Flash freeze, wintry mix, and strong winds Sunday night

 Sometimes to get out of a cloudy and foggy pattern like we have seen lately, you need a strong weather system to kick the moisture out. We will have such a system this weekend that will eventually bring some drier air, but it also comes with a strong push of colder air.

Clouds will remain thick throughout Saturday afternoon, not allowing temperatures to rise above the mid-40s yet again. Light showers may arrive by late Saturday evening, but steady rain will make an approach toward daybreak Sunday. Temperatures may even approach 50 degrees early Sunday for a few spots, especially South of I-88.

Light to steady rain looks most likely through mid-day before a bit of a lull in precipitation Sunday afternoon as the low pressure center passes directly overhead. All told through Sunday evening, most in the Stateline may be able to see between 0.25-0.75" of rainfall, with the higher end of that range likely toward I-88 and South.

Big changes sweep through behind the passing low pressure system, with a much cooler air mass taking the place of the mild and damp one we have seen lately. The arrival of the cold air may also allow for a flip over from rain to a mix or snow Sunday night, with pockets of snow showers carrying over into Monday. As of now, a dusting of snow is possible locally with potentially accumulating snow in parts of Wisconsin.

The flip over to snow also comes with crashing temperatures and strong winds from the Northwest. Gusts may reach 35-40 mph at times Sunday night into Monday morning. This could limit visibility significantly if we have any falling snow during that time.

Temperatures may be nearly 50 degrees early in the day Sunday but could fall to the teens by Monday morning. This will cause any moisture on roadways to freeze over quickly, with several slick spots likely Monday morning. Any falling snow Monday morning will only make for more of a headache, so plan for extra time commuting anywhere Monday! Temperatures will remain below freezing the rest of the week to follow, and another strong cold front New Year's Eve will push afternoon highs toward the teens to start the new year.
