KEY MESSAGES

Issued at 109 AM 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

(Wednesday through next Tuesday) Issued at 1033 PM CDT TUE SEP 1 2026

Water vapor imagery this evening reveals a stout upper level ridge expanding across the southeastern US as Tropical Depression Edouard continues to move slowly northwest across eastern Texas. Increasing subsidence will help maintain dry conditions across the area through the majority of the work week. With that said, we will continue with low (10-20%) chances for diurnally driven convection as a healthy plume of moisture remains in place across the region. We are not expecting much in the way of severe weather as wind shear will be minimal. However, instability will be sufficient enough to support a stronger storm or two as we reach peak heating. Low to medium (20-50%) chances for showers and storms return to the forecast for the southern half of the state late Thursday through the weekend as a shortwave rotates west along the southern periphery of the ridge.

Our increasing heat risk will be the main story over the next week. High temps will settle into the mid to upper 90s daily with heat indices pushing into the 105-108 degree range. This will promote a major to extreme heat risk for parts of Central Alabama daily as we head into the weekend. There were no changes made this evening regarding our current Heat Advisory. It remains in effect from 11 AM Wednesday morning through 8 PM Saturday evening. We continue to emphasize the importance of hydration and limiting outdoor exposure to mitigate the significant heat risk expected throughout the week.

AVIATION

(06Z TAFS) Issued at 109 AM CDT WED SEP 2 2026

Prevailing VFR conditions are expected through the TAF period with easterly winds of 4 to 6 knots. Very isolated shower/thunderstorm activity is possible between 18Z and 00Z, but confidence is too low for inclusion in the TAFs.

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.
