TODAY: The Excessive Heat Warning continues for most areas until 8PM on Sunday.

Clouds and a chance of some scattered storms will begin to move in during the early evening hours.
TONIGHT: A better chance of storms overnight as a cold front makes its way into Missouri. Temperatures to end your weekend will be cooler in the lower 70's to start a much cooler week.
EXTENDED: A chance of more widespread storms Monday morning and into the evening but expect noticeably cooler conditions as the cold frontal passage will finally break this heat and drop temperatures in the upper 80's with heat index values in the mid 90's. Tuesday and the rest of your work week look similar to Monday with cooler conditions, a chance of showers, and periods of sunshine. Monday morning will continue with that chance of storms into the evening hours. For additional weather updates follow @ABC17Stormtrack on Twitter.
