AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
323 PM CST SAT JAN 10 2009

.DISCUSSION...

BIG CHANGES ON THE WAY...AFTER THIS FRONT SCOOTS SOUTH OVERNIGHT
INTO TOMORROW MORNING WE ARE LOOKING AT A MAJOR PATTERN CHANGE AS
A LARGE SCALE TROF WILL BEGIN DIGGING ACROSS THE EASTERN CONUS.
THIS WILL BEGIN THE COOL DOWN PROCESS WITH SEVERAL CHANCES TO GET
MORE OF A COLD DOWN PROCESS LATER IN THE WEEK.

THE FIRST FRONTAL BOUNDARY OF INTEREST BRINGS THE SMALL THREAT OF
PRECIP TO AREAS NORTH OF I20 ON TUESDAY MORNING. AS OF WRITING...IT
LOOKS LIKE THERE WILL BE VERY LIMITED MOISTURE TO WORK WITH...BUT
DID DECIDE TO KEEP THE THREAT FOR RAIN OR SNOW AROUND DAYBREAK.
THINKING THAT THE BEST CHANCE TO SEE FLURRIES OR LIGHT SNOW WILL
REMAIN NORTH OF THE BHM AREA...BUT AGAIN...NO REAL CONCERNS AS FAR
AS ACCUMULATIONS OR TRAVEL. THE MAIN STORY WITH THIS FRONT WILL BE
THE FIRST BLAST OF POLAR/ARCTIC AIR THAT WILL SETTLE ACROSS THE
SOUTHEAST. EXPECT CLOSE TO THE COLDEST TEMPS OF THE WINTER SO FAR
WITH ALL LOCATIONS UNDER THE 30 DEGREE MARK.

LOOK FOR SOME MODERATION ON WEDNESDAY...ESPECIALLY IN THE EVENING
HOURS AHEAD OF YET ANOTHER FRONT ON THURSDAY. MODELS HAVE FLIPPED
AND THEN FLOPPED ON WHETHER THIS FRONT WILL PRODUCE ANY PRECIP. IF
IT DOES...IT WILL ALMOST CERTAINLY BE IN THE FORM OF SNOW. FOR
NOW...GOING TO KEEP IT DRY...BUT WILL BE PAYING CLOSE ATTENTION TO
ANY TREND CHANGES WITH REGARDS TO PRECIP. JUST AS TUESDAY...THE
STORY THURSDAY WILL BE THE TRUE ARCTIC AIRMASS THAT FOLLOWS. WE
MAY BE LOOKING AT TEMPS COLDER THAN ANY OF US HAVE SEEN IN QUITE
SOME TIME...WITH HIGHS STRUGGLING INTO THE 30S AND LOWS IN THE
TEENS. WE WILL BE ON THE LOOK OUT FOR HARD FREEZE CRITERIA FROM
NEXT FRIDAY ONWARD.

TAKE THE OPPORTUNITY THIS WEEKEND TO PREPARE FOR THESE CHANGES

.AVIATION...18Z TAF DISCUSSION.

LOW LEVEL MOISTURE REMAINS ACROSS CENTRAL ALABAMA AHEAD OF AN
APPROACHING COLD FRONT. CEILINGS EXPECTED TO REMAIN VERY CLOSE TO
THE IFR/MVFR CATEGORY BREAK (007-012) THROUGH MUCH OF THE AFTERNOON
HOURS FOR NORTHERN TAF LOCATIONS. MORE BREAKS IN THE CLOUDS WILL
ALLOW MGM/TOI TO EXPERIENCE VFR CEILINGS...WITH A TREND TOWARD MVFR
BY 00Z. SCATTERED SHOWERS EXPECTED AHEAD OF THE FRONT WITH AN
GENERAL INCREASE IN COVERAGE AFTER 21Z. ADDED MENTION OF THUNDER
GENERALLY TO WESTERN LOCATIONS FROM 21-02Z. WINDS WILL BE 180-210
AROUND 10KTS AHEAD OF THE FRONT. FRONT MOVES PAST NORTHERN TAF SITES
GENERALLY BETWEEN 02-04Z AND SOUTHERN SITES BY 06-08Z. AFTER THE
FRONT...WINDS SWING AROUND TO THE NORTHWEST AROUND 10 KTS AND
EVENTUALLY TO THE NORTH BY 18Z. VISIBILITIES WILL BE REDUCED TO MVFR
MUCH OF THE TIME THROUGH 10-14Z.
