Dangerously cold air and gusting winds seized the Great Lakes and Northeast early Monday, while snow fell over the Midwest, Ohio Valley and Great Lakes.
Extremely cold air from the Upper Midwest was to keep the Northeast chilly and could produce considerable lake-effect snow downwind of most of the Great Lakes states. Wind chills well below 0 degrees could be commonplace throughout the area.
Significant snow was to fall from Wyoming and Montana through Wisconsin and northern Illinois. To the south, a mixture of rain, snow and sleet was forecast for the middle Mississippi Valley and Tennessee Valley. Ice accumulation was expected with up to a half an inch by Monday evening.
Areas of precipitation will continue in the Northwest and interior West, producing high elevation snow from the Cascades through the Intermountain West.
The Southwest and Southeast were to be warm and clear.
Temperatures in the Northeast were to rise only into the 10s, 20s and 30s, while the Upper Midwest should struggle to rise above 0 degrees.
The Southeast was forecast to have temperatures in the 60s and 70s. Temperatures in the Northwest will rise into the 30s and 40s, while the Southwest will see temperatures in the 60s and 70s.
Temperatures in the Lower 48 states on Sunday ranged from a low of minus-32 degrees at Bottineau, N.D., to a high of 85 degrees at Laredo, Texas.
