AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
439 AM CDT THU NOV 4 2010

.DISCUSSION...

PER LATEST WATER VAPOR...UPPER LOW IS PUSHING ACROSS THE NORTHERN
GULF OF MEXICO AS THE DRY AIR PUNCH ASSOCIATED WITH THE ARCTIC
TROUGH ACROSS THE CONUS PUSHES SOUTHWARD AND IS ENTERING FAR
NORTHWEST ALABAMA. LIGHT RAIN CONTINUES ACROSS PORTIONS OF THE
AREA...AHEAD OF AN ADVANCING COLD FRONT. BACK EDGE OF THE LIGHT RAIN
IS NOW ENTERING NORTHWEST CENTRAL ALABAMA. LOOKING FURTHER TO THE
NORTHWEST...DEWPOINTS IN NORTHWEST TN AND SOUTHERN MO ARE IN THE LOW
30S AND UPPER 20S.

THE COLD FRONT WILL PUSH THROUGH THE AREA THIS MORNING...ENDING THE
LIGHT RAIN AND ALLOWING SKIES TO CLEAR. EXPECT ALL RAIN TO BE EAST
OF THE AREA BY 1PM. BEHIND THE FRONT...WINDS WILL BE GUSTY FROM THE
NORTHWEST TODAY...WARRANTING A WIND ADVISORY THROUGH 7 PM TONIGHT.
WILL SEE A WARMUP TODAY AS THE CAA LAGS BEHIND THE ACTUALLY COLD
FRONT. AROUND 60 CAN BE EXPECTED IN THE NORTH BEFORE TEMPS BEGIN TO
FALL THROUGH THE AFTN HOURS. MID 60S ARE EXPECTED IN THE SOUTH.
OVERNIGHT LOWS TONIGHT WILL BE IN THE MID 30S.

CLOUDS WILL LINGER ACROSS THE AREA...ESPECIALLY IN THE NORTH...THROUGH
TOMORROW AS THE UPPER TROUGH AXIS SWINGS THROUGH THE SOUTHEAST. NOT
CONVINCED THERE WILL BE ENOUGH MOISTURE TO SQUEEZE OUT ANY LIGHT
RAIN...BUT WITH STEEPENING LAPSE RATES/COLD TEMPS ALOFT ASSOCIATED
WITH THE UPPER LOW...COULD SEE A FEW LIGHT SHOWERS IN THE NORTHEAST.
NO ACCUMULATION IS EXPECTED. AS THE UPPER LOW PULLS TO THE EAST AND
HIGH PRESSURE CONTINUES TO BUILD INTO THE AREA...WINDS WILL BE
BREEZY AGAIN. FOR NOW GUSTS ARE FORECASTED TO REMAIN JUST BELOW WIND
ADVISORY CRITERIA. HIGHS FRIDAY WILL BE IN THE LOW TO MID 50S.

AS THE SURFACE HIGH SETTLES ACROSS THE SOUTHEAST FOR THE
WEEKEND...CLEAR SKIES AND LIGHT WINDS WILL ALLOW FOR THE COLDEST
TEMPERATURES OF THE SEASON...WITH LOWS IN THE LOW 30S AND UPPER 20S
AREAWIDE. A FREEZE WATCH WILL BE ISSUED FOR THE ENTIRE AREA FOR
SATURDAY MORNING. HIGHS SATURDAY WILL BE IN THE MID 50S...WITH A
RELAXED WIND FIELD AND CLEAR SKIES. DESPITE LOWS SUNDAY MORNING BEING A
DEGREE OR TWO HIGHER THAN THE PREVIOUS NIGHT...A FREEZE WATCH WILL
LIKELY BE NEEDED FOR THAT PERIOD AS WELL.

THE AIRMASS WILL MODERATE THROUGH THE FIRST HALF OF THE WORK WEEK AS
THE SURFACE HIGH SHIFTS EASTWARD AND SOUTHERLY FLOW RETURNS TO THE
AREA. DRY CONDITIONS ARE EXPECTED THROUGH MID WEEK WITH HIGHS BACK
INTO 60S AND LOWS IN THE 40S.

.AVIATION...06Z TAF DISCUSSION.

-RA AND -SHRA CONTINUES FOR MANY TAF SITES.  THE MAIN AVIATION
CONCERN THROUGH THE NEXT 6 HOURS WILL BE THE LOW CIGS AND LOW
VIS...MAINLY IN THE MVFR AND POTENTIALLY IFR CATEGORY.  WILL NEED TO
CLOSELY MONITOR THE VIS THROUGH THE REMAINDER OF THE OVERNIGHT FOR
POSSIBLY VENTURING TOWARDS THE LOW END AS SOME ISOLATED NON TAF
SPOTS ARE BEGINNING TO REPORT 1 MILE OR LESS.  THIS WILL MAINLY
PERSIST IN THE PREFRONTAL ENVIRONMENT.  THE COLD FRONT IS
APPROACHING FROM THE NORTHWEST...NOW ACROSS WESTERN MS AND TN. ITS
PASSAGE WILL BE BRING STRONGER WINDS AND IMPROVING VIS AND CIGS.
FOR MOST SITES THIS WILL OCCUR TOWARDS DAYBREAK.

NOTICE...KEET TAF WILL HAVE (AMD LTD TO VIS WIND AND WX) AMENDED TO
THE END OF THE FORECAST THROUGH THE END OF 2010. THE CEILOMETER DATA
WILL BE GOING THROUGH NUMEROUS TESTS AND MONITORED FOR ACCURACY.
