309 AM CDT THU AUG 20 2026
DISCUSSION
SHOWERS AND THUNDERSTORMS COULD IMPACT PORTIONS OF FAR NORTHERN
ALABAMA TOWARDS DAYBREAK. SHOWER COVERAGE OTHERWISE SHOULD WANE
AS WE GO INTO THE LATE MORNING AND AFTERNOON. BETTER CHANCES OF
THUNDERSTORMS ARE FORECAST LATER THIS AFTERNOON AND EVENING, AS
AN UPPER LEVEL SYSTEM NEARS. STRONG TO SEVERE WIND GUSTS AND
TORRENTIAL RAINFALL COULD ACCOMPANY THE STRONGER STORMS.
OTHERWISE OUTSIDE OF SHOWER ACTIVITY, EXPECT ANOTHER VERY WARM TO
HOT DAY ACROSS NORTHERN ALABAMA. HIGH TEMPERATURES SHOULD RISE
INTO THE LOW/MID 90S, WITH SOME HEAT INDEX VALUES GREATER THAN 105
DEGREES. MINIMUM AFTERNOON RELATIVE HUMIDITIES OF 50 TO 55
PERCENT ARE EXPECTED, ALONG WITH GENERALLY GOOD TO GOOD SMOKE
DISPERSION RATES.
FOG POTENTIAL OVER THE NEXT FEW DAYS: PATCHY FOG COULD OCCUR IN
MORE SHELTERED LOCATIONS EARLY THIS MORNING. ANY FOG THAT FORMS
SHOULD DISSIPATE SHORTLY AFTER SUNRISE.
POTENTIAL FOR RED FLAG CONDITIONS: NOT FORECAST AT THIS TIME.
