Clipper to drop snow over 2,000 miles

The finale of the last several weeks of cold shocks to the eastern two-thirds of the country is inbound this weekend through early next week. It’ll bring another round of snow on the front end and widespread deep cold, along with some records for chill, this weekend and into early next week.

Weather Watch

Long-tracked clipper. The latest in a series of fast-moving storms out of western Canada is set to dive southeast across the Lower 48 this weekend on the front end of an Arctic intrusion. Like most clippers, this one will be moisture starved, so snowfall totals won’t be too impressive — a general 2 to 5 inches, with some locations seeing up to half a foot or so. However, it may drop a rather continuous stripe of snow from Alberta Province to the Appalachians, then curving northeast toward Southern New England, a path of nearly 2,500 miles.

Another Arctic blast. An extreme cold warning is in place for parts of the northern Plains Friday morning for wind chills to minus-40. High temperatures only make the single digits above or below zero in that region today, and the cold slides southeast this weekend. It's a similar story in the Upper Midwest and as far south as the Chicago area Saturday -- that city is forecast to have a high of 7. By Sunday and Monday somewhat modified air reaches the East Coast with highs in the 20s and 30s as far south as the Carolinas. Overnight lows will fall as far as the minus-20s in the Dakotas and Minnesota.
