DISCUSSION
ISSUED AT 210 AM EST THU DEC 25 2025
EARLY THIS MORNING... CONTINUING TO MONITOR FOR PATCHY FOG EARLY
THIS MORNING. MOST GUIDANCE SUGGESTS THE POTENTIAL FOR SEA FOG TO
DEVELOP ALONG THE NATURE COAST, SLOWLY SPREADING INLAND WHERE IT MAY
REACH WESTERN PORTIONS OF LAKE COUNTY BEFORE SUNRISE. OUTSIDE OF
ADVECTIVE SEA FOG, A DECK OF MID LEVEL CLOUDS COULD WORK TO LIMIT
ADDITIONAL FOG DEVELOPMENT ACROSS THE NORTH. FURTHER SOUTH WHERE
SKIES ARE CLEAR, THERE COULD BE A BETTER CHANCE FOR RADIATIONAL FOG,
BUT CONFIDENCE IS DECREASING AT THIS TIME.
TODAY-SUNDAY... HIGH PRESSURE KEEPS WARM AND DRY CONDITIONS IN PLACE
WITH NO MENTIONABLE PRECIP THROUGH THE WEEKEND. THE SURFACE RIDGE
AXIS IS FORECAST TO HOLD IN VICINITY OF CENTRAL FLORIDA WITH LIGHT
WINDS THROUGH THE PERIOD, AND THE PRIMARY WEATHER HAZARD REMAINS
PATCHY/AREAS OF FOG EARLY EACH MORNING. AFTERNOON HIGHS WILL BE
ABOVE NORMAL, MOSTLY IN THE UPPER 70S AND NEAR 80 DEGREES. MORNING
LOWS GENERALLY RANGE THE LOW TO MID 50S, WARMING SOME ON SUNDAY.
MONDAY-THURSDAY... THE LOCAL PATTERN BEGINS TO CHANGE NEXT WEEK AS A
COLD FRONT APPROACHES THE AREA MONDAY, PASSING CENTRAL FLORIDA LATE
MONDAY NIGHT AND INTO TUESDAY. WINDS INCREASE TO 10-15 MPH OUT OF
THE WEST MONDAY, SHIFTING NORTHWEST INTO TUESDAY. CURRENT GLOBAL
MODEL RUNS ARE RELATIVELY DRY ALONG THE FRONT, KEEPING RAIN CHANCES
20 PERCENT OR LESS. MORE NOTABLY, THE FRONT WILL BRING A PERIOD OF
COLDER TEMPERATURES. MORNING LOWS IN THE LOW TO MID 50S ON TUESDAY
FALL INTO THE LOW TO MID 40S FOR MOST LOCATIONS WEDNESDAY AND
THURSDAY. THE COLDEST AREAS ARE FORECAST NORTH AND WEST OF I-4 WHERE
TEMPERATURES ARE CURRENTLY MODELED IN THE MID TO UPPER 30S.
AFTERNOON HIGHS HOLD ABOVE AVERAGE ON MONDAY AHEAD OF THE FRONT
RANGING THE UPPER 70S AND LOW 80S. BY TUESDAY HIGH TEMPERATURES FALL
INTO THE LOW TO MID 60S NEAR AND NORTH OF ORLANDO WHILE SPREADING
THE MID 60S TO LOW 70S FURTHER SOUTH. SLIGHTLY COOLER ON WEDNESDAY,
WITH MOST LOCATIONS HOLDING IN THE 60S BEFORE BEGINNING A GRADUAL
WARMING TREND THURSDAY.
