KEY MESSAGES

Issued at 1248 PM CDT WED SEP 2 2026

- Significant Heat Risk: A warming trend will push heat indices to 105-108 each afternoon into the weekend. A Heat Advisory is now in effect through 8PM Saturday.

DISCUSSION

(This afternoon through Tuesday) Issued at 1248 PM CDT WED SEP 2 2026

The headline event for central Alabama's weather through the rest of the week will continue to be the heat. Upper level heat dome centered just to our north will continue to help get air temperatures well into the 90s each afternoon, with heat indices topping out near or above 105 degrees. Ongoing Heat Advisory looks good. One thing to watch is another tropical wave that is forecast to scoot westward across northern FL and along the Gulf coast Thursday night into Saturday. This feature will likely bring higher rain chances to our southern counties during this time frame, which may also allow us to trim back the Heat Advisory area. Will keep the status quo for now, and reevaluate the Advisory if/when confidence in the rainy scenario increases.

As we head into Sunday, the center of the upper ridge heads back to the west, and puts us back into a north/northeast flow regime. This should allow POPs to climb back up to at least climo levels, and also temper the heat a bit into early next week. However, the models are coming into agreement that the upper ridge will shift back eastward in the Tuesday/Wednesday time frame, suggesting that the excessive heat may not quite be over for us.

AVIATION

(18Z TAFS) Issued at 1230 PM CDT WED SEP 2 2026

Will maintain a VFR forecast across central Alabama terminals over the next 24 hours, with daytime cumulus and nighttime clear skies. Rain chances remain very low to zero, and foresee no need to add any mention of convection to the forecast.

Note: AMD NOT SKED continues for AUO due to a weather observation outage.

FIRE WEATHER

Minimum RH values will generally remain above 40% through the work week. Low (10 to 20%) chances for showers and storms will continue daily. 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.
