ST. LOUIS – An impactful round of storms is expected into the early hours of Saturday. This storm system could be severe, producing large hail, damaging winds, and the chance of a tornado.

As always with nighttime storms, make sure you have a way to get weather warnings while sleeping. This is a big heads-up for those with camping plans.

As of late Friday evening, only a few counties in our viewing area are under a thunderstorm watch. In the case of a thunderstorm warning, seek shelter immediately if you are not already indoors.

There are also some risks for tornadoes, but the likeliness of such a threat is low. However, winds could reach up to 70 mph.

Storms will exit around mid-morning Saturday. We’ll dry out and clear out a bit, with highs in the upper 80s. A front will settle to our south and could produce a few additional showers and storms Saturday afternoon and evening south of metro St. Louis.

A dry start to Sunday, then we’ll watch for more storms Sunday night into Monday morning. Sunday’s highs are expected to be in the mid to upper 80s.
