AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
307 PM EST THU NOV 20 2014

.SHORT TERM...(THIS EVENING THROUGH FRIDAY NIGHT)
ISSUED AT 307 PM EST THU NOV 20 2014

A COLD FRONT EXITED SE OUT OF THE AREA THIS MORNING...ALLOWING
ANOTHER BRIEF SURGE OF CHILLY AIR TO MOVE IN. THE AIR BEHIND THE
FRONT IS DRY...AND WITH NO PRECIP TO LEAVE RESIDUAL MOISTURE ALONG
THE WESTERN SLOPES OF THE APPALACHIANS...CLOUDS DISSOLVED QUICKLY.
HIGH PRESSURE BUILDING IN FROM THE WEST WILL BE CENTERED OVER OUR
REGION AROUND DAWN. THIS WILL RESULT IN GOOD RADIATING CONDITIONS AND
LIGHT WINDS TONIGHT...ALLOWING TEMPS TO FALL TO THE TEENS AND LOWER
20S. THE HIGH WILL SLOWLY SHIFT TO OUR EAST BY LATE IN THE DAY
FRIDAY...BRINGING AN EVENTUAL RETURN OF WARM AIR ADVECTION.
HOWEVER...IT WILL BE TOO LATE IN THE DAY TO MAKE A BIG DIFFERENCE IN
MAX TEMPS. THE WARM AIR ADVECTION PERSISTS FRIDAY NIGHT...WITH
ISENTROPIC LIFT LEADING TO AN INCREASE IN CLOUDS...ESPECIALLY IN OUR
NW COUNTIES. THERE REMAINS A SLIGHT CHANCE FOR SOME LIGHT PRECIP
THERE TOWARD DAWN. TEMPERATURES WILL LIKELY BOTTOM OUT WELL BEFORE
DAWN AND THEN LEVEL OUT OR BEGIN TO RISE. THE BIGGEST CONCERN WOULD
BE WHETHER TEMPS MAKE IT BACK ABOVE FREEZING IN OUR FAR NW BEFORE ANY
PRECIP MIGHT OCCUR. TEMPS ALOFT LOOK TOO WARM FOR ANYTHING BUT LIQUID
TO FALL...SO HAVE INCLUDED RA AND FZRA AS POTENTIAL PRECIP TYPES
TOWARD DAWN.

.LONG TERM...(FRIDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 358 AM EST THU NOV 20 2014

AN UPDATED LONG TERM FORECAST DISCUSSION WILL BE ISSUED SHORTLY.

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z FRIDAY AFTERNOON)
ISSUED AT 120 PM EST THU NOV 20 2014

VFR IS EXPECTED THROUGH THE PERIOD. THERE IS A SMALL CHANCE OF SOME
IFR OR MVFR CEILINGS LATE TONIGHT INTO EARLY FRIDAY...MAINLY IN THE
NE PART OF THE AREA. HOWEVER...AT THIS POINT THE PROBABILITY IS LOW
ENOUGH THAT THE FORECAST IS NOT CALLING FOR CEILINGS. WINDS WILL BE A
LITTLE BRISK THIS AFTERNOON...SUSTAINED AROUND 10 KTS OVER MUCH OF
THE AREA...WITH A FEW GUSTS BETWEEN 15 AND 20 KTS. THE WINDS WILL DIE
DOWN EARLY THIS EVENING.
