DISCUSSION
(SATURDAY THROUGH NEXT FRIDAY)
ISSUED AT 1136 PM CDT FRI SEP 4 2026
SYNOPTICALLY, THE UPPER LEVEL RIDGE WILL OSCILLATE FROM EAST TO
WEST TO EAST AGAIN OVER THE NEXT 7 DAYS. HIGH TEMPERATURES ARE
FORECAST TO REMAIN IN THE 95 TO 100 DEGREE RANGE DURING THIS TIME
FRAME, WITH AFTERNOON HEAT INDICES EXCEEDING 105. RAIN CHANCES
WILL EDGE UP OVER THE WEEKEND, AS THE RIDGE INITIALLY SLIDES
WESTWARD.
OVER THE NEXT 24 TO 30 HOURS, RAIN CHANCES WILL INCREASE ACROSS
THE SOUTHEAST AFTER 9 AM AS A WEAK BOUNDARY MOVES NORTHWARD.
SHOWERS AND THUNDERSTORMS ARE EXPECTED WITH HIGH CONFIDENCE
BETWEEN 10 AM AND 3 PM SOUTH OF I-85. MOVING NORTHWARD, SCATTERED
DEVELOPMENT IS ANTICIPATED BETWEEN I-85 AND THE LIVINGSTON TO
ALEXANDER CITY LINE FROM 12 PM TO 5 PM, FOLLOWED BY ACTIVITY FROM
TUSCALOOSA TO SYLACAUGA BETWEEN 2 PM AND 7 PM, AND FINALLY FROM
JASPER TO TALLADEGA BETWEEN 3 PM AND 7 PM. SCATTERED SHOWERS AND
STORMS ARE ALSO ANTICIPATED NORTH OF I-85 THROUGHOUT THE
AFTERNOON. WHILE ISOLATED ACTIVITY MAY PRECEDE THESE WINDOWS BY
ROUGHLY AN HOUR, THE HIGHEST PROBABILITIES ARE CONCENTRATED
WITHIN THESE PERIODS. SCATTERED SHOWERS WILL PERSIST THROUGH THE
EARLY EVENING ACROSS CENTRAL SECTIONS. ON SUNDAY, THE BOUNDARY
WILL SHIFT SOUTHWARD BY THE AFTERNOON AND EVENING, BRINGING THE
POTENTIAL FOR STRONGER THUNDERSTORMS TO THE SOUTHEAST; WE WILL
CONTINUE TO MONITOR TRENDS OVER THE NEXT 36 HOURS.

(06Z TAFS)
ISSUED AT 1244 AM CDT SAT SEP 5 2026
VFR CONDITIONS ARE EXPECTED THROUGH THE TAF PERIOD AT KBHM, KEET,
AND KTCL. FARTHER SOUTH, THERE IS A POTENTIAL FOR FOG AND/OR LIFR
CEILINGS AT KAUO, AND KMGM AROUND DAYBREAK. HOWEVER, CONFIDENCE
IS QUITE LOW REGARDING THE NORTHERN EXTENT OF THESE CONDITIONS,
WHICH MAY STAY JUST SOUTH OF THOSE TWO SITES. THE POTENTIAL FOR
SCATTERED SHOWERS AND THUNDERSTORMS WARRANTS A PROB30 AT KAUO AND
KMGM AFTER 18Z.
87/GRANTHAM
FIRE WEATHER
MINIMUM RH VALUES WILL GENERALLY REMAIN ABOVE 40% THROUGH THE
WEEKEND AND INTO NEXT WEEK. LOW TO MODERATE (20 TO 60%) CHANCES
OF SHOWERS AND STORMS OVER THE WEEKEND WITH THE BEST CHANCES IN
THE SOUTHEAST ON SATURDAY. LOW (10 TO 20%) CHANCES FOR SHOWERS
AND STORMS WILL BE IN THE FORECAST DAILY NEXT WEEK. FIRE WEATHER
CONCERNS ARE CURRENTLY LOW, BUT DECREASING SOIL MOISTURE WILL
BEGIN TO RAISE THESE CONCERNS BY NEXT WEEK GIVEN A LACK OF
FORECAST RAINFALL.
