DISCUSSION

Issued at 113 PM CDT Wed Jul 1 2026

Strong/broad high pressure firms its grip upon our sensible weather, creating prolonged extreme heat. Heat headlines continue thru the remainder of the week, and could be extended into the holiday weekend. However, daily rain chances reappear tomorrow, and slowly increase heading into the weekend and right on into next week. Current forecast heat indices flirt with Advisory levels, which if attained, would support a Warning extension for duration if they weren't so marginal. But since the HI's could fall shy, and seeing no broader consensus to upgrade, will stay steady-as-she-goes with our headline approach today, and potentially upgrade to warning later, or go with an Advisory headline vs a Warning. We'll see the modeled pops play out another 24-48 hours before deciding on how attainable warning vs advisory numbers pan out.

River flooding continues on the Wabash and Patoka and now Green, with Princeton pushing rare high water levels into Major category beginning tonight, before falling back to Moderate this weekend.
