COLD FRONT IS CROSSING SOUTH FL EARLY THIS MORNING. ALONG AND AHEAD
OF THE FRONT, SOME LOWER CLOUDS AND PATCHY FOG IS POSSIBLE OVER SE
FL EARLY THIS MORNING. AS THE FRONTAL BOUNDARY CROSSES THE AREA
LATER THIS MORNING, MUCH DRIER AIR WILL START TO FILTER INTO THE
REGION AS HIGH PRESSURE OVER THE SOUTHERN US BUILDS IN. PLENTY OF
SUNSHINE THIS AFTERNOON WITH HIGH TEMPS ONLY MANAGING TO REACH THE
MIDDLE 60S AROUND THE LAKE TO LOW/MID 70S OVER THE FAR SOUTHERN

THE YEAR IS GOING TO END ON A COLD NOTE, WITH TEMPERATURES TUMBLING
TONIGHT INTO NEW YEARS EVE MORNING. OVERNIGHT TEMPS WEST OF THE LAKE
WILL FALL INTO THE LOW TO MIDDLE 30S AND AROUND 40 SOUTHEAST OF THE
LAKE. LOOKING AT THE LATEST HREF PROBS, GLADES, HENDRY, INLAND
COLLIER AND INLAND PALM BEACH ALL HAVE PROBS OF AT LEAST 70% FOR
REACHING APPARENT TEMPS BELOW 35 DEGREES. BASED ON THAT AND AFTER
DISCUSSION WITH NEIGHBORING OFFICES, A COLD WEATHER ADVISORY WAS
ISSUED FOR LATE TONIGHT STARTING AT 1 AM AND LASTING UNTIL 9 AM
WEDNESDAY MORNING. WAS TEMPTED TO GO WITH A FREEZE WATCH FOR GLADES
COUNTY HOWEVER THE LATEST HREF PROBS FELL TO 20-30% OVER WESTERN
GLADES, SO WILL LET THE DAY SHIFT EVALUATE LATER TODAY. OVER THE
EAST COAST METRO, LOW TEMPS WILL FALL INTO THE MID AND UPPER 40S,
WITH SOME LOWER 40S POSSIBLE ACROSS THE WESTERN SUBURBS.
WITH THE NW FLOW CONTINUING, NEW YEARS EVE WILL REMAIN CHILLY ACROSS
SOUTH FL. DESPITE MOSTLY CLEAR SKIES, HIGH TEMPS WILL STRUGGLE TO
REACH THE LOWER 60S AROUND THE LAKE AND MID AND UPPER 60S ACROSS THE
REST OF SOUTH FL. TEMPERATURES WILL QUICKLY FALL AFTER SUNSET WITH
SOME PLACES ALONG EAST COAST METRO BARELY CLINGING TO THE LOW 50S
AROUND MIDNIGHT, WHILE INLAND LOCATIONS WILL ALREADY BE INTO THE 40S
AS WE START 2026.
LONG TERM
(WEDNESDAY NIGHT THROUGH MONDAY)
ISSUED AT 1252 AM EST TUE DEC 30 2025
THERE WILL BE ONE MORE MORNING OF POTENTIAL COLD WEATHER ADVISORY
CONDITIONS ACROSS SW FL NEW YEARS DAY MORNING, BUT THEN WE SLOWLY
START A MODERATING TREND FOR THE END OF THE WEEK AND INTO THE
UPCOMING WEEKEND AS HIGH PRESSURE OVER THE GULF SHIFTS TO THE EAST.
ANOTHER FRONTAL BOUNDARY WILL CROSS THE AREA LATE IN THE WEEKEND OR
EARLY MONDAY, BUT THIS FRONT ALSO APPEARS TO BE A MAINLY DRY FRONT.
THE AIR MASS BEHIND THAT FRONT WILL HAVE NOWHERE NEAR THE COLD AIR
PUSH THAT THE CURRENT FRONT POSSESSES. LITTLE TO NO APPRECIABLE
RAINFALL IS EXPECTED DURING THE LONG TERM PERIOD.
TEMPERATURES WILL REMAIN BELOW NORMAL THROUGH THE END OF THE WEEK
