Waves of cold air and moisture will bring the first snowflakes and snowfall of the season next week to the Great Lakes and central and northern Appalachians.
Meteorologist Dan DePodwin described the upcoming pattern as "a reminder that winter is on the way."
Mixed rain and snow and heavier snow showers can occur on multiple days next week.
States that are likely to catch their first glimpse of the white stuff this season include northeastern Illinois, northwestern Indiana, the western and northern Lower Peninsula of Michigan, northeastern Ohio, western and northern Pennsylvania, western Maryland, the West Virginia mountains, western and northern New York, the mountains of Vermont, northern New Hampshire and northwestern Maine.
Significant snow shower activity is not likely to reach the I-95 corridor. However, colder air will work its way to the coast in stages. After highs in the 60s Monday, temperatures will trend downward through the 50s later in the week.
Accumulating snow is most likely over the higher elevations of the Appalachians, parts of Michigan and northwestern Indiana, where a few inches are possible. Slow travel is possible over the highest elevations, especially along secondary roads with temperatures dipping into the 30s at times by day and the 20s at night.
It is possible that lawns and elevated surfaces in some valley and lower elevation spots get a light coating of snow.
Nearest to the shores of Great Lakes, warm waters make keep the air a bit too warm for all snow and perhaps any accumulation.
The snow for the lower Great Lakes and Appalachians follows the first snowflakes of the season for the Upper Midwest this weekend.
The first snow showers of the season will also fall over a large part of central and southern Ontario and western and southern Quebec next week.
