KEY MESSAGES

Issued at 145 PM CDT SAT AUG 8 2026

- Summer Pattern: Scattered showers and thunderstorms will persist through the weekend, with locally heavy rainfall likely under high moisture and slow-moving storms.

- Heat: Humidity will push heat indices into the 97-104 degree range this weekend into next week, resulting in a moderate heat risk across Central Alabama.

DISCUSSION

(This afternoon through Friday) Issued at 145 PM CDT SAT AUG 8 2026

Scattered afternoon showers and thunderstorms will remain in the forecast through the weekend, as this typical summertime pattern is expected to continue. PWAT values remain quite high, so locally heavy rainfall is expected with slow storm motions. The upper-level pattern will slowly begin to break down by Monday, as the ridge to our east starts to become more suppressed by the trough to its north. At this time, the ridge appears to slide west, reestablishing itself along the Gulf coast, remaining over the Gulf Coast through Wednesday. It will begin to break down once more by Thursday, as the trough to our north drops south once again. Generally, this will keep rain in the forecast, but limit it to the diurnally driven afternoon activity. More organized rain activity is possible as the trough drops south next week, but confidence here is low since the best rain chances would be tied to the location of the trough.

Afternoon high temperatures will continue to run in the low to mid-90s, with the overall moisture content in the atmosphere remaining high. Because of that, afternoon heat index values will continue to reach triple-digits, but below heat headline criteria at this time.

AVIATION

(18Z TAFS) Issued at 1242 PM CDT SAT AUG 8 2026

Most terminals are once again carrying PROB30 groups for TSRA, as this summertime pattern is expected to continue. Given that this activity is diurnally driven, activity should decrease past 09/01z. Low CIGs are possible between 09/08-14z at EET and AUO, but low confidence will result in leaving the low CIGs out of any FM groups at this time.

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

FIRE WEATHER

Warm and humid conditions will help keep MinRH values generally above 50% through the week. Isolated to scattered showers and storms are expected daily. Because of this, elevated fire weather concerns will remain low over the next seven days.
