ST. LOUIS – We are playing a waiting game for thunderstorms. Temperature highs will be in the upper 70s. While an isolated storm Thursday morning north of I-70 can’t be ruled out, the focus of Thursday’s weather will be in the afternoon and evening.

A band of scattered strong storms is likely to develop in central Missouri early this afternoon and then spread southeast across the region this afternoon into this evening. The prime time for weather in the St. Louis area is from 3 p.m. to 7 p.m.

This is a level 2 out of 5 risk for severe weather. That is on the lower end of the spectrum, and lower than the Sunday event. However, there may still be some large hail and a few areas of wind damage. Even an isolated tornado is possible, but the risk is low.

Some dry time overnight and cooler air begins to settle in. Wake up temps Friday are set in the 50s. It’s going to be mostly cloudy, with a round of showers possible Friday. It’ll also be cooler, with highs in the 60s. 

Colder temps settle in for the weekend. Highs will be in the 50s Saturday and Sunday. Overnight temps will dip into the 30s. Sunday morning will be the coldest morning, with freezing temps possible away from the metro area. Frost is possible again Monday morning. You will want to protect sensitive plants.
