Slight Chance of Showers Sunday

It will remain mostly clear overnight..... just a few high cirrus clouds overhead, and it will be seasonally cool with a low in the upper 30's. On Sunday a weak disturbance could cause some widely scattered light rain showers, but the temperature will turn out to be a little warmer than average with a high around 67 degrees. Scattered showers will continue on Sunday night, and the low will be a little above average... in the middle 40's. The disturbance will move east on Monday leaving skies mostly sunny, and temperatures will be pleasant... in the middle 60's.   On Monday night a warm front will lie from southern Illinois to an intensifying low over western South Dakota.   The warm front will move through the Stateline by daybreak on Tuesday as the low develops eastward into southwestern Minnesota.  Scattered showers are possible ovenight as the front moves through.  It will become quite breezy on Tuesday, and with the vigorous system moving through, there could be some thunderstorms with some gulf moisture being tapped.  The low will move rapidly to the northeast to a position over Lake Huron by early Wednesday, and colder air will follow in behind the front for Thursday, and the rest of the week.
