A storm taking shape over the Plains this weekend will strengthen and barrel through the Midwest and Northeast through the beginning of the week.
While some snow and an icy mix will fall over portions of the Dakotas during the day on Sunday, heavy precipitation is not expected to develop until Sunday night.
Accumulating snow will blanket a swath of southern Manitoba, Ontario, Minnesota, Wisconsin and Michigan.
Farther south, “cold air will become trapped near the surface in some locations for a period of freezing rain and slippery travel,” AccuWeather Meteorologist Brett Rathbun said.
Cities such as Minneapolis, Milwaukee and Detroit could become snarled with traffic as roads get slick, but Chicago and Des Moines will face no such problems as plain rain falls overnight.
The threat for wintry and icy weather will then spread eastward into the mid-Atlantic and New England through Monday morning.
“The greatest icing issues will be across Michigan during Sunday night and Monday morning and central Pennsylvania into upstate New York Monday afternoon and Monday evening,” Rathbun said.
The Monday morning commute could, therefore, be slower and more hazardous for many, even as far east as the Interstate-95 corridor.
Extra time, as well as extra safety precautions should be taken into consideration as workers head out the door that morning.
For many in this area, this event will start out with snow, sleet or freezing rain on Monday and end with warmer conditions and plain rain on Tuesday.
“Precipitation will be in the form of plain rain from New York to Washington, D.C. but it is expected to begin as snow in and around Boston for the Tuesday morning commute,” Rathbun said.
The storm is predicted to be more consistently wintry farther north.
“A general 3 to 6 inches of snow will fall from northern Minnesota to northern New England,” Rathbun said, since precipitation is likely to be just snow in these areas for the duration of this event.
The AccuWeather Local StormMax™ of 12 inches means skiers across New England can look forward to plenty of fresh snow by Tuesday.
Snow squalls and colder, blustery weather is expected for Tuesday and Wednesday, which could lead to further travel slowdowns.
