.DISCUSSION...
/ISSUED 930 AM CST SAT FEB 13 2016/
850 MB ANALYSIS AT 12Z SHOWS A COLD FRONT STRETCHING FROM CENTRAL SC
THRU CENTRAL AL AND AR. STRONG COLD ADVECTION WAS UNDERWAY IN LOW
LEVELS WITH +2C AT BMX AND -12C AT OHX FOR EXAMPLE. SFC TEMPS ARE
HOLDING INTO THE M20S-A30 AT THIS HOUR, BUT EXPECT THEM TO ONLY
SLOWLY RISE OR LEVEL OFF. MIXING AND A DECENT SFC PRESSURE GRADIENT
WILL RESULT IN CONTINUED GUSTINESS AT TIMES AS WELL. SATELLITE SHOWS
A CLEAR SKY OVER MOST AREAS, BUT AS/AC DECK WAS RAPIDLY DROPPING SE
THRU WRN TN INTO FAR NWRN AL. OUR CURRENT FORECAST HAS THIS IN PLAY,
BUT HAVE OPTED TO INCREASE AFTERNOON SKY COVERAGE AS THIS OVERSPREADS
THE AREA. THE CLOUDS WILL MOST CERTAINLY PUT A LID ON TEMPS THIS
AFTERNOON, SO THE GOING COLD FORECAST LOOKS VERY GOOD AT THIS POINT.

.AVIATION...
FOR 18Z TAFS...SFC WINDS OUT OF THE NNE HAVE BEGUN TO WEAKEN A BIT
THIS LATE MORNING...WITH SPEEDS NOW CLOSER TO 8-10KT. SOME MID/HIGH
CLOUDS OUT OF THE NW ARE ALSO SPREADING INTO THE AREA...BUT CLOUD
HEIGHTS SHOULD REMAIN WELL ABOVE VFR LEVELS FOR THE MAJORITY OF THE
TAF PERIOD.
