DISCUSSION
(WEDNESDAY THROUGH NEXT TUESDAY)
ISSUED AT 1137 PM CDT TUE SEP 22 2026
AS A COLD FRONT SLOWLY MOVES THROUGH THE REGION INTO WEDNESDAY,
SHOWER AND THUNDERSTORM ACTIVITY WILL GRADUALLY TAPER OFF FROM
NORTHWEST TO SOUTHEAST. A FEW STRONGER STORMS REMAIN POSSIBLE
ACROSS THE NORTHEAST THROUGH WEDNESDAY AFTERNOON AS THE FRONT
PROGRESSES. A DEEPENING TROUGH WILL DEVELOP TO OUR EAST WEDNESDAY
THROUGH THE WEEKEND WHILE A RIDGE BUILDS TO OUR WEST. UNTIL THE
RIDGE BECOMES FIRMLY ESTABLISHED, ISOLATED SHOWERS MAY PERSIST
ALONG THE FRONT IN WESTERN AREAS THROUGH EARLY THURSDAY
AFTERNOON.
FOLLOWING SEVERAL WEEKS OF ABOVE-NORMAL TEMPERATURES, A WELCOME
TRANSITION TO FALL-LIKE CONDITIONS IS EXPECTED. DAYTIME HIGHS
WILL RANGE FROM THE LOW TO MID-80S ACROSS MUCH OF THE AREA, WITH
UPPER 70S LIMITED TO FAR EASTERN PORTIONS OF CENTRAL ALABAMA.
OVERNIGHT LOWS WILL DROP INTO THE MID-TO-UPPER 50S ACROSS
NORTHERN SECTIONS, WITH LOWER-TO-MIDDLE 60S FURTHER SOUTH. THIS
DRY, SEASONABLE REGIME WILL PERSIST THROUGH THE UPCOMING WEEKEND
AND INTO EARLY NEXT WEEK, BRINGING TRANQUIL CONDITIONS AND LITTLE
TO NO RAIN POTENTIAL ACROSS ALL OF CENTRAL ALABAMA.

(12Z TAFS)
ISSUED AT 613 AM CDT WED SEP 23 2026
SATELLITE IMAGERY SHOWS LOW CLOUDS EXPANDING ACROSS THE REGION,
SLOWLY WORKING CLOSER TO OUR NORTHERN TERMINALS. AS SUCH, I HAVE
INTRODUCED TEMPO MVFR VIS AND CIGS AT BHM, EET, AND TCL THROUGH
23/15Z TO ACCOUNT FOR THIS ACTIVITY. SHOWERS AND THUNDERSTORMS
REMAIN POSSIBLE THIS AFTERNOON, BUT CONFIDENCE IN COVERAGE IS
STILL NOT HIGH ENOUGH TO INTRODUCE IT IN ANY FM GROUPS AT THIS
TIME. OTHERWISE, EXPECT VFR CONDITIONS FOR MOST OF THIS TAF
PERIOD.

FIRE WEATHER
SCATTERED THUNDERSTORMS ARE EXPECTED THIS AFTERNOON, FOLLOWED BY
DRIER CONDITIONS ARRIVING THURSDAY EVENING AND CONTINUING THROUGH
THE WEEKEND. MINIMUM RELATIVE HUMIDITY (MINRH) VALUES WILL REMAIN
BETWEEN 40% AND 60% THROUGH THE END OF THE WEEK. HOWEVER, DRIER
AIR WILL BUILD IN OVER THE WEEKEND, WITH MINRHS APPROACHING
CRITICAL THRESHOLDS ON SATURDAY AND SUNDAY. WINDS ARE EXPECTED TO
REMAIN GENERALLY LIGHT AND EASTERLY.
