Current model data continues to push towards a winter storm impacting the region beginning Sunday night through much of Monday and even into the first part of Tuesday.
A strong clipper-type system will be moving southeastward towards the area late Sunday night and develop areas of light snow initially shortly after sunset. The intensity of the snow is expected to increase by late Sunday night and into Monday morning with a few inches of accumulation likely. Light snow will continue throughout the day Monday adding a few more inches to accumulation totals.
Right now it appears likely our snowfall totals here in the Sauk Valley will fall in the 4-7 inch range with isolated higher amounts, especially further north.
Winds will increase on Monday which may allow for some minor blowing and drifting snow. Travel is expected to become difficult on Sunday night and through much of the day Monday.
Some type of advisory is likely to be issued by the National Weather Service over the next 12 hours or so.
