A sharp upper air trough will approach our area,  with its surface cold front moving through mid-day Saturday.  We will have a real taste of fall by late Saturday into Sunday.

Weekend Forecast Outlook

An unsettled weather pattern develops over the weekend, as a deep upper air trough in the middle of the country closes off over the Great Lakes and a cyclonic flow affects our area Saturday through the early part of next week.

The cold front associated with this upper trough moves through Saturday morning with some rain, ending about noon. The unstable cold flow aloft will bring windy conditions and instability cloudiness on Sunday.

Details on Friday.
