Tracking the return of heat and humidity, scattered storms

TONIGHT: Mostly clear and slightly warmer with lows in the upper 50s to around 60.

TOMORROW: Partly to mostly sunny and warmer with highs in the mid-upper 80s.

EXTENDED: We can expect our last cool night for the week as lows dip to near 60 for one more evening. Winds begin to shift to the southeast tomorrow, pulling in warmer, more humid air that sticks around through the weekend. Clouds increase on Friday night ahead of a disturbance moving through the upper jet stream along the northern edge of high pressure into Saturday. That will trigger a chance for scattered showers and a few storms on Saturday, especially before noon. The afternoon will be warm, but clouds will likely keep us under 90 degrees. Sunday will feature another chance for morning rain and a hot afternoon as highs get into the lower 90s. Next week, upper high pressure is parked over Mid-Missouri for the start of the week, bringing the heat index near 100 on Monday and Tuesday. A cold front moves through between Tuesday and Wednesday, dropping temperatures just slightly into the upper 80s.
