DISCUSSION
Issued at 114 PM CDT Mon Jun 29 2026
The potent upper level ridge continues to lock into place over the region today. Highs expected in the mid 90s with dew points in the upper 70s. This will lead to heat indices generally in the 105+ range. The ridge is expected to stay in place through late week, possibly into the weekend. An Extreme Heat Warning is in effect as heat indices remain in the 105+ range through Friday and possibly into Saturday.
By Thursday the ridge axis shifts more east and begins to potentially relax a bit. This introduces the chance for some isolated to scattered (20-30%) showers and storms over portions of the area during the afternoon and evening. Chances continue into the weekend as the ridge breaks down. PoPs pick up to around 30-40% Sunday afternoon as a shortwave moves through mainly to our north.
