..NEW AVIATION
NEAR TERM...THROUGH TONIGHT
ANOTHER SUBSTANTIALLY COLD AFTERNOON WITH TEMPERATURES WELL BELOW
NORMAL, WITH RESIDUAL SNOW SLOWLY MELTING ACROSS INTERIOR AREAS OF
SE GA THIS AFTERNOON. CONCERN TONIGHT AGAIN WOULD BE WITH ANY SNOW
MELT IN POOR DRAINAGE AREAS REFREEZING LEADING TO PATCHY OR
STRETCHES OF BLACK ICE ALONG ROADWAYS IN SE GA ALONG AND NORTH OF US-
82. AN STATEMENT WILL LIKELY BE NEEDED TO HIGHLIGHT THIS THREAT
LATER TODAY.
A LOW LEVEL IMPULSE WILL CRUISE EASTWARD ACROSS THE FLORIDA
PENINSULA THIS EVENING, ENHANCING ISENTROPIC ASCENT OVER THE ARCTIC
DOME. ASSOCIATED LIFT AND LINGERING LOW LEVEL MOISTURE WILL YIELD
LOW CHANCES (20-40%) OF LIGHT RAIN SHOWERS MAINLY ACROSS THE
SOUTHERN ZONES THIS EVENING. BEHIND THE PASSING IMPULSE, A VERY
DRY ARCTIC AIRMASS WILL PLUNGE INTO THE REGION. THIS WILL LEAD TO
CLEARING SKIES THROUGH TONIGHT AND SET THE STAGE FOR ANOTHER
BITTERLY, POTENTIALLY RECORD-SETTING, COLD NIGHT. LOW TEMPERATURES
ACROSS INLAND SE GA WILL POTENTIALLY FALL INTO THE TEENS UNDER
THE MOSTLY CLEAR SKIES WHILE INLAND NE FL AREAS AND COASTAL SE GA
PLUMMET INTO THE LOW/MID 20S. FREEZING TEMPERATURES MAY EXTEND ALL
THE WAY TO THE BEACHES OF FLAGLER COUNTY AS WELL. IN ADDITION TO
THE COLD TEMPS, THERE WILL BE LIGHT NORTHWESTERLY DRAINAGE WINDS
THAT WILL PUSH APPARENT TEMPS (WIND CHILLS) TO COLD WEATHER
ADVISORY TERRITORY. ALL THAT SAID, IT WILL BE ANOTHER COLD NIGHT
WITH HARD FREEZE AND FREEZE CONDITIONS.
THOUGH CHANCES ARE MINIMAL (<20%), IN WIND SHELTERED AREAS ALONG THE
I-10 CORRIDOR, THERE COULD BE SHALLOW GROUND FOG DEVELOPMENT. GIVEN
THE SUBFREEZING TEMPERATURES,FREEZING FOG CANNOT BE RULED OUT IF
MIST BEGINS TO DEVELOP LATE TONIGHT.
SHORT TERM...FRIDAY THROUGH SATURDAY NIGHT
MOST OF THE AREA WILL NOT BREAK OUT OF THE 40S ON FRIDAY DESPITE
CLEARING SKIES AS NORTHWESTERLY WINDS CONTINUE. FRIDAY NIGHT WILL
BE BITTERLY COLD YET AGAIN, WITH HARD FREEZES LIKELY FOR SOUTHEAST
GEORGIA AND PORTIONS OF INLAND NORTHEAST FLORIDA. LOW
TEMPERATURES WILL GENERALLY BE IN THE 20S, WITH THE IMMEDIATE
SOUTHEAST GEORGIA COAST AND AREAS ALONG AND EAST OF THE ST. JOHNS
RIVER BASIN STAYING IN THE LOWER 30S. WIND CHILLS WILL NOT BE AS
COLD AS TONIGHT, HOWEVER IT IS LIKELY THAT COLD WEATHER ADVISORIES
WILL BE NEEDED FOR PORTIONS OF NORTHEAST FLORIDA AS APPARENT
TEMPERATURES DIP INTO THE 20S AREA-WIDE. WIDESPREAD FROST
FORMATION IS EXPECTED FRIDAY NIGHT AS WELL.
SLIGHT WARM UP FORECAST FOR SATURDAY, WITH HIGHS IN THE UPPER 40S
TO 50S WITH SUNNY SKIES. LOWS YET AGAIN WILL DROP BELOW FREEZING
FOR SOUTHEAST GEORGIA AND MOST OF INLAND NORTHEAST FLORIDA, WITH
WIND CHILLS IN THE 20S FOR THE SAME AREAS.
LONG TERM...SUNDAY THROUGH NEXT THURSDAY
HIGH PRESSURE BEGINS TO DOMINATE SUNDAY, WITH MAINLY DRY
CONDITIONS EXPECTED THROUGH THE PERIOD OTHER THAN SOME ISOLATED
SHOWER POTENTIAL OVER SE GA MONDAY AS A WEAK FRONT APPROACHES.
TEMPERATURES WILL SLOWLY WARM UP EACH DAY, WITH MOST OF NE FL
FINALLY REACHING 60 DEGREES ON SUNDAY, AND BY TUESDAY SOME AREAS
IN NORTH CENTRAL FLORIDA WILL SEE 70 DEGREES. LOW TEMPERATURES
SUNDAY MORNING WILL BE IN THE 20S, WITH SUNDAY NIGHT BEING THE
FINAL NIGHT IN THE NEAR-FUTURE FOR FREEZING CONDITIONS, WITH JUST
A LIGHT FREEZE OVER PORTIONS OF INLAND SE GA. THE REST OF THE
