DISCUSSION

Issued at 322 AM CDT Tue Jun 23 2026

A stalled frontal boundary remains stretched west-east across our forecast area earlier this morning. Overnight convection has mostly spread west and east outside of our CWA boundaries, but rain remains possible along it. And a few thunderstorms may re- develop with heating south of the boundary this afternoon. A complex or two of thunderstorms is expected to develop along the front in the broader region Wednesday, spreading into our forecast area during the day. There is a Marginal Risk for severe thunderstorms Wednesday associated with this possibility.

Through Thursday, the threat for dangerous heat will remain more "Limited" in nature - southern areas seeing heat index up to around 105 degrees. The heat will tick upwards for Friday/Saturday and especially by Sunday/Monday when heat index values are expected to reach above 110 degrees for portions of the area. Be sure relatives and neighbors have cool places to stay this week. /NF/
