.UPDATE...FOR 18Z TAFS

&&

.AVIATION...
VFR CONDITIONS ARE EXPECTED TO PREVAIL ACROSS CENTRAL AND
SOUTHEAST ALABAMA. AN APPROACHING COLD FRONT IS EXPECTED TO BRING

DIRECTIONS SHOULD CHANGE TO BTWN 350-030 WITH AN INCREASE TO
05-07KTS.

.PREV DISCUSSION...

QUIET WEATHER CONDITIONS ARE PREVAILING ACROSS CENTRAL ALABAMA AS
SURFACE HIGH PRESSURE REMAINS PRIOR TO A SFC COLD FRONT. CURRENT
VIS SATELLITE IMAGERY INDICATES BRIEF WISPS OF CIRRUS MAINLY
ACROSS THE I-20 CORRIDOR, BUT OTHERWISE CLEAR CONDITIONS ARE
PREVAILING. MEANWHILE, A SFC COLD FRONT CURRENTLY FROM THE
IL/KY/BOOTHILL MO TO THE OHIO RIVER VALLEY, WILL SWIFTLY MOVE
SOUTHEAST OVER THE NEXT 6 HOURS. THE MAIN IMPACT WILL BE A WIND
DIRECTION CHANGE AND A SLIGHT INCREASE IN SKY COVER MAINLY OVER
WESTERN AND SOUTHERN ALABAMA.

SO, FOR THIS FORECAST UPDATE, ADJUSTMENTS WERE MADE MAINLY FOR THE
CURRENT TRENDS AND DRYING THAT WILL BE REALIZED LATER THIS AFTERNOON
WITH THE ARCTIC FRONTAL PASSAGE. TEMPERATURES OVER SOUTHEAST
ALABAMA WERE TRENDED DOWNWARD A COUPLE OF DEGREES DUE TO THE
SLOWER WARMING THIS MORNING. IN ADDITION, THE DEWPOINT
TEMPERATURES WERE SLIGHTLY INCREASED BTWN NOW AND 18Z OVER CENTRAL
ALABAMA.

OTHERWISE, THE REST OF THE FORECAST PACKAGE LOOKS FINE.
