DISCUSSION

Issued at 104 PM CDT Sat Aug 1 2026

High pressure will continue to be in control of our weather over the next week. As mentioned previously, the eastern flank of the ridge will weaken due to a strengthening trough, which will increase moisture into the area. PWATs are anticipated to reach 2" as moisture pools ahead of a weak surface reflection of this trough. As this moves south, a low (15-25%) chance of showers and thunderstorms will develop Sunday before drier air moves, effectively ending our rain chances for the upcoming work week.

Temperatures will remain hot through the upcoming week. Heat index values will range from 105-109, with isolated locations reaching 110- 113. While this already sounds miserable for anyone outside, a better indicator of heat-related impacts is the WetBulb Globe Temperature (WBGT), which takes the sun angle, latitude, temperature, sky cover, wind, and moisture into account. For this weekend through the upcoming week, WGBT is generally extreme, though a few locations will "only" be high. This means for every hour you spend outside, you should take a 20 minute break.

AVIATION

(00Z TAFS) Issued at 634 PM CDT Sat Aug 1 2026

Generally VFR conditions will prevail through the TAF period, although there is a medium chance (around 40%) of MVFR cigs/visibility at KALI/KCRP Sunday morning. There will also be isolated-scattered showers and thunderstorms during the day on Sunday, so some mention of TSRA may be needed in future TAF issuances if probs increase. Winds will trend light and variable overnight and likely remain light and variable through much of the day on Sunday, outside of any potential thunderstorm outflows.

MARINE

Issued at 104 PM CDT Sat Aug 1 2026

A gentle to moderate onshore (largely S-SE) flow can be expected through the forecast period, with occasional fresh winds during the overnight and morning hours. Seas will generally range from 2-4 feet through the forecast period. The only appreciable rain chances in the period will be on Sunday and even then chances will only be around 20%.
