NATIONAL WEATHER SERVICE JACKSON KY
333 PM EDT TUE APR 22 2014

.SHORT TERM...(THIS EVENING THROUGH WEDNESDAY NIGHT)
ISSUED AT 333 PM EDT TUE APR 22 2014

CURRENT CONDITIONS AS OF 19Z FEATURE SOME ISOLATED SHOWERS HANGING
AROUND THE AREA AS THE FRONT STILL LIES JUST TO THE WEST AS IT BEGINS
TO CROSS THE I-75 CORRIDOR. THIS WILL ESSENTIALLY BRING AN END TO
THE SHOWER ACTIVITY THIS EVENING. OBS UPSTREAM HAVE DEWS IN THE LOWER
TO MID 30S MOVING INTO THE AREA ALONG WITH MUCH COOLER TEMPS. THIS
AIRMASS WILL BE MOVING IN OVER EASTERN KENTUCKY FOR TONIGHT AND WITH
CLEARING SKIES BEHIND THE FRONT...TEMPS WILL FALL INTO THE 30S
TONIGHT...ESPECIALLY IN THE BLUEGRASS AND IN THE SHELTERED VALLEYS.
THEREFORE...WILL GO WITH AN SPS MENTIONING THE FROST POTENTIAL
TONIGHT. THIS WILL MOSTLY BE THE VALLEYS AS SOME OF THE RIDGE TONIGHT
WILL KEEP SOME STRONGER WINDS...AND WILL SHOW A BIT OF A RIDGE
VALLEY SPLIT TONIGHT BUT ONLY AROUND A 5 DEGREE DIFFERENCE.

HEADING INTO TOMORROW...THE SHOWER ACTIVITY TODAY DID NOT PROVIDE
MUCH OF A SOAKING...ESPECIALLY GIVEN THE SCATTERED NATURE TODAY AND
SO THE RELATIVE HUMIDITY VALUES TONIGHT WILL NOT RECOVER MUCH ABOVE
70 PERCENT IN MOST PLACES. AS WELL...MODEL SOUNDINGS SHOW QUITE A DRY
POCKET OF AIR ALOFT TOMORROW TO MIX DOWN AND WHILE WE WILL LIKELY NOT
MIX INTO THE STRONGER WINDS ABOVE...RH WILL STILL BE DOWN INTO THE
CRITICAL VALUES TOMORROW AFTERNOON AND SO WILL MENTION FIRE WEATHER
IN THE SPS AS WELL. WITH HIGH PRESSURE REMAINING IN CONTROL THROUGH
TOMORROW NIGHT...WILL KEEP A DRY FORECAST THROUGH THE SHORT TERM AND
KEEP SKY COVER MOSTLY CLEAR. THE OF THE COOLER AIRMASS WILL REMAIN
OVER THE AREA THROUGH TOMORROW NIGHT AS LOW TEMPS WILL GET DOWN INTO
THE LOW 40S ON THE RIDGES AND INTO THE LOW 30S IN SOME OF THE DEEPER
VALLEYS. THE RIDGE SHIFTING THROUGH THE AREA WILL KEEP CLOUD COVER
MOSTLY CLEAR AND ANOTHER NIGHT OF RADIATIONAL COOLER WILL ENSUE AS
A RIDGE VALLEY SPLIT OF 10 DEGREES WILL BE IN PLACE. FROST ALSO LOOKS
TO BE ANOTHER THREAT THURSDAY MORNING.
