AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE TALLAHASSEE FL
941 AM EST FRI JAN 8 2010
...ARCTIC AIR POURING INTO THE DEEP SOUTH...
.UPDATE...THE COLD FRONT HAS PUSHED THROUGH THE ENTIRE CWA THIS
MORNING WITH BITTERLY COLD AIR POURING IN. 14Z TEMPERATURES RANGED
FROM THE MID 20S OVER SOUTHEAST ALABAMA TO THE LOWER 40S IN DIXIE
COUNTY JUST NORTH OF THE FRONT. WITH STRONG COLD AIR ADVECTION AND
HIGH CLOUDS STREAMING ACROSS THE AREA...TEMPERATURES WILL STRUGGLE
TO WARM DURING THE DAY. HAVE ADJUSTED TEMPERATURES DOWN FOR THIS
AFTERNOON WITH MOST AREAS EXPECTED TO REMAIN IN THE 30S THROUGH
THE AFTERNOON.
A BAND OF SHOWERS IS SITUATED BEHIND THE COLD FRONT EXTENDING FROM
THE EASTERN BIG BEND TO JUST OFFSHORE OF APALACHICOLA. THIS BAND
WILL CONTINUE TO PUSH SLOWLY SOUTH THROUGH THE DAY. ALTHOUGH THERE
WERE ISOLATED REPORTS OF ICE PELLETS MIXING IN WITH THE RAIN
EARLIER THIS MORNING...TEMPERATURES OVER THE EASTERN BIG BEND
THROUGH THE REST OF THE MORNING WILL SUPPORT ONLY RAIN.
&&
.AVIATION...THE COLD FRONT AND ASSOCIATED RAIN PUSHED ITS WAY
THROUGH THE REGION EARLY THIS MORNING AND IS NOW SE OF ALL
TERMINALS. BASED ON RECENT RADAR TRENDS...IT APPEARS THAT THE LIGHT
RAIN HAS MOVED EASTWARD AND SHOULD REMAIN AWAY FROM THE TERMINALS.
THERE IS A CHANCE OF A STRAY SHOWER BEHIND THE MAIN BAND OF RAIN AT
PFN...TLH...OR VLD...BUT CONFIDENCE IN THAT SCENARIO IS LOW SO RAIN
WAS NOT MENTIONED IN TAFS. VFR CONDITIONS ARE EXPECTED AS THE SKIES
BEGIN TO CLEAR FROM W TO E BEHIND THE COLD FRONT. WINDS SHOULD PICK
UP OVER THE NEXT FEW HOURS WITH GUSTY CONDITIONS PROBABLE AT MOST
TERMINALS AS THE ARCTIC AIR BEGINS TO FILTER INTO THE REGION.
&&
.MARINE...STRONG OFFSHORE FLOW WILL CONTINUE ALL DAY IN THE WAKE
OF THIS MORNINGS COLD FRONT. ADVISORY CONDITIONS EXPECTED TO
CONTINUE THROUGH THE NIGHT TONIGHT.
