ST. LOUIS — A strong cold front will move across Missouri and Illinois Wednesday evening. Temperatures ahead of the front are well into the 80s perhaps even touching 90 degrees ahead of the front. While it's not as humid as it typically is during the summer, strong winds aloft will help thunderstorms develop along and ahead of the cold front.
Some of the storms are expected to produce strong damaging winds and large hail. The tornado threat is lower due to the lack of humid air near the ground. Farther southeast across southern Illinois and southeast Missouri, there may be a bit more of a tornado threat as humidity levels there are a bit higher.
