A strong cold front will move through the region on Thursday. Scattered thunderstorms are expected to develop ahead of the front during the afternoon and continue into the evening as the front moves southeast. A few storms could be severe and capable of producing damaging winds. A brief tornado or two is also possible.
Much cooler weather will move in Missouri and Illinois over the weekend behind a cold front. Other than some scattered showers over parts of northeast Missouri and west central Illinois on Friday afternoon, the weekend is expected to be dry.
Although frost is unlikely over the next week, we are approaching the time of fall that we commonly see our first frost and freeze. Plan ahead with the local fall frost and freeze climatology for select locations across the region. For more information, go to weather.gov/lsx/frostfreezepage.
