UPDATE
ISSUED AT 938 PM EST SUN JAN 19 2025
A MUCH COLDER AIRMASS MOVES INTO EAST CENTRAL FLORIDA TONIGHT
BEHIND A STRONG COLD FRONT. TEMPERATURES OBSERVED IN THE 60S THIS
EVENING WILL QUICKLY FALL, REACHING THE 40S AND 50S BY SUNRISE. A
FEW NORMALLY COLDER SPOTS ACROSS NORTHERN LAKE AND INTERIOR
VOLUSIA COUNTIES COULD EVEN DIP INTO THE UPPER 30S. DEVELOPING
NORTH WINDS ARE FORECAST TO REMAIN ELEVATED AROUND 8-12 MPH,
BECOMING GUSTY AT TIMES. RESULTING WIND CHILLS WILL FALL INTO THE
30S AND 40S ACROSS MUCH OF THE AREA, EXTENDING AS FAR SOUTH AS
LAKE OKEECHOBEE AND THE INTERIOR TREASURE COAST. ISOLATED SHOWERS
ARE POSSIBLE NORTH OF ORLANDO TONIGHT. OTHERWISE, MOSTLY DRY.

CURRENT-TONIGHT...STORMS REGENERATED EARLY THIS AFTERNOON AND
PUSHED THROUGH ORANGE, BREVARD, AND OSCEOLA COUNTIES. A FEW STRONG
STORMS MAY STILL OCCUR THROUGH LATE AFTERNOON SOUTHWARD, BUT THE
OVERALL TREND INTO LATE TODAY IS FOR GRADUAL WEAKENING. PRIMARY
LIGHTNING STORM THREATS REMAIN OCCASIONAL CLOUD-TO-GROUND
LIGHTNING STRIKES, STRONG WINDS GUSTS OF 45 TO 55 MPH IN A STORM
OR TWO, AND TORRENTIAL DOWNPOURS. THE ISOLATED TORNADO THREAT IS
WANING INTO LATE AFTERNOON.
OUR WIND ADVISORY EXPIRES AT 3PM FOR BREVARD-OSCEOLA COUNTIES
SOUTHWARD. BREEZY/GUSTY CONDITIONS WILL CONTINUE AREAWIDE THRU
NEAR SUNSET. SW/WSW DIRECTIONAL COMPONENT WILL CONTINUE TO VEER
THIS EVENING TO W/NW AS THE STRONG COLD FRONT TO THE NORTH
NEARS/PASSES THRU THE AREA. SPEEDS WILL REMAIN ELEVATED INTO
TONIGHT 10-15 MPH WITH SOME GUSTS 20-25 MPH AS THE PRESSURE
GRADIENT REMAINS TIGHT. WHILE THERE WILL BE SOME DRIER AIR PUSHING
SOUTHWARD IN THE LOW-LEVELS BEHIND THE FRONT, THERE WILL STILL BE
SIGNIFICANT OVERRUNNING MOISTURE ACROSS ECFL, THEREFORE RETAINING
CONSIDERABLY TO MCLOUDY SKIES THRU TONIGHT.
OUR MAX TEMPS THIS AFTERNOON HAVE FOUND THEIR WAY INTO THE L-M70S
NORTHWARD WITH L-M80S FURTHER SOUTH. HOWEVER, EXPECT COLDER TEMPS
TONIGHT, POST-FRONTAL, WITH U30S TO L40S ALONG/NORTH OF I-4, THEN
40S FURTHER SOUTHWARD TOWARD LAKE OKEECHOBEE ACROSS THE INTERIOR,
WITH L50S ACROSS THE TREASURE COAST - PERHAPS A FEW M50S EASTERN
MARTIN COUNTY. LOWEST WIND CHILLS MAY APPROACH L-M30S NORTH OF I-4
TOWARD SUNRISE, AND M-U30S TO L40S MOST EVERYWHERE ELSE, EXCEPT
OKEECHOBEE AND THE TREASURE COAST WHERE THEY WILL STAY HIGHER.
MON-WED...PREVIOUS MODIFIED...THE FRONT IS FORECAST TO STALL ACROSS
THE FL STRAITS MON WITH MOSTLY DRY WEATHER ACROSS EC FL WITH THE
EXCEPTION OF ISOLATED SHOWERS (POPS ~20%) FORECAST OVER THE TREASURE
COAST. RAIN CHANCES INCREASE NORTHWARD MON OVERNIGHT-TUE AS A
COASTAL TROUGH MOVES NORTH OVER THE WESTERN ATLANTIC ALONG THE COAST
OF EAST CENTRAL FLORIDA INTO TUE AFTERNOON. SCATTERED TO NUMEROUS
SHOWERS (POPS ~50-60%) ARE FORECAST TO DEVELOP FROM SOUTH TO NORTH
OVER EAST CENTRAL FLORIDA LATE MON NIGHT AND CONTINUE MOST IF NOT
ALL DAY TUE BECOME WIDESPREAD. IT IS UNUSUAL TO GET AN ALL-DAY RAIN
HERE IN CENTRAL FL (OUTSIDE OF TROPICAL SYSTEMS) BUT CONDITIONS LOOK
FAVORABLE FOR THIS INCLUDING A STALLED FRONTAL BOUNDARY, OVERRUNNING
AND UPPER SUPPORT. THE MAIN HAZARDS TUE WILL BE GUSTY NORTHERLY
WINDS AND MODERATE TO LOCALLY HEAVY RAINFALL. MAX TEMPS MON WILL BE
MUCH BELOW NORMAL ONLY REACHING THE LOW TO MID 50S ACROSS THE NORTH
TO THE MID 60S TREASURE COAST. UPPER 50S LAKE COUNTY TO LOW 70S
TREASURE COAST FORECAST ON TUE. COLD TEMPERATURES ARE EXPECTED MON
AND TUE MORNINGS WITH LOWS GENERALLY IN THE UPPER 30S FAR NORTH TO
MID 50S TREASURE COAST AND LOWEST WIND CHILL VALUES IN THE LOW-MID
30S ALONG AND NORTH OF I 4 MON MORNING AND U30S TO L40S TUE MORNING.
THE MID-LEVEL DISTURBANCE RESPONSIBLE FOR THIS ACTIVE WEATHER IS
PREDICTED TO MOVE BY ON TUE NIGHT. THIS SHOULD FORCE THE FRONT BACK
SOUTHWARD WHILE CONTINUING THE HIGH RAIN COVERAGE. THE POTENTIAL FOR
WINDY/GUSTY CONDITIONS IS INCREASING ALONG AND JUST BEHIND THE
FRONT. STATISTICAL GUIDANCE SUPPORTS A 60-70% CHANCE OF PEAK GUSTS
EXCEEDING 35 MPH ALONG THE COAST. THIS WILL LIKELY LEAD TO HAZARDOUS
SURF CONDITIONS TUE NIGHT INTO WED.
BEHIND THE BOUNDARY, COLDER AIR IS DRAWN SOUTHWARD AGAIN, AND
SUNRISE WED TEMPERATURES ARE NOW FORECAST IN THE UPPER 30S NORTHWEST
OF ORLANDO. TEMPERATURES STILL LOOK TOO WARM FOR ANY WINTER WEATHER
IMPACTS OVER OUR FORECAST AREA. RAIN SHOWERS ARE EXPECTED TO
DIMINISH DURING THE DAY ON WED.
THU-SAT...PREVIOUS...A CONTINUED UNSETTLED WEATHER PATTERN IS
FORECAST MID TO LATE WEEK AS ANOTHER WEAK WAVE OF LOW PRESSURE RIDES
ALONG THE NEARBY STALLED FRONT. SHOWERS ARE LIKELY TO INCREASE AGAIN
ON THU (POPS 40-50%). DEPENDING ON WHERE THE SHARPENING
FRONT/BAROCLINIC ZONE SETS UP WILL DETERMINE THE HEAVIEST AXIS OF
RAIN. WINDS TURN ONSHORE WHICH WILL RESULT IN MILDER TEMPERATURES
ESP SOUTHEAST OF I-4 WITH LOW TO MID 70S TREASURE COAST FOR THU.
FINALLY, SIGNIFICANT DRYING IS FORECAST TO OVERSPREAD THE AREA FRI-
SAT BUT COLD HIGH PRESSURE WILL KEEP TEMPS BELOW NORMAL WITH MAX
TEMPS HOLDING IN THE 50S NORTH OF I 4 AND LOWS SAT MORNING IN THE
30S ACROSS ALL THE INTERIOR, INCLUDING COASTAL VOLUSIA WITH LOW TO
MID 40S ELSEWHERE.

ISSUED AT 938 PM EST SUN JAN 19 2025
TONIGHT (MODIFIED PREVIOUS)...SMALL CRAFT ADVISORIES (SCA) ARE IN
EFFECT FOR DEVELOPING NORTH WINDS BETWEEN 20-25 KNOTS BEHIND A
COLD FRONT. SEAS WILL REMAIN CHOPPY WITH 2-3 FT SEAS NEAR THE
COAST BUILDING TO 3-5 FT (PERHAPS 4-6 FT) OVERNIGHT. CONDITIONS
WILL ALSO FURTHER DETERIORATE TONIGHT OFFSHORE AS NORTH WINDS
INCREASE AND BUILD SEAS UP TO 7 FT IN THE GULF STREAM.
MON-THU...PREVIOUS...POOR TO HAZARDOUS BOATING CONDITIONS WILL
PERSIST MON DUE TO THE NORTH WINDS AND SEAS REMAINING 7 FT IN THE
GULF STREAM. A COASTAL TROUGH IS EXPECTED TO DEVELOP ON TUE AND MOVE
NORTH OVER THE WESTERN ATLANTIC ALONG THE EAST CENTRAL FLORIDA
COAST. STRONG TO NEAR GALE FORCE NORTHERLY WINDS ARE FORECAST AS LOW
PRESSURE DEVELOPS OVER THE EAST CENTRAL FLORIDA ATLANTIC WATERS INTO
WED. THE CHANCE FOR GUSTS TO GALE FORCE CONTINUES TO INCREASE. THE
BOTTOM LINE IS THAT MARINERS SHOULD MONITOR THE FORECAST AS A PERIOD
OF DANGEROUS WINDS AND SEAS ARE FORECAST FROM LATE TUE INTO WED.
DESPITE DRIER AIR MOVING INTO THE AREA LATE WEEK, WINDS AND SEAS ARE
FORECAST TO REMAIN HAZARDOUS FOR BOATING INTERESTS.
