- Rain chances increase through Friday, with higher chances for showers and thunderstorms each afternoon.

DISCUSSION

(Today through Wednesday) Issued at 1203 AM CDT THU AUG 27 2026

The radar is clear across Central Alabama at this time. However, there is a cluster of storms over MS moving SEWD through the upper NW flow. In the upper levels we continue with a large ridge AZ/NM and into NRN Mexico and upper over ERN Canada extending SWD into ERN Conus. This convection is expected to for the most part go over MS and into portions of SRN AL. Hires guidance does show a scattering of possible returns over the next few hours across Central AL, generally S of the surface boundary (SRN half of Central AL). Best chances for the remainder of the night will be across our SW counties. With some more meanderings of our surface boundary today expected, our best chance of storms both Thursday and Friday will be across the S/SE portions of the area as another wave/disturbance comes through the NW upper flow and around the base of the E Conus trough. Although our surface boundary is expected to fizzle out on Thursday, another boundary will quickly move in to replace it from the NW on Friday. Upper ridging is expected to expand EWD to much of the SRN US over the weekend. This in conjunction with surface ridging building across portions of the SE US will suppress some of the more widespread convection this weekend into the remainder of the extended except for the more isolated diurnally enhanced storms from the heat of the day. We will not be looking at heat advisories just yet, heat indices will begin to creep back up as we progress through this weekend and into next week.

AVIATION

(06Z TAFS) Issued at 1234 AM CDT THU AUG 27 2026

The stalled boundary has shifted slightly south, changing the main area of thunderstorm interest for today. EET, TCL, and BHM will carry PROB30 groups for TSRA, where MGM and AUO will carry TEMPO groups through 27/24z. IFR/LIFR conditions are also expected through 27/16z due to weak mixing and recent heavy rainfall.

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