Skies will remain partly to mostly cloudy Monday night with high pressure in control over the Great Lakes. Cloud cover has been streaming into northern Illinois as low pressure moves through the South.
A cold front draped over Minnesota and Iowa has been the focal point for thunderstorms over central Iowa, but over the past several hours those have continued to weaken. Winds will turn light Monday night and with moisture still present in the atmosphere areas of patchy fog will be likely once again Tuesday morning.
Locally dense fog will be possible but it shouldn’t last too long after sunrise Tuesday morning. Skies will then turn partly to mostly cloudy for the afternoon with highs warming back near 80 degrees during the afternoon. The cold front currently located over Iowa will slide through southern Wisconsin and northern Illinois late Tuesday evening. This could bring an isolated shower to parts of the Stateline during that time, but most areas are expected to remain dry.
