That is right. Your weather radio might get a test run Wednesday as we will see some thunderstorms passing through the area.
A cold front will start to move through the area Wednesday. Ahead of the front showers and thunderstorms will develop. Actually, the line of storms will most likely develop across western Missouri Tuesday evening. Below is a look at what Precisioncast was showing during last night's 10pm newscast.
Precisioncast was hinting at individual storm development moving through southeast Missouri around 6:00am CT Wednesday morning.
The Storm Prediction Center is keeping an eye on Wednesday as well. They have already included much of the Mississippi Valley in their day 3 outlook "Slight Risk" area.
