Strong winds will be possible with a passing low pressure system on Friday, but another system will pass overhead Sunday into Monday. The positioning of this system will bring more widespread precipitation, including a potential for some very heavy snow.
It will also bring a period of stronger winds, but not quite as strong as Friday's. The winds are driven by an increase in pressure gradient, driven by the difference between the low pressure overhead and higher pressure filtering in behind it. Peak wind gusts may be near 30 mph at times Sunday and Monday.
This weather system will also come with quite a bit more precipitation than Friday's. There is a potential or some very heavy snowfall across parts of Minnesota and Wisconsin. The axis of very heavy snow will likely remain just North of the Stateline, with more of a mix of rain and snow across far Northern Illinois and primarily rain to the South.
