ST. LOUIS - Thursday will bring mostly sunny skies and a typical August feel.

Highs will climb into the low to mid 90s Thursday with noticeable humidity, bringing heat index readings closer to 100 F. In the heat of the afternoon and early evening, we may see a few showers or weak thunderstorms pop. Any isolated storms that develop will quickly fade near sunset. Overnight lows drop into the mid-70s.

Friday will bring similar conditions with temperatures again in the low to mid 90s with heat indices near 100 F. Rain chances should stay north of the region Friday and Saturday.

There is some uncertainty as to rain chances Saturday evening into Sunday but the focus for this looks to be across northeast Missouri into west-central Illinois.

Rain chances increase farther south into our region by Monday as a cold front tries to push into the area.
