KEY MESSAGES

Issued at 1140 AM CDT THU JUN 25 2026

- Heat & Humidity: A significant warming trend begins late this week; heat indices are expected to approach or exceed 100 degrees daily from Friday through early next week. This will pose a moderate to major heat risk over the majority of the region.

DISCUSSION

(This afternoon through Wednesday) Issued at 1140 AM CDT THU JUN 25 2026

As we go through the afternoon, we're expecting a few showers and thunderstorms to develop across Central AL. Guidance hasn't shown much consistency on the location of any convective activity, but overall does indicate isolated to scattered coverage across the area due to a weakening remnant boundary across the area. As we go into the weekend and through early next week, the focus will shift to the potential for heat impacts across the region. Broad ridging builds in and strengthens into next week leading to daytime temperatures reaching into the mid 90s each day Sunday through Wednesday. Heat indices will run in the 100-107 degree range through the first half of next week leading to the potential for heat advisories as we get closer in time. Overnight low temperatures are forecast to run in the mid 70s to potentially upper 70s in a few locations, which will limit heat recovery for anyone without adequate cooling in place.

AVIATION

(18Z TAFS) Issued at 1140 AM CDT THU JUN 25 2026

VFR conditions expected through the next 24 hours. With weak forcing in place, the coverage of any afternoon shower and thunderstorm development looks to be low. I'll maintain Prob30s for TSRA at EET, MGM, and AUO given trends in latest guidance, but confidence remains low. If any shower activity moves over a terminal, that location could see a temporary drop in VIS due to isolated fog development in the early morning hours. However, given the confidence is low for any shower activity, I'll hold off mentioning the lower VIS in any TAF site.

Note: AMD NOT SKED will continue for the AUO TAF until data issues with observations are resolved.

FIRE WEATHER

Isolated to scattered rain chances will persist today, but conditions generally become less favorable for wetting rains through the weekend. Heat and humidity will be the main story over the weekend and into early next week as heat indices approach and top 100 degrees. Fire weather impacts are not anticipated as the humid air mass builds in.
