KEY MESSAGES

- Additional chances for strong to severe thunderstorms exist Saturday and Sunday.

..Storm chances Saturday and Sunday

After a break tomorrow, additional weak embedded shortwaves under the building ridge will bring some rounds of showers and thunderstorms. Temperatures will be well above average for early September and there should be good instability to work with. The deep layer shear is not as strong this weekend as today, but at 30 kts could still be adequate for strong to severe storms. Machine learning has some low probabilities for severe impacts for the weekend time period, mainly in the 5 to 15 percent range. Still some uncertainty, but will have to watch for some active convective days this holiday weekend.

AVIATION /06Z TAFS THROUGH 06Z SATURDAY/

Issued at 1138 PM CDT Thu Sep 3 2026

Thunderstorms have exited the region. In their wake, MVFR to IFR ceilings are expected to develop overnight, along with areas of fog. The best chances for fog appear to be at KDVL, where there are already a few sites in the area reporting lowered visibility. Therefore, added FG with LIFR visibilities into the KDVL TAF for a several hour period Friday morning. Fog and MVFR/IFR ceilings will slowly improve at all TAF sites Friday morning. Thereafter, aviation impacts appear to remain low through the end of the TAF period.
