UPDATE
ISSUED AT 1048 AM EST WED FEB 19 2025
NO CHANGES MADE TO THE CURRENT FORECAST. RAIN FROM THE LOW TO OUR
SOUTH WILL CONTINUE PUSHING THROUGH OUR REGION, WITH ONLY MINOR RAIN
CHANCES REMAINING IN THE FL BIG BEND BY 00Z. SKIES WILL REMAIN
OVERCAST, WHICH WILL MODERATE TEMPERATURES IN THE NEAR TERM. SW GA
AND SE AL CAN EXPECT TEMPERATURES TO GENERALLY HOVER WITHIN THE LOW
50S AND DEWPOINTS TO REMAIN STEADY IN THE MID TO UPPER 40S.
TEMPERATURES AND DEWPOINTS FOR THE FL PANHANDLE AND BIG BEND WILL
REMAIN IN THE MID TO LOW 50S. OUR MARINE WATERS WILL LIKELY SEE
WINDS OF 15-20 KTS AS THE LOW MOVES TOWARD THE NORTHEAST GULF, WITH
LAND AREAS FURTHER FROM THE COAST SEEING CALMER CONDITIONS.

NEAR TERM
(TODAY AND TONIGHT)
ISSUED AT 144 AM EST WED FEB 19 2025
A WEAK AREA OF LOW PRESSURE TRAVERSES THE NORTHERN GULF TODAY,
SKIRTING JUST SOUTH OF OUR OFFSHORE WATERS. NORTH OF THIS SYSTEM, A
WIDESPREAD STEADY RAIN IS EXPECTED FOR MUCH OF THE MORNING AND EARLY
AFTERNOON. INSTABILITY WILL BE NEAR ZERO, SO NO THUNDER IS EXPECTED.
THE BULK OF THE RAIN WILL EXIT EARLY THIS AFTERNOON, BUT A FEW STRAY
SHOWERS WILL REMAIN POSSIBLE THROUGH THE AFTERNOON AS THE MID-LEVEL
TROUGH SWINGS THROUGH. OTHERWISE, THE CLOUDS AND RAIN WILL KEEP
HIGHS IN THE LOWER TO MIDDLE 50S NORTH OF I-10 WITH UPPER 50S TO
LOWER 60S SOUTH.
A MUCH COLDER AIR MASS MOVES INTO THE AREA TONIGHT WITH ARCTIC HIGH
PRESSURE BUILDING OVER THE PLAINS. LOWS TONIGHT WILL RANGE FROM THE
UPPER 20S TO MID 30S ACROSS MUCH OF THE AREA ALONG AND WEST OF THE
FLINT AND APALACHICOLA RIVERS WITH UPPER 30S TO MID 40S TO THE EAST.
WITH NORTHERLY WINDS AROUND 10-15 MPH CONTINUING, WIND CHILLS COULD
DROP INTO THE UPPER TEENS TO MID 20S IN SOUTHEAST ALABAMA AND THE
FLORIDA PANHANDLE. THUS, HAVE ISSUED A COLD WEATHER ADVISORY FOR
PARTS OF THESE AREAS TONIGHT INTO THURSDAY MORNING. REMEMBER TO USE
HEATING DEVICES SAFELY AND PROTECT YOURSELF AND YOUR PETS FROM THE
COLD.
SHORT TERM
(THURSDAY THROUGH FRIDAY NIGHT)
ISSUED AT 144 AM EST WED FEB 19 2025
A COLD AND BLUSTERY START TO THURSDAY IS EXPECTED BEHIND A COLD
FRONT AS TEMPERATURES IN THE LOW 30S ACROSS SOUTHEAST ALABAMA AND
SOUTHWEST GEORGIA AND 10 TO 15 MPH WINDS CREATE WIND CHILLS IN
THE LOW TO MID 20S. DESPITE SUNNY SKIES, HIGH TEMPERATURES WILL
STRUGGLE TO CLIMB INTO THE 50S ACROSS FLORIDA AND WILL LIKELY NOT
CLIMB OUT OF THE 40S ACROSS SOUTHEAST ALABAMA AND SOUTHWEST
GEORGIA AS STEADY COLD AIR ADVECTION CONTINUES THROUGH THE DAY.
MORE OF THE SAME IS EXPECTED ON FRIDAY WITH REGARD TO TEMPERATURES
BUT WINDS SHOULD BE A FEW MPH SLOWER AS THE CENTER OF SURFACE
HIGH PRESSURE DRAWS NEAR. BY FRIDAY NIGHT, SURFACE HIGH PRESSURE
CONTINUES EAST AND LIGHT WINDS SHOULD ALLOW THE POTENTIAL FOR
PATCHY FROST OVERNIGHT INTO SATURDAY MORNING. THE MAIN UNCERTAINTY
IS INCREASING UPPER LEVEL CLOUDS AHEAD OF OUR NEXT SYSTEM WHICH
COULD KEEP TEMPERATURES WARM ENOUGH TO AVOID FROST. TO WHAT DEGREE
WILL LARGELY DEPEND HOW MUCH RADIATIONAL COOLING WE CAN ACHIEVE
OVERNIGHT AMIDST THE INCOMING UPPER LEVEL CLOUDS.
LONG TERM
(SATURDAY THROUGH TUESDAY)
ISSUED AT 144 AM EST WED FEB 19 2025
A BROAD CYCLONIC UPPER LEVEL PATTERN REMAINS IN PLACE THROUGH THE
WEEKEND AND EARLY NEXT WEEK WITH SEVERAL SYSTEMS PASSING
OVERHEAD. HOWEVER, AT THIS TIME IT APPEARS THE STORM TRACK WILL
LARGELY REMAIN SOUTH OF THE REGION, AND ANY MOISTURE RETURN IN
THIS PATTERN SEEMS INSIGNIFICANT. THIS SHOULD KEEP A RELATIVELY
DRY PATTERN IN PLACE OUTSIDE A BRIEF CHANCE FOR RAIN SHOWERS ON
SUNDAY, BUT EVEN THESE CHANCES HAVE STEADILY DECREASED OVER THE
LAST FEW MODEL CYCLES AS THE POTENTIAL UPPER LEVEL DISTURBANCE
PASSES SOUTH OF THE REGION.
NO SIGNIFICANT PUSH OF COLD AIR BEHIND THESE SYSTEMS IS
ANTICIPATED SO IT'S LIKELY WE'LL SEE A SLOW WARMING TREND INTO
EARLY NEXT WEEK.
AVIATION
(18Z TAFS)
ISSUED AT 1234 PM EST WED FEB 19 2025
THE RAIN IS PUSHING OUT OF THE REGION AND WAS LARGELY TAKEN OUT OF
THE TAFS. LOW CEILINGS ARE EXPECTED TO LINGER THROUGH THE AFTERNOON
INTO THIS EVENING BEFORE SLOWLY LIFTING LATER TONIGHT. WINDS ARE IN
THE PROCESS OF TURNING MORE NORTHERLY ACROSS ALL OF THE TAF SITES
AND EXPECTED TO PERSIST THROUGH THE ENTIRE TAF PERIOD. GUSTIER
CONDITIONS ARE FORECAST LATER TONIGHT INTO THURSDAY MORNING AS VFR
CONDITIONS RETURN TO THE REGION.
MARINE
ISSUED AT 144 AM EST WED FEB 19 2025
EASTERLY WINDS CONTINUE INCREASING TODAY AS AN AREA OF LOW
PRESSURE MOVES ACROSS THE NORTHERN GULF. WINDS TURN MORE NORTHERLY
AND REACH ADVISORY LEVEL OVER THE WESTERN WATERS LATER THIS
AFTERNOON. SEAS WILL INCREASE TO 4 TO 6 FEET BY TONIGHT. RAIN
CONTINUES TO OVERSPREAD THE REGION THIS MORNING AND INTO THE EARLY
AFTERNOON BEFORE MOVING OUT OF THE REGION THIS EVENING. A FEW
THUNDERSTORMS ARE POSSIBLE. WINDS AND SEAS REMAIN IN ADVISORY
LEVELS THROUGH AT LEAST THURSDAY AFTERNOON, BUT ELEVATED WINDS AND
SEAS SHOULD REMAIN IN PLACE UNTIL THE WEEKEND.
FIRE WEATHER
ISSUED AT 144 AM EST WED FEB 19 2025
WIDESPREAD WETTING RAINS ARE EXPECTED FOR MUCH OF THE DAY WITH POOR
TO FAIR DISPERSIONS AS A LOW PRESSURE SYSTEM MOVES ACROSS THE
NORTHERN GULF. TRANSPORT WINDS WILL BECOME NORTHERLY TO
NORTHEASTERLY TODAY AROUND 10-15 MPH, AND REMAIN THAT WAY INTO
THURSDAY. MIXING HEIGHTS INCREASE WITH A DECREASE IN CLOUDS ON
THURSDAY, LEADING TO GOOD TO EXCELLENT DISPERSIONS. NORTHEASTERLY
TRANSPORT WINDS DECREASE FRIDAY WITH GOOD DISPERSIONS AREA WIDE.
COOLER, DRIER AIR WILL LEAD TO MIN RH VALUES IN THE 20S THURSDAY AND
FRIDAY.
HYDROLOGY
ISSUED AT 144 AM EST WED FEB 19 2025
TWO SYSTEMS WILL PASS THROUGH THE REGION IN THE UPCOMING WEEK. THE
FIRST BEING TODAY, AND ANOTHER ON SUNDAY. THE FIRST SYSTEM WILL
BRING THE GREATEST RAINFALL AMOUNTS AROUND 1 TO 2 INCHES ACROSS THE
PANHANDLE, AND INTO SOUTHWEST GEORGIA. LIGHTER AMOUNTS AROUND 0.5 TO
1.0 INCH ARE EXPECTED ACROSS SOUTHEAST ALABAMA AND INTO CENTRAL
GEORGIA. LIGHTER AMOUNTS UNDER AN INCH ARE ALSO FORECAST ACROSS THE
EXTREME SOUTHEAST FLORIDA BIG BEND. VERY LIGHT AMOUNTS ARE CURRENTLY
FORECAST FOR THE SECONDARY SYSTEM ON SUNDAY AND LESS THAN 0.25
INCHES. MUCH OF THIS RAIN WILL BE BENEFICIAL AND AMOUNTS ARE NOT
GREAT ENOUGH TO BRING ANY HYDROLOGICAL CONCERNS. THE APALACHICOLA
RIVER NEAR BLOUNTSTOWN REMAINS IN MINOR FLOOD STAGE THROUGH EARLY
THURSDAY, PRIMARILY DUE TO UPSTREAM DAM RELEASES AND NOT LOCAL
RAINFALL.
