KEY MESSAGES

- A significant heat wave continues across our region, and an Extreme Heat Warning remains in effect through Friday evening.

- Isolated showers and thunderstorms (15-20% chances) are possible this afternoon across mainly southeast Missouri, southern Illinois and west Kentucky.

- A stray shower or storm is not out of the question Friday, but better chances (30-50%) arrive late Friday night and continue through the Independence Day weekend and into next week.

- Heat and humidity will persist into the weekend, but the gradually increasing chances of showers and thunderstorms and additional clouds may help bring down temperatures by a couple degrees. An extension of the heat headlines is possible.

UPDATE

Updated aviation section for 12z TAF issuance.

DISCUSSION

Issued at 242 AM CDT Thu Jul 2 2026

Hot and humid conditions will continue today and Friday with heat indices of 105 to 112 degrees. There are small chances (15-20%) of showers and storms this afternoon, but these will do little to mitigate our high temperatures in the middle 90s. Friday now looks to be mainly dry, so high temperatures will again reach the middle 90s.

The upper ridge gradually breaking down and pushing farther east will allow shower and storm chances to increase over the weekend to 25-50%, especially during the daytime hours. Just how much this will tamp down temperatures is in question, and heat index readings around 105 degrees or higher are still likely. Extensions of heat products into the weekend are possible, but for now we will hold off until we get a better handle on overall precipitation coverage and accompanying clouds. Shower and thunderstorm chances the first half of next week look to be associated with a frontal boundary slowly sinking south into our region. This will help bring temperatures down toward more seasonable readings and potentially slightly less humid air.
