.DISCUSSION...

DRY COLD FRONT HAS ENTERED NW AL AND WILL CONTINUE TO PUSH SE THRU
THE NIGHT. SEEING SOME LIGHT FREEZING FOG DEVELOPING WITHIN THE
CLOUD FREE AREAS WHERE TEMPS HAVE DROPPED A BIT QUICKER. HAVE
ADDED PATCHY FREEZING FOG FOR AREAS WITHIN ABOUT 40-50 MILES ON
EITHER SIDE OF I-20 THRU MIDNIGHT. THE PASSAGE OF THE COLD FRONT
AND EXPECTED INCREASE IN CLOUD COVER AND WINDS SHOULD HELP DISSIPATE
THE FOG. ALSO INCREASED LOWS A COUPLE DEGREES IN THE FAR NW DUE TO
MORE PROLONGED CLOUD COVER. LOW TEMPS WILL BE IN THE LOW/MID 20S
NORTHERN HALF AND UPPER 20S/LOW 30S SOUTHERN HALF. UPDATES WILL BE
OUT SHORTLY.

06Z TAF DISCUSSION.

PATCHY DENSE FOG HAS DEVELOPED OVER EAST CENTRAL ALABAMA IN AREA
OF CLEAR SKIES AND LIGHT WINDS. THE FOG IS AFFECTING KASN AND KANB
AND WITH TEMPERATURES BELOW FREEZING...FZFG HAS BEEN REPORTED AT
KASN. A COLD FRONT WILL PUSH TO NEAR THE I-20 CORRIDOR BY 08Z AND
THIS SHOULD BRING AN END TO THE DENSE FOG AS NORTHWEST WINDS
INCREASE TO 8-10 KNOTS. THE POST-FRONTAL CLOUDS HAVE BEEN SLOW TO
PROGRESS SOUTHWARD AND HAVE DELAYED THE ONSET OF CIGS ACROSS THE
NORTHERN TAF SITES. CIGS MAY INITIALLY START AT 3500 FEET BUT
SHOULD LOWER TO 1500-2000 FEET BY 1200 UTC. AN INVERSION ALOFT
SHOULD KEEP THE CIGS INTACT THRU THE MORNING...BUT EXPECT CLOUDS
TO SCATTER BY 21Z AT MOST LOCATIONS. AT THIS TIME...DO NOT EXPECT
CIGS TO MAKE IT AS FAR SOUTH AS KMGM AND KTOI.
