KEY MESSAGES

- Additional scattered showers and a few storms are possible early this morning before pushing east. Strong to severe storms are unlikely but the potential for flash flooding remains.

- Dangerous heat and humidity build into the region today and continue through the coming week. Heat indices up to 105 are expected on Sunday afternoon and between 105 and 110 Monday through Thursday. This heatwave may linger through the 4th of July holiday weekend, although confidence is lower.

DISCUSSION

Issued at 1232 AM CDT Sun Jun 28 2026

Radar is quiet this morning after an eventful and busy afternoon yesterday. We continue to watch for another band of showers developing this morning. Guidance has been in decent agreement on development taking place after 7-9Z tonight, although exact placement continues to be vary a bit. Increasing boundary layer convergence is expected to develop from NW to SE generally from southern IL, into southwest Indiana and parts of the Pennyrile. 20-25 knots of low level flow will continue to keep moisture transport ongoing. A maximum of PW is noted around 2.2 in over most of the area. Potential for heavy rainfall and training is a concern early this morning. While rainfall rates don't seem to be as intense, many of these areas have picked up several inches of rainfall with very saturated ground. Any additional rainfall could cause flash flooding. The current flood watch for W KY, S IL, and SW IN continues till 12Z.

Today sees a pattern shift taking place as upper heights build across the Quad State. Much of the rest of today should be rain free as this ridging develops. Much warmer temperatures are also expected with highs in the lower 90s. A heat advisory is in effect for the entire area today for heat indices at or greater than 105 degrees. Ridging expands for the remainder of the week with hot and muggy conditions. Highs reach into the mid to upper 90s through Friday. Dewpoints in the upper 70s will bring heat indices between 105 and 110+ degrees. Will continue with the excessive heat watch for now. No precipitation is expected until late week when guidance begins to suggest the ridge breaking down a bit and moving eastward potentially allowing for convection.
