LONG TERM
(FRIDAY MORNING THROUGH NEXT TUESDAY)
ISSUED AT 235 PM EDT WED OCT 7 2026
THE EXTENDED PERIODS BEGIN WITH PRECIP FROM TROPICAL STORM ISAIAS
MOVING NORTHWARD INTO CENTRAL GA. BY DAYBREAK FRI THE STORM IS
EXPECTED TO BE A HURRICANE AND CENTERED DUE SOUTH OF MOBILE BAY
ACROSS THE CENTRAL GULF. THERE IS STILL SOME UNCERTAINTY WITH THE
INTENSITY, TRACK, AND TIMING OF THE STORM BUT THINGS APPEAR TO BE
COMING TOGETHER FOR THIS SYSTEM TO MAKE LANDFALL NEAR THE AL/FL
BORDER BETWEEN 4Z AND 8Z SAT MORNING AS A CAT 1 HURRICANE. THE
CURRENT FORECAST TRACK SHOWS ISAIAS MOVING NORTHWARD THROUGH AL SAT
WITH ITS REMNANT MOVING UP INTO KY AND THE MID-ATLANTIC AREA THROUGH
SUNDAY. AS THIS SYSTEM MOVES ONSHORE THE MODELS HAVE BEEN VERY
CONSISTENT SHOWING THE HIGH PRESSURE RIDGE OVER THE MID-ATLANTIC
STATES SETTING UP AS A WEDGE DOWN THE EASTERN SEABOARD AND INTO NE
GA. THIS RIDGE/WEDGE WILL ACT AS A STEERING MECHANISM AND HELP TO
KEEP THE CENTER OF ISAIAS TO OUR WEST. THIS WILL PUT GA ON THE MORE
ACTIVE SIDE OF THE STORM WITH INCREASED WINDS AND RAIN EXPECTED
ACROSS THE STATE. CURRENT QPF SHOWING 1 TO 3 INCH TOTALS ACROSS THE
STATE FRI NIGHT THROUGH SUN MORNING. WINDS WILL BEGIN RAMPING UP FRI
NIGHT WITH SUSTAINED WINDS IN HE 10-15MPH RANGE BY DAYBREAK SAT.
SUSTAINED WINDS WILL CONTINUE TO INCREASE INTO THE 15-20MPH RANGE
THROUGH SAT AFTERNOON WITH GUST UP TO 40MPH. THE STRONGEST WINDS
WILL BE ACROSS NORTH AND WESTERN PORTIONS OF THE STATE AS THE
PRESSURE GRADIENT TIGHTENS BETWEEN THE RIDGE/WEDGE TO THE NE AND
ISAIAS MOVING NORTH THROUGH AL. LOOKS LIKE WIND SPEEDS PEAK SAT
AFTERNOON/EVENING THEN TRAIL OFF SAT NIGHT AS THE SYSTEM WEAKENS.
BY SUN AFTERNOON HIGH PRESSURE BEGINS BUILDING BACK INTO THE AREA AS
A DEVELOPING RIDGE OVER EAST TX BECOMES CENTERED ALONG THE MS/AL
GULF COAST. THE EXITING TROPICAL SYSTEM ALSO BEGINS TO BRING IN
SOME DRIER AIR FROM THIS RIDGE CLEARING THINGS OUT ACROSS GA
THROUGH SUN NIGHT. BY MON MORNING THIS RIDGE IS EXPECTED TO BE
CENTERED OVER CENTRAL AL AND SHOULD KEEP THINGS WARM AND DRY.
