KEY MESSAGES
UPDATED AT 1225 PM EST FRI NOV 21 2025
- DRY AND PLEASANT CONDITIONS WILL REMAIN IN PLACE ACROSS SOUTH
FLORIDA INTO THE UPCOMING WEEKEND.
- PATCHY DENSE FOG IS POSSIBLE OVERNIGHT INTO EARLY SATURDAY
MORNING MAINLY ACROSS THE LAKE OKEECHOBEE REGION AS WELL AS
INTERIOR SOUTHWEST FLORIDA.
UPDATE
ISSUED AT 1225 PM EST FRI NOV 21 2025
NO MAJOR CHANGES WERE MADE TO THE PREVIOUS FORECAST AS EVERYTHING
LOOKS ON TRACK. HIGH PRESSURE REMAINS THE DOMINATE SYNOPTIC
FEATURE ACROSS SOUTH FLORIDA HEADING INTO TONIGHT AND THEN AGAIN
ON SATURDAY KEEPING THE DRY CONDITIONS IN PLACE. CONDITIONS DO
LOOK FAVORABLE ONCE AGAIN FOR PATCHY FOG DEVELOPMENT MAINLY ACROSS
THE LAKE OKEECHOBEE REGION OVERNIGHT INTO EARLY SATURDAY MORNING.
THE LATEST HREF SHOWS A MEDIUM CHANCE (40 TO 60 PERCENT) OF SOME
OF THIS FOG BECOMING DENSE IN SPOTS ESPECIALLY WEST OF LAKE
OKEECHOBEE. THIS COULD REDUCE VISIBILITY TO A QUARTER OF A MILE OR
LESS IN SOME LOCATIONS OVERNIGHT INTO EARLY SATURDAY MORNING. ANY
FOG THAT DOES DEVELOP WILL LIFT SHORTLY AFTER SUNRISE SATURDAY.
LOW TEMPERATURES TONIGHT WILL GENERALLY RANGE FROM THE UPPER 50S
WEST OF LAKE OKEECHOBEE TO THE UPPER 60S ACROSS THE EAST COAST
METRO AREAS.
SHORT TERM
(TODAY THROUGH SATURDAY)
ISSUED AT 1214 AM EST FRI NOV 21 2025
UPPER LEVEL RIDGING CONTINUES TO PROGRESS EASTWARD TODAY WHILE AT
THE SURFACE, SOUTH FLORIDA REMAINS ON THE WESTERN EDGE OF A SURFACE
HIGH OVER THE WESTERN ATLANTIC. THIS WILL MAINTAIN EAST-
NORTHEASTERLY FLOW OVER THE AREA, AND MAINLY SUNNY CONDITIONS EACH
DAY THROUGH THE PERIOD. MOISTURE PROFILES REMAIN BELOW AVERAGE,
WITH PWAT VALUES RANGING FROM .8 INCHES TO 1 INCH, SO NO
SIGNIFICANT PRECIP IS LIKELY OUTSIDE OF MAYBE AN ISOLATED SHOWER
ALONG THE EAST COAST.
HIGH TEMPERATURES TODAY AND TOMORROW WILL REACH THE LOWER 80S
ALONG THE COASTLINE, WITH MID TO UPPER 80S POSSIBLE FOR PORTIONS OF
INTERIOR SOUTH FLORIDA.
LONG TERM
(SATURDAY NIGHT THROUGH THURSDAY)
ISSUED AT 1214 AM EST FRI NOV 21 2025
NOT MUCH CHANGE WITH THE LONG TERM OUTLOOK AS HIGH PRESSURE FIRMLY
REMAINS IN CONTROL THROUGH THE WEEKEND INTO THE NEW WORK-WEEK. LATE
IN THE WEEKEND A WEAKENING COLD FRONT WILL PROGRESS ACROSS THE
FLORIDA PENINSULA WASHOUT EARLY NEXT WEEK WITH ANOTHER AREA OF HIGH
PRESSURE BUILDING IN FROM THE NORTH. ON SUNDAY INTO MONDAY, SURFACE
FLOW MAY BRIEFLY VEER MORE NORTH-NORTHEAST BEFORE BECOMING MORE
EASTERLY ON TUESDAY. WITH A LACK OF MOISTURE, AND A LACK OF
MOISTURE ADVECTION FROM THIS FRONTAL BOUNDARY, SENSIBLE IMPACTS WILL
BE NEARLY NONEXISTENT AND WE SHOULD BE ABLE TO MAINTAIN PRIMARILY
PARTLY CLOUDY AND PLEASANT CONDITIONS EACH DAY THROUGH AT LEAST THE
LATE WEEK PERIOD NEXT WEEK. AS WE APPROACH THE END OF NEXT WEEK, THE
NEXT FRONTAL BOUNDARY WILL BE APPROACHING SOUTH FLORIDA, AND WE
COULD SEE THE RETURN OF MENTIONABLE POPS TO THE AREA. A FEW
SHOWERS COULD IMPACT LOCAL WATERS AND AROUND THE EAST COAST
THURSDAY AND FRIDAY AS THE BOUNDARY WILL REMAIN JUST TO THE NORTH.
THIS POTENTIAL WILL BE MONITORED OVER THE COMING DAYS, BUT FOR
NOW KEEPING POPS AROUND 20% FOR THE EASTERN METRO AREAS AND
ATLANTIC WATERS ON THURSDAY AND FRIDAY.
HIGH TEMPERATURES WILL REACH THE LOW TO MID 80S EACH AFTERNOON ALONG
THE COASTS WHILE SOME PORTIONS OF INLAND SW FLORIDA MAY HIT THE
UPPER 80S. OVERNIGHT LOWS WILL BE IN THE MID TO UPPER 60S.

EASTERLY WINDS RANGING BETWEEN 5 TO 10 KTS THIS AFTERNOON WILL

AGAIN OVER THE INTERIOR SECTIONS OVERNIGHT, HOWEVER, FOG
DEVELOPMENT SHOULD STAY AWAY FROM THE TERMINALS.

ISSUED AT 1214 AM EST FRI NOV 21 2025
