The start of the workweek could feature the unexpected: the past week ends in sunshine and clear weather, and begins anew with snow.
The National Weather Service is forecasting up to 6 inches of snow in portions of Metro Detroit starting early Monday.
A low-pressure system moving through the northern Ohio Valley is expected to drop snow over the region starting at noon Monday and likely lasting all day, according to Ian Lee, a meteorologist with the weather service in White Lake Township.
A winter weather advisory is in effect until 4 a.m. Tuesday for Huron, Tuscola, Sanilac, Lapeer and St. Clair counties. For Oakland and Macomb counties, the winter advisory lasts to 7 p .m. Monday with accumulations of snow from 2-4 inches.
The service predicts a 100% chance of snow, but the amount may vary slightly.
“It is a tricky forecast. Even though we are close to the event, there’s still some moving parts in play right now,” said Lee.
Snowfall may affect travel, especially during the Monday evening commute. Slick conditions are possible, Lee said, especially if the snow begins earlier in the morning commute than expected.
Sunday weather will see highs in the upper 30s and lows in the lower 40s, with wind gusts up to 18 mph in the evening.
The rest of the week will get warmer, though not necessarily drier: rain showers are expected on Wednesday, Thursday and Friday, but Saturday’s high could pass 70 degrees.
