The episode as NWS JKL wrote it up.
On December 21st, warm air advection ahead of a low pressure system in Plains created light but troublesome freezing precipitation over the Tennessee valley and into eastern Kentucky. The event resulted in continued freezing drizzle and snow resulting in a thin glaze of ice.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Jackson, KY wrote its last area forecast discussion before the first event at Dec 20, 7:18 PM EST, 1 hour 42 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON KY 718 PM EST MON DEC 20 2010 .SHORT TERM.../TONIGHT AND EARLY WEDNESDAY/...UPDATED A BAND OF PRECIP IS STREAKING TOWARD US FROM THE NORTHWEST. INITIALLY THIS WILL FALL AS VIRGA...HOWEVER SNOW IS REACHING THE GROUND AT SDF AS OF 01Z. RECENT RUNS OF THE HRRR SEEM TO HAVE A GOOD HANDLE ON THE EVOLUTION OF THIS BAND OF PRECIP AND WILL UPDATE THE FORECAST TONIGHT BASED LARGELY ON THIS MODEL. THE UPDATED FORECAST WILL FEATURE PRECIP BEGINNING OVER OUR NORTHEAST BLUEGRASS COUNTIES IN A COUPLE HOURS...THEN SPREADING SOUTHEASTWARD WITH CATEGORICAL POPS NORTH OF JKL AFTER MIDNIGHT. POPS WILL TAPER TO THE HIGH CHANCE RANGE SOUTH TO THE TN BORDER. P-TYPE SHOULD INITIALLY BE SNOW BUT WILL GRADUALLY CHANGE OVER TO RAIN OVERNIGHT AND EARLY TUESDAY MORNING FROM SOUTHWEST TO NORTHEAST AS TEMPS WARM ABOVE THE SURFACE. A BRIEF PERIOD OF FREEZING RAIN AND/OR SLEET IS POSSIBLE DURING THIS TRANSITION. WE EXPECT UP TO AN INCH OF SNOW NORTH OF JKL...INCLUDING THE MOUNTAIN PARKWAY AND I-64...WITH LITTLE TO NO SNOW ACCUMULATION TO THE SOUTH OF JKL. STILL UNCERTAIN ABOUT THE ICE IMPACT...SO WILL KEEP WITH JUST A CHANCE OF FREEZING RAIN AND CONTINUE OUR SPECIAL WEATHER STATEMENT. AN ADVISORY MAY INDEED BE NEEDED ONCE THE AMOUNT AND PLACEMENT OF ANY FREEZING RAIN BECOMES MORE CLEAR. UPDATED FORECAST WILL BE SENT BY 8 PM... THE PREVIOUS SHORT TERM FORECAST DISCUSSION FOLLOWS... /TONIGHT THROUGH WEDNESDAY NIGHT/ PUT OUT AN UPDATE A SHORT WHILE AGO TO ADD A WINTRY MIX TO THE FORECAST FOR TONIGHT AND TOMORROW. THE REASON FOR THE WINTRY MIX IS THAT THE CLOUD TOPS FOR THE LOWER LEVELS TOP OFF AT AROUND -8 AFTER AROUND 2-3 AM. THIS WILL NOT ALLOW FOR THE CLOUDS TO GET INTO THE DENDRITIC GROWTH REGION...SO THE PRECIPITATION THAT WILL FALL WILL BE EITHER DRIZZLE OR AT BEST SOME SNOW GRAINS. THIS SYSTEM IS IN GENERAL FAIRLY WEAK...SO I AM NOT EXPECTING MUCH ACCUMULATION AT ALL DURING THE MIXED PRECIPITATION EVENT. THE BEST CHANCE FOR ACTUALLY GETTING MEASURABLE RAIN WILL BE IN THE AFTERNOON AFTER THE TEMPERATURES GET ABOVE FREEZING. THE FREEZING PRECIPITATION SHOULD BE JUST ENOUGH TO CREATE A REAL NUISANCE FOR UNTREATED ROADWAYS AND BRIDGES. ON TUESDAY NIGHT...THERE WILL BE ANOTHER CHANCE FOR SOME FREEZING DRIZZLE ON THE BACK SIDE OF THE CLIPPER SYSTEM AS THE CLOUD TOPS ARE IN THE -6 TO -8 RANGE. THIS ONCE AGAIN WILL BE A VERY MINOR EVENT AS FAR AS ICE ACCUMULATION...BUT COULD CAUSE SLIPPERY ROADS. RELIED MOSTLY ON THE NAM FOR THE SHORT TERM FORECAST...INCLUDING THE TEMPERATURES. .LONG TERM.../THURSDAY THROUGH MONDAY/ THE FORECAST BEGINS ON THURSDAY WITH QUITE A BUSY LONG TERM FORECAST IN STORE FOR EASTERN KENTUCKY. ON THURSDAY...THE UPPER LEVEL PATTERN IS IN A RIDGE OVER THE WEST AND TROUGH OVER THE EAST TYPE PATTERN. UPPER LEVELS HINT AT A NORTHERN STREAM AND SOUTHERN AS WELL AND THESE SHOW THE POSSIBILITY OS SHARING ENERGY AND WILL BECOME BIG PLAYERS IN A POTENTIALLY MAJOR WINTER STORM FOR CHRISTMAS EVE AND INTO CHRISTMAS DAY. OVERALL FOR THE SYSTEM...PREVIOUS MODEL RUNS HAVE BEEN FAIRLY AGREEABLE. HOWEVER...THERE HAVE BEEN AND CONTINUE TO BE SLIGHT DIFFERENCES IN THE TRENDS. 12Z RUNS FOR THE GFS...EC...AND GEM HAVE ALL TAKEN A JAUNT SOUTH WITH THE SYSTEM. THE MOST RECENT RUN OF THE EURO HAS TAKEN A SIGNIFICANT TURN SOUTH WITH THE QPF BULLSEYE GOING SOUTH WITH IT MAKING THE THREAT OF HEAVY SNOW NOT VERY LIKELY GIVEN PREVIOUS RUNS AND WHAT THE RUNS HAVE SHOWN PREVIOUSLY...WILL CONTINUE TO PROVIDE STRONG WORDING BUT WILL HOLD OFF ON A ACTUAL NUMBER OF SNOWFALL. IN NORTHWEST FLOW FOR THURSDAY AND A WEAK DISTURBANCE OVERHEAD WILL KEEP THE CHANCE FOR FLURRIES INTO THE ONSET OF THE STORM ON FRIDAY. MODELS AGREE ON WARM FRONT PRECIP TO START OUT AND THE POSSIBILITY OF WARM AIR INTRUDING...THERE MAY BE A BRIEF MIX OF SLEET AND FREEZING RAIN. THE MODELS HAVE HOWEVER TRENDED COLDER AND WITH THIS CONTINUATION...THERE MAY BE NO CHANGE OVER TO RAIN AND JUST STAY ALL SNOW. CONCERNING THE SYSTEM FRIDAY INTO SATURDAY...THE LASTED RUN OF THE EURO PAINTS A NOT SO GLOOM PICTURE WITH THE HEAVIEST QPF SOUTH OF THE KY/TN BORDER. THE UPPER LEVELS DONT REALLY SEE A PHASE NOW UNTIL SUNDAY 00Z AFTER THE MAIN LOW HAS CROSSED THE APPALACHIANS SO AT THIS POINT...MODELS ON THE LESS SEVERE SIDE. WILL HAVE TO MONITOR THE TRENDS TO SEE IF A TREND BACK NORTH IS IN STORE. AFTER THE SYSTEM MOVES THROUGH...NORTHWEST FLOW TAKES OVER AGAIN AND UPSLOPE OVER THE MOUNTAINS AS WELL AS ENHANCEMENT FROM LAKE MICHIGAN WILL KEEP THE CHANCE FOR SNOW SHOWERS OVER THE AREA THROUGH THE REST OF THE EXTENDED. AN INTERESTING HOLIDAY IS STORE FOR SURE. && .AVIATION.../00Z TO 24Z/...UPDATED A STRIPE OF SNOW WILL SPREAD ACROSS THE AREA OVERNIGHT... TRANSITIONING TO RAIN FROM SOUTHWEST TO NORTHEAST. A PERIOD OF SLEET AND FREEZING RAIN IS POSSIBLE AS THIS TRANSITION TAKES PLACE. SEE INDIVIDUAL TAFS FOR P-TYPE EXPECTATIONS AND TIMING. THE PRECIP WILL BECOME ALL RAIN...OR JUST DRIZZLE ON TUESDAY. CIGS WILL LOWER THROUGH THE NIGHT WITH IFR CONDITIONS LIKELY FOR MOST OF THE DAY ON TUESDAY. && .JKL WATCHES/WARNINGS/ADVISORIES...NONE. && SHORT TERM...JJ/ABE LONG TERM....SHALLENBERGER AVIATION...ABE
