An arctic airmass is making its way through the Midwest and eventually the Northeast by the end of the work week. With record warmth temperatures experienced this fall, temperatures will feel 15 to 30 degrees below average. Additionally, the wind chill will make the temperatures feel even colder.
A series of storms will roll into the Western US this week. With each storm, a “Pineapple Express” moisture plume rooted near Hawaii will allow for heavy rainfall and mountain snow.
Following the first cold air outbreak of the season, a major winter storm will impact parts of the Plains, Upper Midwest, Great Lakes, and Northeast this weekend into early next week. Heavy snow will begin Saturday night with a mix of snow, rain, and ice working in as the storm tracks further east.
Relatively mild water temperatures between 40°F and 50°F in the Great Lakes will combine with a cold, arctic air mass to crank up the lake effect snow machine starting Wednesday night. And the machine will stay on through Friday afternoon, allowing for some places near the lakes to pick up not inches of snow, but multiple feet.
