DISCUSSION

Issued at 1200 PM CDT Sun Aug 9 2026

The synoptic pattern set-up of high pressure aloft building over the South, while surface high pressure to the east keeps a pump of warm/moist return flow here, translates to dangerously hot/humid conditions for us the first half of this new week. HI's peak daily around/in excess of 100 degrees, and may climb upwards locally to near 110 degrees on the hottest days, Monday-Tuesday.

Storm chances return over the back half of the week. The best and most widespread chance, including strong storm chances, is Thursday, when a sharp, positively-tilted trof tracks from the Great Lakes to the Upper Ohio Valley. Best severe and heavy rain chances do appear to be closer to the synoptic center of the system, which would keep such chances mostly focused to our north and east.
