KEY MESSAGES

- Prolonged duration heat will develop the first half of the new week, with HI's flirting with or reaching into the triple digits daily thru Wednesday.

- A stormier pattern emerges over the back half of the week, with Thursday offering best precipitation and strength of storm chances.

DISCUSSION

Issued at 1212 PM CDT Sat Aug 8 2026

Some modeling suggests the presence of a weak area of low pressure slipping in the wake of the surface ridge's eastward departure may allow a small chance of a shower/storm across the area, particularly the southeast. We'll leave that mention in there as this morning's CAMs struggle with a fixed solution but all produce some minimal noise output with respect to pcpn into this early evening.

Warm sectoring takes over thereafter, as the broader upper high builds over the Gulf thru mid week. The resultant warm advection fetch manifests here with higher temps, higher dew points, and pushing headline HI's. While considering a duration Advisory for Sunday-Wednesday, the new 12Z NBM's numbers have returned more marginal around the century mark for Sunday, and convective chances increase Wednesday, so we're going to punt and focus on the Monday-Tuesday timing of best heat for headlines in potential future packages, should the numbers hold and warrant; for now we're mainly in the 100-105 range Monday-Tuesday.

Storm chances really climb toward the week's end, as a sharper long wave trof digs across the Great Lakes and pushes a cold front toward the Ohio Valley. Thursday looks to be the best such chance for storms, and any potential for stronger storms look best Thursday as well.

AVIATION /18Z TAFS THROUGH 18Z SUNDAY/

Issued at 1212 PM CDT Sat Aug 8 2026

Time/height cross sections suggest mid-high level bases early in the package in the developing warm sector environ. Isolated storm chances in the late pm/early evening should stay mainly south and east of the terminals, so will not be included with issuance but monitored closely should vicinity mention become necessary. Patchy fog may provide late night/early tmrw morning restrictions to vsbys, otherwise, a quick burn and lift to FEW-SCT MVFR bases is anticipated before their expiration during the planning phase hours of the forecast.
