AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
257 PM EST SAT DEC 7 2013

.SHORT TERM...(THIS EVENING THROUGH SUNDAY NIGHT)
ISSUED AT 257 PM EST SAT DEC 7 2013

PRESENTLY...A COLD FRONT IS STALLED OVER THE TENNESSEE VALLEY WITH
MUCH OF EASTERN KENTUCKY IN THE UPPER 20S TO LOWER 30S ON THE NORTH
SIDE OF THIS BOUNDARY. THERE HAS BEEN SOME EVIDENCE BASED ON OBS THAT
WE ARE SEEING A BIT OF FREEZING FOG AT HIGHER ELEVATIONS. A MID LEVEL
WAVE OVER THE SOUTHERN MISSISSIPPI RIVER VALLEY WILL PUSH NORTHEAST
TONIGHT INTO TOMORROW MORNING...BRINGING THE FRONTAL BOUNDARY BACK TO
THE NORTH AS A WARM FRONT. GOOD DYNAMICS WILL ARRIVE AFTER MIDNIGHT
OVER THE ARE WITH WIDESPREAD PRECIPITATION DEVELOPING. AS IT STANDS
NOW...WE SHOULD SEE A MIX OF PRECIPITATION AT THE ONSET AS THE
MOISTURE RUNS INTO THE COLD AIR ALREADY IN PLACE NORTH OF THE FRONT.
IT LOOKS LIKE DEPENDING ON HOW FAR NORTH/SOUTH YOU ARE WILL BE
DEPENDENT ON THE TYPE OF PRECIPITATION. AREAS IN THE SOUTH WILL
LIKELY START OFF AS EITHER SLEET OR FREEZING RAIN...WITH AREAS
FARTHER NORTH STARTING OFF AS A PERIOD OF SNOW. HOWEVER...IT LOOKS
LIKE ANY SNOW SHOULD QUICKLY CHANGE OVER TO A PERIOD OF SLEET...THEN
EVENTUALLY OVER TO FREEZING RAIN. AS TEMPERATURES WARM FROM THE
SOUTH...WE SHOULD SEE THE FREEZING RAIN THREAT SHIFT NORTHWARD AND
OUT OF EASTERN KENTUCKY DURING THE DAY SUNDAY. DEEPER MOISTURE WILL
EXIT BY SUNDAY AFTERNOON...BUT LOW LEVEL MOISTURE WILL REMAIN
SUPPORTING A PERIOD OF DRIZZLE.

ANOTHER WAVE WILL THEN PUSH ACROSS SOUTHEAST KENTUCKY SUNDAY NIGHT
INTO EARLY MONDAY...PRODUCING THE POTENTIAL FOR MORE RAIN...PERHAPS
HEAVY ACROSS FAR SOUTHEAST KENTUCKY. THIS WILL PRESENT THE AREA WITH
ANOTHER SOAKING RAIN...WHICH WILL CREATE ADDITIONAL FLOODING
CONCERNS. THUS...THE FLOOD WATCH WILL CONTINUE FROM LATE TONIGHT
THROUGH SUNDAY NIGHT. THIS TIME AROUND THE GREATEST THREAT FOR HEAVY
RAIN SHOULD RESIDE ACROSS FAR SOUTHEAST KENTUCKY. MILD WEATHER WILL
ACCOMPANY THE RAIN SUNDAY NIGHT WITH TEMPERATURES CLIMBING INTO THE
40S.

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 257 PM EST SAT DEC 7 2013

LONG TERM DISCUSSION WILL FOLLOW SHORTLY.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON)
ISSUED AT 1227 PM EST SAT DEC 7 2013

IFR/MVFR CIGS WILL REMAIN LOCKED IN ACROSS THE AREA THROUGH THE REST
OF THE DAY. ANOTHER STORM SYSTEM WILL TAKE SHAPE TONIGHT AND PUSH
NORTH INTO THE REGION. THIS WILL SEND ANOTHER SURGE OF MOISTURE
ACROSS THE AREA LATE TONIGHT THROUGH TOMORROW NIGHT. CEILINGS WILL
AGAIN REMAIN IN THE IFR CATEGORY THROUGH MUCH OF THE FORECAST PERIOD.
IN ADDITION...SNOW...FREEZING RAIN...AND SLEET WILL BE POSSIBLE
TONIGHT INTO TOMORROW MORNING BEFORE CHANGING OVER TO RAIN. THE RAIN
COULD BE HEAVY AT TIMES THROUGH MONDAY NIGHT. THIS WILL YIELD SOME
PATCHY FOG AT TIMES AS WELL.
