..NEW AVIATION
SHORT TERM
(TODAY THROUGH SATURDAY)
ISSUED AT 132 AM EDT FRI AUG 15 2025
MID-LEVEL RIDGING WILL START TO GRADUALLY WEAKEN AND DRIFT
NORTHWESTWARD TODAY, BUT ITS INFLUENCE WILL REMAIN FELT ACROSS THE
FLORIDA PENINSULA THROUGH THE SHORT TERM. MEANWHILE, THE SURFACE
HIGH WILL BEGIN TO SLIDE NORTHWARD AND ERODE, WITH SURFACE WINDS
SHIFTING SLIGHTLY FROM THE EAST AS A RESULT. MODEL GUIDANCE IS IN
PRETTY GOOD AGREEMENT REGARDING A SLIGHTLY DRIER AIRMASS BECOMING
ESTABLISHED ACROSS SOUTH FLORIDA TODAY, HELPING LIMIT CHANCES FOR
RAINFALL AND KEEPING HEAT INDICES BELOW ADVISORY CRITERIA FOR
ANOTHER AFTERNOON. NEVERTHELESS, CONDITIONS THIS AFTERNOON WILL
REMAIN WARM, WITH HIGHS IN THE LOW-MID 90S ACROSS THE ENTIRE CWA.
A SUBTLE TROPICAL WAVE WILL MOVE ACROSS THE FLORIDA STRAITS ON
SATURDAY, SKIRTING THE WEAKENING RIDGE, AND COULD INJECT SOME
MOISTURE BACK OVER THE AREA WHILE ALSO PROVIDING SUPPORT FOR MORE
SCATTERED TO NUMEROUS SHOWERS AND STORMS ACROSS SOUTHWEST
FLORIDA.
LONG TERM
(SATURDAY NIGHT THROUGH THURSDAY)
ISSUED AT 132 AM EDT FRI AUG 15 2025
THE SYNOPTIC PATTERN WILL CONTINUE TO GRADUALLY TRANSITION AS WE
HEAD INTO NEXT WEEK, WITH THE MID-LEVEL RIDGE CONTINUE TO SLIDE
NORTHWESTWARD - AND FINDING ITSELF OVER THE MISSISSIPPI VALLEY -
WHILE TROPICAL STORM ERIN CONTINUES TO TRAVERSE THE ATLANTIC WATERS.
THE MAIN IMPACT OF THESE SYNOPTIC CHANGES WILL BE FELT IN THE
SURFACE WIND FLOW ACROSS SOUTH FLORIDA, WITH EASTERLY WINDS
PREVAILING THROUGH THE FIRST HALF OF THE WEEK, THEN SHIFTING FROM
THE NORTH/NORTHEAST NEAR THE MIDDLE OF THE WEEK IN RESPONSE TO
ERIN'S CURVING TRAJECTORY.
HOWEVER, SENSIBLE WEATHER WILL REMAIN UNDER THE INFLUENCE OF
LOCAL PROCESSES AND SEA BREEZE DYNAMICS, WITH 60-70% POPS ACROSS
SOUTHWEST FLORIDA EACH AFTERNOON AND WARM, SUMMERTIME
TEMPERATURES PEAKING IN THE LOW TO MID 90S.
