DISCUSSION

Issued at 159 AM CDT Tue Sep 8 2026

Summer continues to keeps its hold on our region. An upper level ridge over the southeastern U.S. and a return of southerly winds will push high temperatures today into the 92 to 99 degree range, and the 94 to 101 degree range Wednesday. Heat indices today will max out around 100 degrees, and Wednesday in the 100 to 110 degree range. If the model blend continues to produce these values, a Heat Advisory will likely be needed Wednesday for a portion of the PAH forecast area (fa). This will also be dependent on timing of potential clouds/precipitation Wednesday afternoon, which could tamp down these values, especially north.

As the upper level ridge weakens and moves eastward, models bring a slow moving surface cold front south toward our area late Wednesday. The front will slowly makes its way across the PAH fa Thursday into Thursday night. Along and ahead of the front, chances of showers and thunderstorms will increase and spread from northwest to southeast late Wednesday into Wednesday night. The greatest chances (75-95%) will be late Wednesday night through Thursday morning across southwest Indiana, southern Illinois and southeast Missouri, and through the day Thursday across west Kentucky and extreme southeast Missouri. Good chances (40-60%) will linger into Thursday night across mainly west Kentucky and portions of southeast Missouri.

SPC Day 3 includes southern Illinois, southwest Indiana and portions of southeast Missouri in a Marginal Risk, with the main concern with storms being gusty winds late Wednesday into Wednesday night.

The cold front will hang up to our south as a weak upper level trof lingers over the region. This will keep things unsettled Friday and the weekend, with on and off 20-40% chances of showers and storms.

The passage of the cold front will bring temperatures down to more seasonable readings Thursday and Friday. A return of southerly winds over the weekend will push high temperatures back up to around 90 degrees. Readings will then trend back down to more seasonable readings early next week.
