KEY MESSAGES

- Scattered showers and storms into Saturday. The probability for severe storms is very low.

- There is a medium chance for thunderstorms early next week. Potential exists for strong to severe storms.

..Severe Potential Early Next Week

As another stronger wave propagates through Canada greater instability will advect into the region, ahead of a cold front. Multiple scenarios exist regarding how this will evolve, including strength and timing differences, which will ultimately decide on storm coverage and intensity - severe potential. ML/AI guidance indicate a signal for severe storms Monday-Tuesday.

AVIATION /18Z TAFS THROUGH 18Z SATURDAY/

Issued at 1256 PM CDT Fri Aug 14 2026

Aviation challenges through this period will be timing shower chances and the potential for MVFR cigs to develop. Wind direction will be switching Saturday morning as well. Given that the shower activity will be scattered in nature (on and off) makes forecasting for each TAF point more challenging, so went with mainly prob30s during the most likely periods of scattered showers. Most guidance indicates MVFR cigs developing Saturday morning, and although uncertainty exists this will happen, confidence is increasing.
