KEY MESSAGES

* Scattered chances for showers and storms increase this weekend and into early next week. Temperatures and heat indices are expected to return to near normal during this timeframe.

DISCUSSION

Issued at 256 AM CDT Wed Jul 1 2026

High pressure at the surface and ridging aloft is centered over the lower Ohio Valley. Southerly flow around the high pressure has allowed for increased moisture and temperatures each day. Winds remain breezy overnight, which has limited the amount of radiational cooling each night. We continue to break warm minimum temperatures at climate sites each day. Low temperatures each day have been in the mid and upper 70s and this will continue. This places overnight minimum heat indices in the upper 70s and low 80s. This type of heat overnight is not providing any relief from daytime heat. During the day, heat indices have ranged from 103-108F (though some areas have reached as high as 112F). This heat is expected to continue through at least Friday, therefore, an Extreme Heat Warning continues.

Given the periphery of the ridge is located just to the northwest of the region, daily vorticity and weakening energy will move through far northwestern Missouri. Weakening showers and storms may move through this portion of the area each evening through the end of the week.

On Saturday, ridging begins to broaden out over the southern CONUS. Confidence in extreme heat is lower during this timeframe. Though some ensembles show a 50% chance of heat continuing through Saturday. Given uncertainty, the Extreme Heat Warning has not been extended into July 4th, however, we will monitor this closely.

With slightly weaker/broader ridging, daily shortwaves will move along the periphery of the ridge and bring scattered chances for showers and storms to the region this weekend and into early next week.
