AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
1154 PM CST WED DEC 23 2009

.UPDATE...AVIATION DISCUSSION.

&&

.DISCUSSION...CLOUDS HAVE THINNED ACROSS THE EASTERN SECTIONS WITH
MORE ORGANIZED RAINFALL WELL TO OUR WEST.  WENT AHEAD AND CHANGED
THE TIMING OF PRECIP OVERNIGHT AND LOWERED POPS SLIGHTLY.  IN
ADDITION...WENT WITH MORE OF AN INCREASING CLOUD TREND.  OVERNIGHT
LOWS WILL BE CLOSE TO CURRENT TEMPS AND ADJUSTED THE OVERNIGHT LOW
FORECAST AND HOURLY GRIDS.

&&

.AVIATION...06Z TAF DISCUSSION.

CEILINGS SHOULD BEGIN TO DETERIORATE WITHIN THE NEXT 6 HOURS AS LOW 
CLOUDS CONTINUE TO MAKE THEIR WAY FROM THE SOUTH. THE MAIN BULK OF 
THE RAIN STILL LOOKS LIKE IT WILL BEGIN TO MOVE IN AROUND 18Z. THE 
MAIN HIGHLIGHT THOUGH FOR THIS PERIOD IS GOING TO BE THE WIND. IT'S 
GOING TO BE VERY WINDY. WINDS COULD GUST AS HIGH AS 35 KNOTS...OR 
POSSIBLY HIGHER THAN THAT. THIS IS MAINLY DUE TO THE TIGHT PRESSURE 
GRADIENT THAT WILL BE IN PLACE.

AS FOR THUNDERSTORM ACTIVITY...WE SHOULD BE ABLE TO SEE A FEW 
THUNDERSTORMS. WHETHER OR NOT WE WILL SEE A TRUE SQUALL LINE THOUGH 
IS STILL IN QUESTION. FOR NOW...LEFT VCTS TOWARDS THE END OF THE 
PERIOD. 

10/ARM

.BMX WATCHES/WARNINGS/ADVISORIES...WIND ADVISORY FOR ALL OF
CENTRAL ALABAMA FROM 6 AM THURSDAY UNTIL MIDNIGHT THURSDAY
NIGHT.
