SHORT TERM
(TODAY THROUGH SATURDAY)
ISSUED AT 239 PM EDT THU SEP 17 2026
THE SYNOPTIC PATTERN ACROSS THE SOUTHEAST U.S. REMAINS DOMINATED
BY A STOUT UPPER-LEVEL RIDGE CENTERED OVER THE MID-SOUTH, WHICH IS
SLOWLY RETROGRADING WESTWARD. MEANWHILE, AN UPPER LOW IS
DEVELOPING OVER THE BAHAMAS AND IS PROGGED TO MOVE WESTWARD
TOWARDS THE FLORIDA EAST COAST AND EVENTUALLY INTO THE NORTHERN
GULF. THIS SETUP CONTINUES TO FUNNEL DRY, BREEZY NORTHEASTERLY
FLOW ACROSS THE REGION TODAY, MAINTAINING UNSEASONABLY DRY
CONDITIONS WITH PWATS ON THE ORDER OF 0.8 INCHES, IN THE 10TH
PERCENTILE FOR THIS TIME OF YEAR. THE DRY PATTERN CONTINUES FRIDAY
WITH ABUNDANT SUNSHINE AND UNSEASONABLY WARM TEMPERATURES.
MOISTURE WILL BEGIN A GRADUAL RETURN, WITH PWATS INCREASING TO
1.4-1.7 INCHES BY LATE AFTERNOON AND EVENING, THOUGH RAIN CHANCES
REMAIN NEGLIGIBLE.
ON SATURDAY, THE UPPER LOW AND ASSOCIATED SURFACE TROUGH ARE
EXPECTED TO CRUISE ACROSS THE FLORIDA PENINSULA AND INTO THE
NORTH-CENTRAL GULF. THIS WILL SHIFT MID/UPPER LEVEL WINDS TO A
MORE SOUTHEASTERLY DIRECTION, OPENING THE DOOR FOR MORE
SIGNIFICANT MOISTURE RETURN. THIS WILL LEAD TO AN INCREASE IN
SHOWER AND THUNDERSTORM COVERAGE, WITH A SLIGHT CHANCE (20-40%) OF
AFTERNOON CONVECTION, FAVORING AREAS SOUTH OF I-10 AND THE
FLORIDA BIG BEND.
LONG TERM
(SUNDAY THROUGH NEXT WEDNESDAY)
ISSUED AT 239 PM EDT THU SEP 17 2026
THE EXTENDED FORECAST PERIOD WILL BE CHARACTERIZED BY INCREASING
MOISTURE AND DAILY CHANCES FOR SHOWERS AND THUNDERSTORMS AS THE
UPPER LOW WEAKENS INTO AN OPEN WAVE AND BECOMES ABSORBED INTO THE
BROADER FLOW. A WEAK DISTURBANCE LINGERING AROUND THE FLORIDA
PENINSULA IS FORECAST TO CONTRIBUTE TO DAILY LOCALLY HEAVY
RAINFALL POTENTIAL ACROSS THE REGION. HIGH TEMPERATURES WILL
GENERALLY BE IN THE UPPER 80S TO LOWER 90S, WITH OVERNIGHT LOWS IN
THE LOW TO MID 70S.
AVIATION
ISSUED AT 122 PM EDT THU SEP 17 2026

ISSUED AT 239 PM EDT THU SEP 17 2026
WINDS START TO RELAX FRIDAY AND INTO THE WEEKEND WITH GOOD
DISPERSIONS EXPECTED. THE DRY AIR CONTINUES FOR THE NEXT COUPLE
OF DAYS AND THUS NO RAINFALL IS EXPECTED. MOISTURE INCREASES AND
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS MAKE A RETURN
BEGINNING THIS WEEKEND. AFTERNOON HUMIDITIES THROUGH FRIDAY WILL
FALL TO THE MID 30S TO MID 40% RANGE THEN INCREASE FOR THE
