Accumulating Snow Tonight Into Saturday Morning

Overnight Forecast November 16-17, 2018

An Alert Day is in the forecast overnight and into Saturday morning. An Alberta Clipper system may bring 1-4" of snow accumulation during that time. Some freezing drizzle at the onset of the snowfall is also possible, perhaps resulting in slippery road surfaces.

Skies will be mostly cloudy tonight as light snow develops and moves through southern Wisconsin. The snow should end early on Saturday morning, with skies possibly clearing in the afternoon. Total snow accumulations of 1-4" inches are possible, with the highest totals over southwest Wisconsin, and the lightest totals north and east. It will be breezy and colder with high temperatures falling back to the lower 30s. Sunday will be mostly sunny and cold; high temperatures will be near 30 degrees.

Cold weather will continue into early next week. Monday will be partly sunny with high temperatures in the lower 30s, while Tuesday will be partly sunny; high temperatures will be in the middle 30s.

Temperatures will moderate to near-normal by Thanksgiving Day. Wednesday will be partly sunny and not quite as cold; high temperatures will be near 40 degrees. Thanksgiving Day, skies will be partly sunny and a little milder; high temperatures will be in the middle 40s.

Black Friday will be mostly cloudy and breezy with scattered showers; high temperatures will be in the lower 40s. As a cold front sweeps through southern Wisconsin, it will turn colder in the afternoon and temperatures will slowly fall into the 30s later in the day. Rain showers may mix with or change to snow showers before ending at night.

For the rest of the Thanksgiving weekend, skies will be partly sunny Saturday and it will be colder; high temperatures will be in the upper 30s. Expect mostly cloudy skies and cold weather for Sunday with a chance of rain and snow showers; high temperatures will be in the upper 30s.
