AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE JACKSON KY
257 AM EDT FRI MAY 24 2013

.SHORT TERM...-- Changed Discussion --(TODAY THROUGH SATURDAY)
ISSUED AT 257 AM EDT FRI MAY 24 2013

SCATTERED SHOWERS ASSOCIATED WITH A COLD FRONT WERE ONGOING OVER THE
SOUTHEAST PART OF THE FORECAST AREA EARLY THIS MORNING. THEY ARE
EXPECTED TO BE GONE BY 12Z...BUT A PRE-FIRST PERIOD MAY BE NEEDED IN
THE ZFP TO COVER THEM. OTHERWISE...A DRY PERIOD IS IN STORE.

COOL HIGH PRESSURE SLOWLY BUILDING SOUTHEAST INTO THE AREA WILL BRING
DECREASING CLOUDS TODAY...AND MAINLY CLEAR SKIES TONIGHT. DEW POINTS
ARE EXPECTED TO FALL TO THE LOWER TO MID 30S THIS AFTERNOON...WITH
DAYTIME MIXING IN THE COOL AIR MASS ONLY ALLOWING MAX TEMPS IN THE
MID 60S. WITH WINDS DYING OFF TONIGHT...TEMPS SHOULD READILY DROP.
WITH FULL VEGETATION IN PLACE...A SIGNIFICANT DEW POINT RECOVERY
SHOULD OCCUR WHERE FULL WIND DECOUPLING OCCURS IN VALLEYS. THIS WILL
SET UP A BATTLE BETWEEN FOG AND FROST TONIGHT AS TEMPS FALL AND
DEPRESS THE DEW POINTS. IT IS CLIMATOLOGICALLY VERY LATE FOR
FROST...AND DO NOT THINK IT WILL BE WIDESPREAD. FOG IS LIKELY TO WIN
OUT IN MOST LOCATIONS. HOWEVER...THINK THAT SOME PATCHY FROST WILL
OCCUR. WITH THE GROWING SEASON IN FULL SWING...WILL ISSUE AN SPS FOR
PATCHY FROST...EMPHASIZING THE NEED FOR PLANT PROTECTION IN THE
NORMALLY COLDER VALLEYS.

THE SURFACE RIDGE OF HIGH PRESSURE WILL CONTINUE TO DOMINATE OUR
WEATHER SATURDAY. HOWEVER...WARM AIR ADVECTION WILL LEAD TO PRECIP
OVER THE MIDWEST TONIGHT AND SATURDAY...WITH HIGH CLOUDS STREAMING
OFF THIS ACTIVITY AND HEADING SOUTHEAST OVER OUR AREA. THIS WILL
BRING AN INCREASE IN MID-UPPER LEVEL CLOUDS FOR SATURDAY.

.LONG TERM...(SATURDAY THROUGH THURSDAY)
ISSUED AT 241 PM EDT THU MAY 23 2013

AN UPDATED LONG TERM DISCUSSION WILL BE ISSUED SHORTLY.-- End Changed Discussion --
