NEAR TERM
(REST OF TODAY)
ISSUED AT 1204 PM CDT FRI OCT 9 2026
NOT MUCH IN THE WAY OF RAIN IS EXPECTED TODAY; HOWEVER, A
TIGHTENING PRESSURE GRADIENT WILL RESULT IN INCREASING WINDS
(20-30 MPH GUSTS) THIS AFTERNOON AND ESPECIALLY BY THIS EVENING.
THEN, OUR FOCUS IS ON ISAIAS AS IT APPROACHES AND MOVES OVER
NORTHERN ALABAMA THIS WEEKEND. BOTTOM LINE UP FRONT - IT'S GOING
TO BE A WINDY AND RAINY WEEKEND FOR THE TENNESSEE VALLEY, SO MAKE
SURE YOU'RE WEATHER AWARE AND PREPARED!
SHORT TERM
(TONIGHT THROUGH SUNDAY)
ISSUED AT 1204 PM CDT FRI OCT 9 2026
GUSTY WINDS WILL BE A BIG CONCERN FOR OUR AREA AS THE PRESSURE
GRADIENT TIGHTENS AS WHAT IS LEFT OF ISAIAS MOVES OVER NW AL AND
INTO TN SATURDAY THROUGH SATURDAY NIGHT. WHILE THE MAJORITY OF THE
HIGHER WINDS ARE EXPECTED ON SATURDAY/SATURDAY NIGHT, THE ONSET
OF INCREASING WINDS IS NOW ANTICIPATED LATE TONIGHT DUE TO THE
FASTER TRAJECTORY OF THE SYSTEM. WE RECENTLY UPGRADED OUR HIGH
WIND WATCH TO A HIGH WIND WARNING FOR CULLMAN, MORGAN, MARSHALL,
MADISON, JACKSON, AND DEKALB COUNTIES IN AL WITH A WIND ADVISORY
FOR OUR REMAINING COUNTIES WEST OF THESE AREAS. EXPECT WIND GUSTS
UP TO 50 MPH IN THE ADVISORY AREA AND WIND GUSTS UP TO 60 MPH
(WITH ISOLATED HIGHER GUSTS) IN THE HIGH WIND WARNING AREA. THESE
PRODUCTS ALSO NOW BEGIN SOONER (1 AM SATURDAY) DUE TO THE FASTER
PROGRESSION OF THE SYSTEM AND WILL CONTINUE THROUGH 7 AM SUNDAY
MORNING. MAKE SURE TO SECURE LOOSE ITEMS (SUCH AS HOLIDAY
DECORATIONS) AND TAKE CAUTION IF TRAVELING TOMORROW (ESPECIALLY
FOR HIGH-PROFILE VEHICLES)!
AS FOR RAINFALL, HI-RES GUIDANCE IS SUGGESTING THAT MANY OF THE
HEAVIER BANDS AND CONVECTION FROM ISAIAS WILL SET UP TO OUR EAST
(OVER GEORGIA), WITH PERHAPS NOT AS MUCH RAINFALL FOR NORTH-
CENTRAL AND NORTHEAST ALABAMA. THIS WILL DEFINITELY BE SOMETHING
WE WILL BE WATCHING, ESPECIALLY WITH THIS CONTINUOUSLY EVOLVING
SYSTEM. HOWEVER, AT THIS POINT, WE ARE MAINTAINING OUR FORECAST
AND URGE FOLKS TO BE PREPARED FOR 2-4 INCHES OF RAIN FROM TONIGHT
THROUGH SUNDAY, WITH THE POTENTIAL FOR ISOLATED AMOUNTS OF 4-6
INCHES (OR MORE). THE FLOOD WATCH THEREFORE REMAINS IN EFFECT FROM
1AM TONIGHT THROUGH 7 AM SUNDAY MORNING. THIS HEAVY RAIN MAY LEAD
TO THE FLOODING OF LOW-LYING AREAS, RIVERS, CREEKS, AND STREAMS,
AS WELL AS ROADWAYS. TURN AROUND, DON'T DOWN IF YOU ENCOUNTER
FLOODED ROADS!
OVERALL, WE URGE THE TENNESSEE VALLEY TO STAY UP TO DATE WITH THE
WEATHER THIS WEEKEND AND HAVE MULTIPLE WAYS OF RECEIVING WARNING
INFORMATION! STAY SAFE!
LONG TERM
(SUNDAY NIGHT THROUGH THURSDAY)
