ISSUED AT 1224 PM CDT WED OCT 7 2026
WE WILL CONTINUE TO SEE LIGHT NORTHERLY TO EASTERLY WINDS ALONG WITH
DRIER AIR THROUGH TOMORROW KEEPING RAIN CHANCES MINIMAL. EVEN WITH
THE DRIER AIR DEWPOINTS WILL NOT DROP MUCH TODAY AND TOMORROW
MORNING. HOWEVER, SOME AREAS ACROSS THE NORTHERN PORTION OF THE CWA
COULD SEE DEWPOINTS DROP INTO THE MID TO UPPER 50S THURSDAY NIGHT
AND INTO FRIDAY MORNING. HIGH AND LOW TEMPERATURES ARE FORECASTED TO
BE ABOVE NORMAL OR NEAR NORMAL THROUGH FRIDAY AND THE WEEKEND.
TROPICAL STORM ISAIAS HAS FORMED IN THE SOUTHWESTERN GULF. MODEL
GUIDANCE IS SLOWLY IMPROVING INTO A BETTER CONSENSUS OF BOTH TRACK
AND INTENSITY. ISAIAS IS FORECASTED TO BECOME A HURRICANE AS IT
TURNS NORTH TOWARD THE CENTRAL GULF COAST. WHILE THE TRACK HAS
WOBBLED SOME TO THE EAST AND WEST, CURRENT MODEL GUIDANCE AND NHC
FORECAST HAS BECOME MORE IN AGREEMENT OF A LANDFALL IN THE
MISSISSIPPI COAST AND THE FLORIDA PANHANDLE. GREATER IMPACTS FROM
ISAIAS ARE EXPECTED TO REMAIN EAST OF OUR CWA; HOWEVER A DEEP
SURGE OF TROPICAL MOISTURE FROM ISAIAS WILL INCREASE OUR RAIN
CHANCES FRIDAY AFTERNOON THROUGH THE WEEKEND. WE CAN ALSO EXPECT
TO SEE SOME BREEZY CONDITIONS IN BOTH SUSTAINED WIND SPEEDS
(10-15KTS) AND WIND GUSTS (15-20KTS) FRIDAY DUE TO THE PROXIMITY
OF THE STORM.
