A mixture of rain and snow came down Sunday afternoon before switching over to mostly snow Sunday evening. As low pressure moves further east cooler air will settle into northern Illinois and southern Wisconsin, bringing temperatures down into the 20s by Monday morning. Light snow will continue to fall across much of the area through Midnight, with flurries lasting into early Monday morning.
A few heavier bursts of snow did allow some of it to stick to grassy surfaces and trees, but no accumulations are expected on the roads locally. Visibility has also fallen with a few places reporting two miles, or less, Sunday evening. As drier air moves in from the North during the night the snow will taper off to flurries by Monday morning. There might be a little freezing drizzle mixed in before sunrise, but the chance for that appears to be fairly low. Temperatures will dip down into the mid/upper 20s for the start of Monday and this could lead to a few slick spots, especially on untreated and elevated surfaces. Sunshine should make an appearance by Monday afternoon before clouds move back in Monday night.
