DISCUSSION

(This afternoon through Monday) Issued at 208 PM CDT TUE JUL 28 2026

Our area will remain in a northwest flow upper level pattern, on the eastern periphery of the big heat dome, through most of the rest of the work week. Weak disturbances in this flow regime could help kick off isolated/scattered showers and storms during this time. With the center of the upper high moving back to the west, afternoon temperatures the next few days should moderate some back down to more "typical" summertime levels. While the southern counties in our CWA may be close to Heat Advisory criteria, I don't think the confidence criteria exceedance is high enough to warrant an extension of the Advisory at this time.

As we transition to the weekend, the computer models are advertising a much more substantial shortwave trough digging into the southeast states from the north. This trough will further "cool" temperatures, and bring an enhanced chance of showers and storms to our area Saturday and Sunday. Beyond the weekend, it looks like that upper low just hangs around into at least early next week, keeping temperatures manageable and keeping rain chances a bit elevated.

AVIATION

(00Z TAFS) Issued at 601 PM CDT TUE JUL 28 2026

VFR conditions prevail throughout this TAF cycle. Light westerly winds tonight will become more northerly through the day Wednesday, generally from 8-10 knots. With that said, winds at AUO will be a bit stronger with gusts up to 20 knots at times during the afternoon hours. There is a low (20-30%) chance of showers and storms towards the end of this TAF window. As a result, a PROB30 group was introduced to account for this activity.

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

FIRE WEATHER

A warm and humid air mass will help fire weather concerns in check for the week. MinRH values are expected to remain above 50 percent through Wednesday. Some drier air begins to work in from the east on Thursday and Friday with RHs dropping to around 40%. However, winds will be light enough to negate any fire weather concerns.
