Following a beautiful Tuesday afternoon, the weather turns a little more active Wednesday through Friday. High pressure slides to the southeast late Tuesday night and Wednesday morning, allowing a warm front to inch closer to the Great Lakes.
Right now it looks like there are two potential periods for heavy rain. The first arriving Wednesday evening/night and the second late Thursday through Friday morning. Rainfall amounts anywhere from one to three inches of rain will be possible over a three day span. Highest rain totals may be centered more over west-central Illinois, southeast Iowa and northern Missouri.
Because of the strong winds that will be taking place a few thousand feet above the surface of the earth, thunderstorms late Wednesday do have the potential to produce gusty winds with them. This threat would likely be during the afternoon Wednesday and Wednesday night. Stronger thunderstorms are also possible Thursday - right now mostly for our southern counties of Whiteside, Lee and DeKalb.
