CURRENT-TONIGHT...MID-LEVEL DRY AIR HAS BEEN A MAJOR LIMITING FACTOR  
OF PRECIP COVERAGE TODAY, WITH A FEW PASSING SHOWERS IMPACTING ONLY  
A PORTION OF EAST CENTRAL FL THIS AFTERNOON. A BULK OF THE MOISTURE  
PASSED NEAR LAKE OKEECHOBEE, AND WILL IMPACT MARTIN COUNTY OVER THE  
NEXT COUPLE OF HOURS. ADDITIONAL SCATTERED SHOWERS WILL MOVE  
EASTWARD NEAR METRO ORLANDO SOON, BUT THIS WILL LIKELY BE THE END TO  
ANY RAIN CHANCES FOR THE REMAINDER OF THE DAY. THE APPROACHING COLD  
FRONT HAS NOW CLEARED PAST TALLAHASSEE, FORCING EROSION OF CLOUD  
COVER AS IT NEARS. THE REMAINDER OF DAYLIGHT HOURS WILL STILL BE  
CLOUDY LOCALLY, WITH GUSTY SOUTH TO SOUTHWEST WINDS SOON TO VEER  
WESTERLY. THE FRONTAL BOUNDARY IS EXPECTED TO BE ON THE DOORSTEP OF  
THE LOCAL AREA BY MIDNIGHT, QUICKLY SHIFTING WINDS NORTHWEST AND  
BRINGING MUCH DRIER AIR (PW LESS THAN 0.60") AS WELL AS COOLER  
TEMPERATURES. NORTH OF I-4, LOWS TONIGHT WILL DROP TO THE LOW TO MID  
50S, BUT WITH THE FRONT BISECTING THE LOCAL AREA, SOUTHERN LOCATIONS  
WILL STILL OBSERVE TEMPS IN THE LOW/MID 60S.  
 
TOMORROW...DOMINANT HIGH PRESSURE WILL BUILD IN ACROSS THE SOUTHEAST  
AS THE FRONT EXITS SOUTH FLORIDA CREATING A SURGE OF BREEZY  
NORTHERLY WINDS OF 15-20 MPH. EVEN WITH CLEAR SKIES RETURNING,  
TEMPERATURES WILL STRUGGLE TO REACH 70 DEGREES ACROSS MOST OF THE  
AREA, WITH ONLY THE TREASURE COAST BREAKING INTO THE LOWER 70S.  
TOMORROW NIGHT WILL BE THE FIRST CHILLY NIGHT OF THE SEASON, WITH  
TEMPERATURES DIPPING INTO THE 40S AREA WIDE, EVEN REACHING THE LOWER  
40S IN RURAL LAKE, VOLUSIA AND OSCEOLA COUNTIES. WHILE WIND CHILL  
VALUES WON'T BECOME A HAZARDOUS WEATHER THREAT, THE BREEZY  
CONDITIONS WILL MAKE THE FEELS LIKE TEMPERATURES FALL INTO THE UPPER  
30S - A CLEAR INDICATION THAT ITS TIME FOR THE FLORIDIAN WINTER  
CLOTHES TO COME OUT OF HIBERNATION.  
 
FRIDAY-TUESDAY...(PREVIOUS) AN UPPER LEVEL TROUGH IS EXPECTED TO  
MOVE EAST- SOUTHEAST OVER THE SOUTHEAST US FRIDAY INTO SATURDAY  
WITH REINFORCING COLD AIR ADVECTION RESULTING IN COOLER AIR INTO  
THE WEEKEND. WINDS WILL BE BREEZY FROM THE WEST-NORTHWEST FRIDAY  
AT 12- 18MPH WITH GUST TO 25-30MPH. WINDS ARE EXPECTED TO VEER  
NORTH- NORTHEAST INTO SUNDAY AND THEN ONSHORE FROM THE EAST INTO  
NEXT WEEK. THE DRY WEATHER WILL CONTINUE THROUGH THE FORECAST  
PERIOD. AFTERNOON HIGHS IN THE UPPER 60S TO MID 70S ARE FORECAST  
WITH SUNNY SKIES FRIDAY WITH THE MID TO UPPER 60S SATURDAY.  
 
HIGH PRESSURE IS EXPECTED TO BUILD OVER THE DEEP SOUTH SATURDAY AND  
THEN SHIFT EAST OVER THE SOUTHEAST US, IN ADDITION TO THE WESTERN  
ATLANTIC SUNDAY INTO NEXT WEEK. TEMPERATURES WILL GRADUALLY WARM AS  
WINDS VEER ONSHORE INTO NEXT WEEK WITH HIGHS IN THE LOW TO MID 70S  
SUNDAY AND THE MID 70S TO LOW 80S INTO NEXT WEEK WITH SUNNY SKIES.  
LOWS IN THE UPPER 30S TO NEAR 50 DEGREES ARE FORECAST FRIDAY MORNING  
AND THROUGH THE WEEKEND BEFORE INCREASING INTO THE MID 40S TO NEAR  
60 DEGREES INTO NEXT WEEK. MINIMUM WIND CHILL VALUES ARE EXPECTED TO  
DROP INTO THE MID 30S TO MID 40S FRIDAY AND SATURDAY MORNINGS WITH  
THE LOW 40S TO LOW 50S FORECAST SUNDAY MORNING.

ISSUED AT 222 PM EST WED NOV 20 2024  
 
TONIGHT-TOMORROW...MARINE CONDITIONS WILL QUICKLY DETERIORATE  
TONIGHT AND EARLY TOMORROW AS AN APPROACHING COLD FRONT SENDS A  
BRISK NORTHERLY WIND SURGE ACROSS THE LOCAL ATLANTIC WATERS. WINDS  
REACH 20-25 KNOTS INITIALLY NORTH OF CAPE CANAVERAL JUST AFTER  
SUNSET THIS EVENING, SPREADING SOUTHWARD TO JUPITER INLET BY  
SUNRISE. SEAS WILL BUILD 6-8 FT UP TO 9 FT IN THE FAR OFFSHORE  
WATERS NORTH OF SEBASTIAN INLET. A SMALL CRAFT ADVISORY WILL GO INTO  
EFFECT THIS EVENING FOR ALL MARINE ZONES.  
 
FRIDAY-SUNDAY...HAZARDOUS CONDITIONS WILL RETREAT TO THE OFFSHORE  
WATERS LATE THURSDAY INTO FRIDAY, WITH NW WINDS STILL AT 15-25
