AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
300 PM EDT SAT OCT 25 2014

.SHORT TERM...(THIS EVENING THROUGH SUNDAY NIGHT)
ISSUED AT 300 PM EDT SAT OCT 25 2014

A WEAK COLD FRONT WILL PASS SOUTHWARD THROUGH THE REGION TONIGHT
WITH LITTLE FANFARE. HOWEVER...ITS PRESENCE DOES COMPLICATE WHAT
WOULD BE AN OTHERWISE BENIGN FORECAST AS MOISTURE POOLING IN ADVANCE
OF THE BOUNDARY WILL RESULT IN A RIBBON OF AMPLE LOW LEVEL
MOISTURE...MAINLY BELOW 900 MB ADVECTING INTO THE AREA OVERNIGHT. AS
SURFACE HIGH PRESSURE BEGINS TO BUILD IN FROM THE WEST LATE TONIGHT
AND SURFACE WINDS SUBSIDE...IT IS POSSIBLE WIDESPREAD FOG MAY
DEVELOP. THE GREATEST POTENTIAL FOR THIS WOULD BE OVER SOUTH CENTRAL
AND SOUTHEAST KENTUCKY. SHOULD ENOUGH MIXING HANG IN...THIS MAY
MANIFEST AS A LOW CLOUD DECK WITH JUST PATCHY FOG AT THE SURFACE.
SO...WILL STAY CONSERVATIVE FOR NOW AND JUST MENTION PATCHY FOG IN
THE FORECAST.

THE REST OF THE PERIOD WILL BE MOSTLY CLEAR AND DRY. TEMPERATURES
TOMORROW WILL BE SIMILAR TO TODAY AS THE FRONTAL PASSAGE TEMPORARILY
STALLS OUR WARMING TREND. OVERNIGHT LOWS TONIGHT AND SUNDAY NIGHT
WILL FALL INTO THE 45 TO 50 DEGREE RANGE FOR MOST LOCATIONS.

.LONG TERM...(MONDAY THROUGH SATURDAY)
ISSUED AT 300 PM EDT SAT OCT 25 2014

COMING SOON...

.AVIATION...(FOR THE 18Z TAFS THROUGH 18Z SUNDAY AFTERNOON)
ISSUED AT 154 PM EDT SAT OCT 25 2014

CLOUDS HAVE OVERSPREAD THE AREA AS A WEAK COLD FRONT DROPS INTO THE
REGION...WITH MVFR CIELINGS OBSERVED MAINLY ALONG AND NORTH OF I-64.
THE LOWER CIGS MAY MAKE IT AS FAR SOUTH AS JKL...THUS THE TEMPO MVFR
CONDITIONS IN THAT TAF...BUT OTHERWISE CLOUDS SHOULD STAY VFR THIS
AFTERNOON. A LITTLE CONCERNED THAT LOW CLOUDS MAY REDEVELOP TONIGHT
AS HAPPENED LAST NIGHT IN A SIMILAR POST FRONTAL ENVIRONMENT IN
CENTRAL ILLINOIS. HOWEVER...MOISTURE IS VERY SHALLOW AND LOW LEVEL
WINDS STAY NORTHWESTERLY...NOT THE NORTHEASTERLY DIRECTION WHICH
TYPICALLY BRINGS THE LOW CIGS. SO...WILL ONLY ADVERTISE SCATTERED
CLOUDS AND SOME MVFR FOG AT LOZ AND SME LATE TONIGHT FOR NOW.
TOMORROW SHOULD BRING CLEAR SKIES AND LIGHT WINDS.
