TONIGHT: Mostly clear and humid with lows in the lower 70s.
TOMORROW: Mostly sunny, hot, and humid with highs in the upper 90s. Heat indices between 105-107.
EXTENDED: The heat index tomorrow will land between 105-107 and will be highest on Thursday as a cold front to our north pulls in even more moisture during the day. We'll see highs approaching 100 degrees and a heat index between 105-110. A Heat Advisory is in effect for all of Mid-MO until Thursday at 9 PM. This is truly dangerous weather to spend prolonged periods of time outdoors, but the heat breaks on Friday as the front slides south and stalls out across west-central Missouri. There could be a couple of strong storms around or after sunset on Thursday, but with a lack of wind shear to support severe weather, we'll likely see a few heavy downpours and isolated gusty winds. Another round of storms is possible Friday night into Saturday along this frontal boundary, bringing a chance of rain early on Friday. Saturday will pose a greater threat for a few more strong storms towards afternoon and evening as the ingredients look more favorable. Rain amounts through the weekend will end up around 1" to 1.5". Showers and storms come to an end early Sunday, leaving us in the lower to mid-80s on Saturday and Sunday. Next week looks much more comfortable as we'll get under a northwesterly upper-level flow aloft. This keeps temperatures in the low 80s with lower humidity early next week.
