AREA FORECAST DISCUSSION

1140 PM CST WED NOV 9 2011

.UPDATE...
AVIATION DISCUSSION.

&&

.DISCUSSION...

AFTER MAKING AN EARLIER UPDATE TO ACCOUNT FOR GREATER RAIN COVERAGE
DURING THE EARLY EVENING...ANOTHER UPDATE WILL BE MADE SHORTLY TO
ACCOUNT FOR RAIN SHIFTING EASTWARD AND DIMINISHING.  EXPECT MOST OF
THE SIGNIFICANT RAIN TO END IN OUR AREA BY MIDNIGHT...ALTHOUGH
THERE'S BOUND TO BE A FEW SPRINKLES AROUND THE SOUTHEASTERN PORTIONS
FOR A LITTLE BIT BEYOND THAT.

I HAVE DECIDED NOT TO MAKE ANY CHANGES TO THE LOW TEMPERATURE
FORECAST FOR TONIGHT. TEMPS INITIALLY COOLED A BIT QUICKER THAN
FORECAST BEHIND THE FRONT...BUT I THINK THINGS WILL EVEN OUT OVER
THE NEXT COUPLE OF HOURS. I DID MAKE THE NECESSARY ADJUSTMENTS TO
HOURLY TEMPS AND DEW POINTS...BASED ON LATEST OBS.

LOTS OF LOW LEVEL MOISTURE AROUND...BUT WINDS WILL STAY UP ENOUGH TO
KEEP FOG FROM BECOMING AN ISSUE.

/61/

.AVIATION...
06Z TAF DISCUSSION.

THE COLD FRONT HAS PUSHED THROUGH CENTRAL ALABAMA.  SOME LIGHT RAIN
LINGERS ACROSS SOUTEAST ALABAMA FROM KTOI-KAUO AND EASTWARD...BUT
THE INTENSITY IF VERY LIGHT AND NOT RESTRICTING VSBYS...SO
PRECIPITATION WAS LEFT OUT OF TAFS.  AREAS ALONG AND SOUTH OF I-85
IN ALABAMA WILL STILL SEE LCL MVFR CIGS...BUT DRIER AIR ADVECTING
SOUTHWARD SHOULD PUSH THE LOWER CIGS OUT OF CENTRAL ALABAMA BY 08Z.
NORTHWEST WINDS NEAR 10 KNOTS THRU 15Z WILL INCREASE TO NEAR 15
KNOTS WITH GUSTS TO 20 KNOTS AFTER 15Z AS HIGHER WINDS MIX DOWNWARD
DURING THE HEATING OF THE DAY.

58/ROSE

.FIRE WEATHER...

LOW HUMIDITIES ASSOCIATED WITH THE INCOMING DRY AIR MASS WILL LEAD
TO POTENTIAL FIRE WEATHER CONCERNS FRIDAY AND SATURDAY
AFTERNOONS...AND HAVE KEPT THE MENTION OF SUCH IN THE HWO.
