This Afternoon: Partly cloudy and cooler in the mid-80s. UV index up to 7 - sunburn possible in as little as 30 minutes.
Tonight: Mostly cloudy and mild with light showers possible north of I-70 near sundown. Heavy rain arrives after midnight, becoming most widespread during the Tuesday morning commute.
Extended: Subseasonal conditions have settled over the region today as a cold front moved through over the weekend. This frontal boundary has now stalled out to our southwest along a ridge of high pressure, leaving Central Missouri with a pleasantly warm August afternoon. As low pressure tracks along this boundary tonight, it will interact with low-level winds to produce a soaking round of rain early Tuesday. It'll take until early Wednesday for the low pressure to clear out, and Mid-MO is set to receive 1-2" of rainfall during this event. Temperatures take a big hit this week with highs in the 70s Tuesday and Wednesday and we likely won't reach above the mid-80s all week.
