ISSUED AT 200 PM EDT TUE OCT 14 2025
GENERALLY HIGH PRESSURE DOMINATES THE REGION WITH PLEASANT TEMPS
MOSTLY IN THE 80S, EXCEPT FOR MID TO UPPER 70S ALONG THE COAST
FROM ONSHORE. A WEAK TROUGH OF LOW PRES/RE-ENFORCING BACKDOOR
FRONT EXPECTED TO MOVE INTO THE REGION LATER TONIGHT. THIS WILL
BRING IN SOME LOW LEVEL MOISTURE AND A BIT COOLER AIRMASS GOING
INTO WED. WITH THE WINDS INCREASING A BIT TONIGHT, DON'T EXPECT AS
MUCH PATCHY TO AREAS OF FOG AS THIS MORNING SO FOR NOW IS NOT
INCLUDED IN THE TONIGHT FORECAST. LOWS TONIGHT AGAIN ON THE COOL
SIDE WITH SOME UPPER 50S INLAND AND UPPER 60S COAST UNDER MOSTLY
CLEAR SKIES.
SHORT TERM AND LONG TERM
ISSUED AT 200 PM EDT TUE OCT 14 2025
(WEDNESDAY THROUGH MONDAY)
DRY AND WARM CONDITIONS PERSIST THROUGH THE WEEK UNDER MID/UPPER
RIDGING BUILDING OVER THE REGION. BREEZY NNE WINDS ON WEDNESDAY
MAY BRING A FEW SPRINKLES ONSHORE TO FLAGLER COUNTY. LARGE SURFACE
HIGH PRESSURE OVER THE GREAT LAKES SHIFTS SOUTHEASTWARD AND
WEDGES DOWN THE EASTERN SEABOARD INTO FRIDAY PUSHING ANOTHER
REINFORCING DRY FRONT THROUGH THE AREA. THIS SETUP WILL MAINTAIN
THE DRY AIRMASS (PWATS ~1 INCH) OVER THE REGION AND BREEZY NE
WINDS. SURFACE HIGH PRESSURE THEN SHIFTS OFF THE SOUTHEAST US
COAST THIS WEEKEND SHIFTING THE LOCAL FLOW TO MORE SOUTHERLY
RESULTING IN SOME MOISTURE RETURN TO THE AREA. AN UPPER TROUGH
DEEPENS ACROSS THE CENTRAL US AS A COLD FRONT MOVES ACROSS THE SE
US THIS WEEKEND. THE FRONT WILL MOVE ACROSS THE AREA LATE SUNDAY
INTO MONDAY BRINGING OUR NEXT CHANCE FOR RAIN. MODELS CONTINUE TO
DISAGREE ON THE EVOLUTION OF THE UPPER TROUGH AND MOISTURE RETURN
AHEAD OF THE FRONT. AT THIS TIME, HAVE ISOLATED TO WIDELY
SCATTERED SHOWERS WITH A FEW EMBEDDED THUNDERSTORMS SUNDAY INTO
