KEY MESSAGES

- Dangerous heat stress intensifies areawide this weekend through the middle of next week.

DISCUSSION

Issued at 232 AM CDT Sat Jun 27 2026

Today through next Friday...High pressure at both the surface and aloft will keep a grip on our forecast area this weekend and into next week. While this will provide some opportunity for the CWA to dry out after a pretty wet stretch of weather, it'll unfortunately bring about a pretty hot and humid stretch of weather across the region. Currently, the next best chance for rain doesn't come until Tuesday, and continuing into Friday, as disturbances caught up in easterly flow aloft affect the forecast area.

In the meantime, increasing heat stress will be the bigger story during this forecast stretch. Each afternoon, highs will warm into the low and middle 90s, except mid and upper 90s Monday and Tuesday. This, coupled with dew points in the 70s, will yield afternoon heat index values at and above the century mark throughout the forecast period. At the moment, Monday and Tuesday's heat indices look their highest as values could reach up to around 110F. However on Tuesday, and continuing through Friday, increased rain chances each afternoon during this time could have an affect on just how high heat index readings get. I'll continue to advertise these dangerous heat stress conditions in the HWO into next week. We will also evaluate on a daily basis whether or not, at a minimum, a "Heat Advisory" is needed for portions of the forecast area. /19/
