4Warn Weather – WINTER STORM WARNING: Monroe County until 12:00 AM Monday. This is where we are looking for the potential of the highest snowfall totals above 6″ by late Sunday night.
WINTER WEATHER ADVISORY: Livingston, Macomb, Oakland, Sanilac, St. Clair, Washtenaw, and Wayne Counties until 12:00 AM Monday, Sanilac County until 10:00 AM Monday. Snowfall totals of at least 3-4″ are anticipated through late Sunday night.
4WARN WEATHER ALERT: We are continuing our 4Warn Weather Alert as we go throughout the entire day on Sunday. Accumulating snow will make road conditions difficult to navigate as we work throughout the day and into the evening hours as well.

SUNDAY NIGHT: Mostly cloudy skies, a chance of snow. Low: 6.

After some sunshine to start the day on Saturday, the clouds quickly moved into the region, and snow has overspread the region overnight, and will continue as we look ahead through the end of the weekend. With a busy forecast ahead for the end of the weekend, and start of next week, here’s a breakdown of the current forecast:
SUNDAY: We are expecting another widespread accumulating snow, with some places seeing significant snowfall totals by the time we get to late Sunday night and early on Monday morning. This is all thanks to the winter storm that is gripping the eastern 2/3 of the United States. Expect this snow to increase in intensity Sunday afternoon through late Sunday night, which is where the bulk of the accumulation will be. Keep in mind, with air temperatures remaining in the low end of the teens, salt is not effective with where our forecast temperatures are.
Here’s where I am expecting snowfall totals to go by late Sunday night and early Monday morning:
Along and South of I-696 (Wayne, Washtenaw, Lenawee & Monroe Counties): 4 to 6, potentially 5 to 7 inches of snowfall is possible. Winter Weather Advisories are in effect for this part of the region; a Winter Storm Warning is in effect for Monroe County.
North of I-696 to South of I-69: 3 to 5, potentially 4 to 6 inches of snowfall. Closer to the high-end of totals in Oakland, Washtenaw, and Macomb Counties. Winter Weather Advisories are in effect for this part of the region through late Sunday night.
North of I-69: 2 to 4 inches of snow possible, 5 inches of snow at the highest end of the totals. This is where we do not have any active advisories as you work into Genesee and Lapeer Counties. The exception could be Sanilac County, where additional snowfall is possible late Sunday night into Monday morning with the lake-effect snow fetch kicking in.
The snow will stick around Sunday night into early Monday morning as a northwesterly flow kicks into the region, and we could see an additional light accumulation on top of what we are already forecasting throughout much of the day on Sunday.
Expect snow to stick around early Monday morning, before cloud cover persists for the rest of the day. Another round of snow showers moves in on Tuesday afternoon and into Tuesday evening, before another round of extreme cold moves in by the end of next week. That snow on Tuesday is thanks to another clipper system moving into the region, and that could leave a few inches of snow accumulation by late Tuesday night.
The frigid air mass will continue to grip the region through the end of the week. Overnight low temperatures starting Monday night through Saturday morning will be right around zero, if not into the low-end of the single digits. But, I am forecasting overnight lows Thursday night and into Friday morning to go back below zero. We could see at least a few more nights this week where wind chill temperatures will be in the territory where we may need another round of Cold Weather Advisories. We’ll be tracking that as we go throughout the next few days.
We do bring some quieter weather into the forecast for the second half of next week and into the start of next weekend. A mix of sunshine and clouds is expected on Wednesday and Thursday, then we bring more sunshine than anything else into the forecast from Friday, and into the start of next weekend on Saturday.
