After the clipper system on the 5th, an upslope event ensued that added some more snowfall on top of what fell on the 5th. Therefore another winter weather advisory needed to be issued.

NWS Jackson, KY wrote its last area forecast discussion before the first event at Dec 5, 7:04 PM EST, 2 hours 56 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 704 PM EST SUN DEC 5 2010 .SHORT TERM.../THE REST OF TODAY/...UPDATED A BAND OF SNOW SHOWERS HAS MOVED ACROSS EASTERN KENTUCKY AND IS NOW EXITING INTO VIRGINIA. SOME ISOLATED TO SCATTERED SHOWERS SHOULD TAPER TO FLURRIES BETWEEN 8 AND 9 PM...HOWEVER THE WORST OF SNOW SHOWERS SHOULD NOW BE OVER. WILL UPDATE THE ZONE FORECASTS BETWEEN 8 AND 9PM. THE PREVIOUS SHORT TERM FORECAST DISCUSSION FOLLOWS... /TONIGHT THROUGH TUESDAY NIGHT/ DEEP MID AND UPPER LEVEL CYCLONIC FLOW CONTINUES TO DOMINATE ACROSS KENTUCKY THIS AFTERNOON. THIS HAS KEPT THE WEATHER CLOUDY AND UNSETTLED WITH PERIODS OF LIGHT SNOW SHOWERS AND FLURRIES. LATEST SATELLITE IMAGE SHOWING SOME CLEARING NOW WORKING SOUTHEASTWARD ACROSS CENTRAL ILLINOIS. THIS CLEARING IS PEGGED TO REACH OUR SOUTHWEST ZONES SHORTLY AFTER MIDNIGHT. MEANWHILE...NORTHWEST FLOW INTO THE HIGHER TERRAIN OF EASTERN KENTUCKY HAS HELPED TO GENERATE MORE WIDESPREAD SNOW SHOWER ACTIVITY. AT THIS POINT...MAINLY LIGHT SNOWFALL IS BEING OBSERVED BASED ON AREA WEBCAMS. HOWEVER...A MORE ROBUST AREA OF SNOW SHOWERS...ORIGINATING FROM SOUTHERN LAKE MICHIGAN (LAKE EFFECT)...WILL PUSH SOUTH INTO OUR CENTRAL AND NORTHEAST ZONES INTO THE EVENING HOURS. AS THIS AREA OF SNOW SHOWERS MOVE IN...MODEL SOUNDINGS SHOW SATURATION UP TO AROUND -15C...WITH THE POTENTIAL FOR MORE DENDRITIC SNOWFLAKE GROWTH. THUS...THERE WILL BE A SHORT PERIOD OF MORE MODERATE SNOW THIS EVENING. WE COULD SEE SOME LOCAL LIGHT SNOW ACCUMULATIONS UP TO A HALF INCH THIS EVENING. BY LATER TONIGHT...THE AFOREMENTIONED CLEARING WILL SHIFT INTO OUR SOUTHWEST ZONES...WITH THE CLOUD COVER MORE CONFINED TO THE NORTHEAST. MOISTURE WILL BEGIN TO STRIP OUT BY LATE THIS EVENING...SO ONLY EXPECTING SOME FLURRIES FOR THE SECOND HALF OF THE NIGHT. TOMORROW/TOMORROW NIGHT...ANOTHER SHORT WAVE WILL DROP ACROSS EASTERN KENTUCKY WITH CLOUDS INCREASING ACROSS THE AREAS THAT MANAGE TO LOSE THE CLOUDS TONIGHT. ALSO...MOISTURE WILL ONCE AGAIN INCREASE TO AROUND -15C...WITH ANOTHER ROUND OF LIGHT SNOW SHOWER ACTIVITY EXPECTED. AGAIN...ANY ACCUMULATIONS WILL REMAIN LIGHT. TUESDAY AND TUESDAY NIGHT...CLOUDS WILL SLOWLY RETREAT TO THE NORTHEAST...WITH CLEARING FINALLY OCCURRING TUESDAY NIGHT. JUST EXPECTING FLURRIES THROUGH THIS PERIOD...BUT WOULD NOT BE SURPRISED TO SEE ANOTHER ROUND OF LIGHT SNOW SOMEWHERE IN THIS TIME FRAME. AS FAR AS TEMPERATURES ARE CONCERNED...CERTAINLY GOING TO BE COLD OVER THE NEXT SEVERAL DAYS. NOT MANY CHANGES MADE TO TEMPERATURES AS THEY WILL BE HIGHLY DEPENDENT ON CLOUD COVER. AS OF RIGHT NOW...FOLLOWING GUIDANCE FAIRLY CLOSELY...BUT IF THINGS CLEAR OUT TONIGHT THROUGH TUESDAY NIGHT WE COULD END UP COOLER THAN GUIDANCE. SAME HOLDS FOR HIGHS. IF SKIES CLEAR DURING THE DAYTIME...HIGHS MAY CLIMB ABOVE GUIDANCE. .LONG TERM.../WEDNESDAY THROUGH SUNDAY/ MODELS ARE IN GENERAL AGREEMENT UNTIL THE WEEKEND. A SURFACE HIGH PRESSURE RIDGE SHOULD BRING QUIET WEATHER TO START THE PERIOD. A VERY COLD AIR MASS WILL BE IN PLACE...BUT A CUTOFF TO COLD AIR ADVECTION AND AT LEAST SOME LIMITED SUN SHOULD BRING MODERATING TEMPERATURES. A LARGE STORM SYSTEM CROSSING EAST OVER THE GREAT LAKES ON THURSDAY NIGHT INTO FRIDAY WILL BRING WARM AIR ADVECTION AND A POSSIBILITY OF PRECIP. IT WILL NOT BE ABLE TO TAP GULF OF MEXICO MOISTURE...AND ANY PRECIP LOCALLY SHOULD BE LIMITED. THE COLD FRONT ASSOCIATED WITH THE SYSTEM IS EXPECTED TO PASS ON FRIDAY. ON FRIDAY NIGHT...COLD AIR ADVECTION AND NW UPSLOPE FLOW WILL PRESENT A CONTINUING POSSIBILITY OF LIGHT PRECIP. IN TERMS OF PRECIP TYPE...BOTH RAIN AND SNOW WILL BE POSSIBLE EACH PERIOD THURSDAY NIGHT THROUGH FRIDAY NIGHT. HIGH PRESSURE BUILDING IN FROM THE WEST LOOKS TO PROVIDE A BREAK IN THE WEATHER FOR SATURDAY BEFORE THINGS MAY GET ACTIVE AGAIN. DURING THE WEEKEND THE MODELS ARE SHOWING A LOT OF DISPARITY. MODELS IN GENERAL ARE SHOWING STORM SYSTEM DEVELOPMENT OVER THE OHIO VALLEY AND TENNESSEE VALLEY REGION. HOWEVER...THERE IS DISAGREEMENT ON TRACK...TIMING...AND STRENGTH. SOME MODEL RUNS SHOW POTENTIAL FOR A VERY STRONG SYSTEM. HOWEVER...WITH SO MUCH MODEL VARIABILITY...THERE IS LOW CONFIDENCE IN THE FORECAST. AS RESULT...TEMPS COULD VARY GREATLY FROM WHAT IS BEING FORECAST. && .AVIATION.../18Z TO 18Z/ A BAND OF SNOW SHOWERS HAS MOVED ACROSS EASTERN KENTUCKY AND IS NOW EXITING INTO VIRGINIA. SOME ISOLATED TO SCATTERED SHOWERS SHOULD TAPER TO FLURRIES BETWEEN 8 AND 9 PM...HOWEVER THE WORST OF SNOW SHOWERS SHOULD NOW BE OVER. THE CIGS SHOULD BE UP AND DOWN A BIT BETWEEN MVFR AND VFR AS THERE WILL BE SOME PATCHES OF LOWER STRATO CU MOVING ACROSS THE AREA. IT WILL BE PREDOMINANT VFR UNTIL AROUND 16Z WHEN ANOTHER TROUGH SHOULD BE MOVING ACROSS THE AREA BRINGING ANOTHER ROUND OF ISOLATED TO SCATTERED SNOW SHOWERS. && .JKL WATCHES/WARNINGS/ADVISORIES...NONE. && SHORT TERM...KAS/JJ LONG TERM....HAL AVIATION...JJ
