..NEW UPDATE, AVIATION
UPDATE
ISSUED AT 617 PM EST WED NOV 20 2024
INITIAL FRONTAL BOUNDARY IS OVER CENTRAL FL AT THIS HOUR WHILE THE
MAIN COLD FRONT IS UP ACROSS THE PANHANDLE. THE INITIAL FRONT
SHOULD CLEAR SOUTH FL BY AROUND 06Z WITH THE MAIN FRONT CROSSING
THURSDAY MORNING. LIGHT RAIN AND DRIZZLE HAS BEEN PATCHY THIS
EVENING AND EXPECT THAT TO CONTINUE TONIGHT UNTIL THE FRONT
ARRIVES AND BRINGS IN MUCH DRIER AIR. REMOVED ANY MENTION OF
THUNDER AS THAT THREAT HAS DIMINISHED. IT'LL BE A MOSTLY CLOUDY
EVENING WITH OVERNIGHT LOWS EVENTUALLY DROPPING INTO THE LOW TO
MID 60S AROUND THE LAKE REGION AND SW FL, WITH UPPER 60S TO AROUND
70 FOR THE EAST COAST METRO.
SHORT TERM
(REST OF TODAY THROUGH THURSDAY)
ISSUED AT 1252 PM EST WED NOV 20 2024
A COLD FRONT WILL PUSH THROUGH THE REGION TONIGHT INTO TOMORROW,
USHERING IN THE FIRST "COOL" WEATHER SNAP OF THE SEASON. SATELLITE
IMAGERY CURRENTLY POSITIONS THE FRONT OVER THE FLORIDA PANHANDLE,
WITH A BROAD AREA OF MODERATE RAIN AND SOME ISOLATED LIGHTNING
DEVELOPING AHEAD OF IT ACROSS CENTRAL FL. AS THE FRONT DROPS
THROUGH, SO WILL THE RAIN; MUCH OF SOUTH FLORIDA WILL HAVE A 40-60%
OF SCATTERED, MODERATE RAIN THAT COULD LAST THROUGH THE AFTERNOON.
ONCE THE FRONT PUSHES SOUTH OF OUR AREA, A DEEP LAYER OF NORTHERLY
WINDS WILL START TO USHER IN VERY DRY AIR, AS WELL AS THE COOLEST
TEMPERATURES OF THE SEASON THUS FAR. LOW TEMPERATURES TONIGHT WON'T
BE REFLECTIVE OF THAT AS THE REALLY COOL (COLD?) AIR WON'T BE HERE
UNTIL LATER THIS WEEK, SO TEMPS WILL ONLY DROP INTO THE LOW TO MID
60S OVER INTERIOR AND SW FL, WITH UPPER 60S OVER SE FL. THURSDAY
WILL BE DRY WITH BREEZY NORTHWEST WINDS AND GRADUALLY CLEARING
SKIES. HIGH TEMPERATURES WILL GENERALLY RANGE FROM THE LOW TO MID
70S OVER INTERIOR AND SW FL, TO THE UPPER 70S OVER SE FL.
LONG TERM
(THURSDAY NIGHT THROUGH NEXT TUESDAY)
ISSUED AT 226 PM EST WED NOV 20 2024
A STRONG COLD FRONT WILL SWEEP THROUGH THE REGION TOWARDS THE LATE
WEEK PERIOD, AS A RIDGE OF HIGH PRESSURE SITS OVER THE REGION FOR A
MAJORITY OF THE EXTENDED PERIOD. THIS WILL USHER IN A (MODIFIED)
CONTINENTIAL POLAR AIRMASS, LEADING TO THE COOLEST TEMPERATURES
OBSERVED ACROSS SOUTH FLORIDA IN QUITE SOME TIME. LOW TEMPERATURES
ARE FORECAST TO DROP INTO THE 40S AROUND LAKE OKEECHOBEE AND
INTERIOR SOUTHERN FLORIDA, WITH THE REMAINDER OF SOUTH FLORIDA IN
THE 50S FROM EARLY FRIDAY THROUGH SUNDAY. AFTERNOON HIGHS WILL TREND
5 TO 10 DEGREES BELOW THE CLIMATOLOGICAL RANGE, WITH SEVERAL
LOCATIONS NORTH OF ALLIGATOR ALLEY STRUGGLING TO REACH 70 DEGREES ON
FRIDAY AND SATURDAY.
THE HIGH PRESSURE SYSTEM WILL GRADUALLY EASTWARD, ALLOWING LOW-LEVEL
WINDS TO VEER OUT OF OUT OF THE EAST-NORTHEAST BEGINNING EARLY NEXT
WEEK. THIS WILL YIELD A WARMING TREND IN TERMS OF OBSERVED
TEMPERATURES, WITH MAXIMUM TEMPERATURES TRENDING CLOSER TO
CLIMATOLOGICAL NORMS IN THE UPPER 70S TO LOWER 80S. WITH THE
INFLUENCE OF HIGH PRESSURE RIDGING AND A DRIER AIRMASS, CONDITIONS
ARE EXPECTED TO REMAIN BENIGN AND MOSTLY DRY THROUGH THE LATER PART
OF THE WEEKEND INTO EARLY NEXT WEEK.

ISSUED AT 617 PM EST WED NOV 20 2024
LIGHT SHOWERS AHEAD OF AN APPROACHING COLD FRONT SHOULD HAVE

VEER TO THE NW LATE TONIGHT AND REMAIN NORTHERLY THROUGH THE
REMAINDER OF THE 00Z TAF PERIOD. MAINLY VFR CONDITIONS EXPECTED
ACROSS ALL OF SOUTH FL AFTER 14Z THURSDAY.
