(Tyler Sebree/ABC 57) Our first major winter storm of the season begins early Monday, Nov. 11, and lasts through the early afternoon hours of Tuesday.
Berrien, Cass, La Porte, and St. Joseph Counties are under a Winter Storm Warning for 5-9” of snow with some easily seeing 8-12”. Everyone else is under a Winter Weather Advisory for a widespread 3-4” of snow with some seeing 5-8” closer to the lake effect bands.
Light showers will mix with and change to light snow late tonight into the pre-dawn hours of Monday. Light to occasionally moderate snow will fall everywhere Monday morning into Monday afternoon with lake effect snow then taking over by dinnertime. Areas who see the lake effect snow bands will see moderate to heavy snow with rates of 1-2” per hour possible. If you’re not in the lake effect zone, you are done with snow by late Monday afternoon.
Otherwise, it’s very cold with highs struggling to get to 30. It’ll be even colder Tuesday and Wednesday with highs in the 20s and lows in the single digits and teens.
A slight moderation in temperatures will occur by late in the week as highs get back to and above the freezing mark by Thursday. It’s possible we could see some light snow again late in the day Wednesday and Wednesday night, but that will likely be minor.
Monday: Steady system snow transitions to lake effect snow. Breezy. High of 30.
Tuesday: Mostly cloudy with lake effect snow showers. Frigid. High of 22.
Wednesday: Mostly cloudy with a slight chance of snow showers late in the day. High of 25.
