The episode as NWS PAH wrote it up.

Paducah, KY recorded exactly 10 inches for the month of November, which was the third highest total on record for November. The monthly total at Evansville, IN was 8.32 inches, making it the fourth wettest November. A couple of rivers in southern Illinois went above flood stage by the end of the month.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE PADUCAH KY 500 AM CST MON NOV 28 2011 .UPDATE... FOR AVIATION SECTION ONLY. && .DISCUSSION... MAIN ISSUES CONTINUE TO BE POPS AND PRECIPITATION TYPE THROUGH TUESDAY NIGHT. HAD SOME SNOW...VERY LARGE FLAKES...REACHING THE GROUND IN THE VICINITY OF THE PENNYRILE PARKWAY LATE LAST EVENING AND EARLY THIS MORNING. MODEL SOUNDINGS INDICATED OMEGA WAS MAXIMIZED NEAR THE DENDRITIC GROWTH REGION...AND THE SOUNDING WAS TOTALLY SATURATED. THE SOUNDING WAS NEAR ISOTHERMAL NEAR THE FREEZING LINE FROM 800MB DOWN TO NEAR 950MB. THIS ALLOWED SNOW TO REACH THE GROUND DESPITE TEMPERATURES INITIALLY IN THE UPPER 30S. THE TEMPERATURES ACTUALLY DROPPED INTO THE 33 TO 35 RANGE WHERE MINOR ACCUMULATIONS OCCURRED ON GRASSY SURFACES. ALL MODELS INDICATE THAT THE LOW-LEVELS OF THE SOUNDING SHOULD BE WARMING IN THAT AREA...AND RECENT RADAR TRENDS NO LONGER SHOW THE ENHANCED ECHOES ASSOCIATED WITH THE WET SNOWFALL. THE MODELS INDICATE THAT MUCH OF THE AREA WILL NOT BE SATURATED UP TO ICE NUCLEATION LEVELS THIS MORNING...SO A LIGHT RAIN/DRIZZLE IS TO BE EXPECTED. RECENT KPAH REFLECTIVITY LOOP SUPPORTS THIS IDEA. THIS LIGHT PRECIPITATION IS MEASURING...SO JACKED POPS UP TO NEAR 100 OVER MUCH OF WEST KENTUCKY THIS MORNING...WITH A SHARP GRADIENT TO THE NORTHWEST. HAVE LIKELY OR BETTER POPS THROUGHOUT THE AREA THIS AFTERNOON...AS THE DEEPER DEFORMATION ZONE FORCING CRANKS UP. THE LOW-LEVELS WILL WARM UP WITH EASTERLY LOW-LEVEL FLOW TODAY AND THIS EVENING...SO WOULD EXPECT ALL RAIN THEN. ADJUSTED POPS LATE TONIGHT AND TUESDAY MORNING TO INDICATE A DRY SLOT IMPACTING THE PENNYRILE REGION OF WEST KENTUCKY. ALL OF THE MODELS WERE SUPPORTING THIS DRYING IN OUR SOUTHEAST ZONES. NOW HAVE ONLY CHANCE POPS IN THAT AREA LATE TONIGHT AND TUESDAY MORNING. MODEL SOUNDINGS IN THE PURCHASE AREA INDICATE COOLING LATE TONIGHT AND TUESDAY...WITH GENERAL CHARACTERISTICS SIMILAR TO WHAT HAPPENED EARLIER IN THE PENNYRILE. WOULD NOT BE AT ALL SURPRISED TO SEE A CHANGE OVER TO SNOW EARLY TUESDAY MORNING ALONG THE TENNESSEE BORDER. THE CHANGE OVER WILL BE POSSIBLE GENERALLY EAST OF THE MISSISSIPPI RIVER TUESDAY AFTERNOON...AND ANY LINGERING PRECIPITATION TUESDAY NIGHT SHOULD BE ALL SNOW. FINALLY FEELING CONFIDENT ABOUT SNOW DEVELOPING...BUT SURFACE TEMPERATURES...ARE NOT EXPECTED TO FALL BELOW FREEZING UNTIL THE PRECIPITATION GETS OUT OF THE AREA TUESDAY NIGHT. HOWEVER...AS WAS THE CASE EARLIER THIS MORNING...WHERE THE SNOW FALLS HARD ENOUGH IT WILL LOCALLY TAKE TEMPERATURES DOWN TO NEAR THE FREEZING MARK...POTENTIALLY ALLOWING FOR SOME MINOR ACCUMULATIONS ON GRASSY SURFACES. THERE IS A LOT THAT HAS TO HAPPEN HERE FOR ANY SIGNIFICANT ACCUMULATIONS...SO HAVE NOT INTRODUCED ANY IN THE OFFICIAL FORECAST AT THIS TIME. AS WE FOUND OUT LAST WINTER...DEFORMATION ZONE SNOWS CAN DEVELOP AND ACCUMULATE QUICKLY...SO THIS SHOULD BE WATCHED VERY CLOSELY. LITTLE CHANGE IN THE EXTENDED...A RE-INFORCING SURFACE HIGH WILL SURGE ACROSS THE AREA THURSDAY NIGHT INTO FRIDAY...AND WARM ADVECTION WILL QUICKLY DEVELOP ON THE BACK SIDE OF THE HIGH SATURDAY NIGHT INTO SUNDAY. IT APPEARS THAT THE PRECIPITATION WOULD FALL AS RAIN...BUT SURFACE TEMPERATURES COULD BE AT OR BELOW FREEZING...SO INDICATED A WINTRY MIX SATURDAY NIGHT IN THE NORTHEAST WHERE LOW TEMPERATURES ARE FORECAST TO BE AT OR BELOW FREEZING. ANY WINTRY PRECIPITATION LATE NEXT WEEKEND WILL BE SHORT-LIVED...WITH CONTINUED WARM ADVECTION EXPECTED. && .AVIATION... LIGHT RAIN WILL PERSIST THROUGH THE PERIOD AND INCREASE WITH INTENSITY AS WE PROGRESS THROUGH THE VALID TIME OF THE TAFS. TEETERING AROUND THE LOW END MVFR AND HIGH END IFR THROUGH MOST OF THE DAY BUT EXPECT MAINLY IFR AFTER DARK. GUSTY NORTH WIND SHOULD PERSIST AS WELL WITH TIGHTENING GRADIENT AS THE LOW APPROACHES. && .PAH WATCHES/WARNINGS/ADVISORIES... KY...NONE. MO...NONE. IL...NONE.
