AREA FORECAST DISCUSSION

900 PM EST TUE DEC 16 2014

.UPDATE...
A NORTHEAST TO SOUTHWEST ORIENTED COLD FRONT CONTINUES TO PRESS
SOUTHEAST THROUGH OUR AREA...RECENTLY PASSING THROUGH BRUNSWICK
AND VALDOSTA. BUT FOR A VERY NARROW BAND OF STRATOCU
CLOUDS...VERY LITTLE MARKS THE FRONT. IN FACT MOST OF THE AREA HAS
CLEAR SKIES. A FEW LOCATIONS COULD POSSIBLY SEE A LIGHT SPRINKLE
WITH THE FRONTAL PASSAGE BUT NO MEASURABLE RAINFALL IS EXPECTED.
THE FRONT WILL REACH JACKSONVILLE BY MIDNIGHT AND THEN PUSH
THROUGH THE REST OF OUR FLORIDA COUNTIES AFTER MIDNIGHT. DRIER AND
COLDER AIR WILL ADVECT INTO THE REGION BEHIND THE FRONT. LATE
NIGHT LOWS WILL RANGE FROM AROUND 40 ACROSS SOUTHEAST GEORGIA TO
THE MID TO UPPER 40S ALONG AND SOUTH OF A LINE FROM JACKSONVILLE
TO GAINESVILLE.

HIGH PRESSURE WILL BUILD INTO THE AREA FROM THE NORTHWEST ON
WEDNESDAY. TEMPS WILL RETURN TO NORMAL LEVELS WITH MAX TEMPS IN
THE 60S UNDER SUNNY SKIES WITH LIGHT NORTHWEST WINDS.
