AS THE UPPER HIGH BUILDS BACK OVER THE REGION...AND THE LOW-LEVEL FLOW BECOMES SOUTHEAST. MAIN DIFFERENCE IN THE MODELS IS IN HOW DRY IT WILL STAY INTO NEXT WEEK. THE ECMWF KEEPS VERY DRY AIR OVER THE AREA...WHILE THE MEX/GFS INCREASE IT MUCH FASTER. WITH SURFACE HIGH SETTLING IN BETWEEN US AND THE GULF...FEEL THAT A DRIER SOLUTION IS PROBABLY BETTER. SHOULD SEE LARGE DIURNAL RANGES THROUGH AT LEAST THE FIRST HALF OF NEXT WEEK...WITH HIGH PRESSURE IN CONTROL AT THE SURFACE AND ALOFT. HIGH TEMPERATURES WILL CLIMB INTO 90S MONDAY THROUGH WEDNESDAY. NO SIGN OF ANY PRECIPITATION THROUGH NEXT WORK WEEK. && .AVIATION... VFR CONDITIONS EXPECTED...WITH SOME CU AND CIRRUS ACROSS THE REGION TODAY AND TONIGHT. WENT WITH CB QUALIFIERS FOR KCGI AND KPAH...AND EVEN A VCTS AT KCGI GIVEN CURRENT RADAR PICTURE. HARD TO DETERMINE AT THIS TIME HOW FAR EAST CONVECTION WILL MAKE IT FROM MISSOURI AND SOUTHWEST ILLINOIS. BUT WILL NEED TO MONITOR...DESPITE THE FACT MOST OF THE MODELS SHOW ITS EASTWARD PROGRESSION COMING TO A HALT WITH TIME. SSW WINDS AROUND 10 KTS EXPECTED TODAY WITH A FEW HIGHER GUSTS POSSIBLE. WINDS SHOULD BE LIGHT SOUTH TONIGHT. && .PAH WATCHES/WARNINGS/ADVISORIES... KY...NONE. MO...NONE. IL...NONE. IN...NONE. && PUBLIC.....DRS AVIATION...CW
