There is troughing aloft over the east while ridging shift to the Upper Midwest. With just a few remaining clouds over the far southeast portions of the area and light winds, expect the development of some fog this morning across portions of the area. Thanks to high pressure we should stay dry through Wednesday with the main activity to our east and southeast. Given the mainly clear skies for today, expect temperatures to come back up to the mid 80s. Expect this trend to continue tomorrow and Wednesday with highs in the mid-upper 80s and even a few 90s possible on Wednesday (40-60% in southern IL, 50-70% in SEMO).

On Wednesday general troughiness sets up over the Northern Plains and Upper Midwest while sfc winds turn back to the south. A few ripples through the trof bring back mainly afternoon precip chances Thursday through the weekend. Temperatures stabilize around normal through the weekend as well. However, with the return of mid 70s dew points, the heat indices will climb back into the 100-105 degree range on Sunday and kick off our next heat wave into next week. In the NBM the chances of hitting 90 on Sunday are 40-60% and 50-70% on Monday. In the LREF chances of heat indices greater than or equal to 100 are 40-50% on Monday.
