    Severe Weather Team 11 is tracking a complicated southern system that is currently forecast to push light snow into the area around sunset Sunday. Based on the most recent data, light snow will continue into Monday morning.

    Snow may complicate the morning commute Monday, and cold road temperatures will allow even just a coating of snow to create icy spots. Recent heavy rain has washed away any residual ice treatment left on roads and sidewalks, so plan now for possible delays.  

    Snow will mix with and change to rain in southern counties, limiting snow amounts. A wintry mix and straight snow will persist in northern locations, allowing for higher snow amounts there through Monday afternoon. 

    As always, this forecast will change as the system develops and moves closer to our area through the weekend. Stay with our team of meteorologists for updates, and check back often for the latest on Channel 11 News.
