KEY MESSAGES

Issued at 1226 AM CDT SAT MAY 30 2026

- Periods of scattered to numerous showers and thunderstorms are forecast through the weekend, with low chances for isolated flash flooding or a strong thunderstorm.

DISCUSSION

(Today through Friday) Issued at 1203 AM CDT SAT MAY 30 2026

Tonight the upper flow will transition to a more west-northwest flow as an upper low shifts northeast into the Rockies, weak ridging develops northward from Mexico to across the Gulf, and a second large low feature cycles out of New England into the Atlantic. This will allow for the surface frontal boundary that we have been talking about the last few days to move back southward slowly across Alabama over the weekend. This movement will result in a continued high probability of convection for Saturday into Sunday with the focus of the meandering frontal boundary.

Low to moderate rain chances will continue behind the front for portions of Central Alabama on Monday through the week. While the first "low" moves out into the Atlantic over the weekend, the latest guidance breaks off a shortwave lobe from the Eastern Conus upper low and forms another low further south Monday into Tuesday. This will generate daily opportunities for disturbances rotating around this resulting system as it wobbles along the Eastern Seaboard leaving Alabama in an unsettled northwest flow scenario through the end of the extended.

AVIATION

(06Z TAFS) Issued at 1226 AM CDT SAT MAY 30 2026

Moisture continues in the pattern. All sites are currently VFR with convection limited to AUO, which is expected to dissipate by 8z. Conditions are expected to deteriorate through sunrise, dropping across Central Alabama between 8-10z, and reaching IFR/LIFR between 10-12z. A low to medium chance exists for patchy fog toward sunrise as temperatures cool toward dew points. Non- VFR cigs will likely linger until 17-18z. Issued a Prob30 of convection after 18z for all sites through 1-2z. Any heavier convection could result in lower IFR/MVFR conditions.

FIRE WEATHER

The persistent wet pattern is expected to continue through the weekend across Central Alabama. This pattern will lead to high rain chances each afternoon and the development of low clouds or patchy fog each morning. Therefore, there are no fire weather concerns at this time.
