The Weather Channel reported this morning:

  • Another round of heavy lake-effect snow is underway. An additional 2 feet or more of snow is possible downwind of Lake Erie. Residents in “snow-paralyzed western New York are still trying to dig out from up to 65 inches of snow earlier this week.”
  • A 132-mile section of the New York State Thruway (Interstate 90) remains closed from exits 46 through 61 as of Thursday morning.
  • There are at least three separate snow bands moving across the country- from Lake Erie, Lake Ontario and Lake Superior/Michigan. “With time, the Lake Erie snowband should shift south out of Buffalo’s “southtowns” toward the [New York] southern tier counties.”
  • Major highways that will see the worst impacts from additional snow include I-90 from northeast of Cleveland to near Rochester (worst impacts near and just south of Buffalo); and I-81 north of Syracuse, including the Watertown, NY, area.

Arctic Outbreak

The Weather Channel also reports that another surge of cold arctic air is responsible for this second round of lake-effect snow across the Great Lakes snowbelts, affecting western and central New York, northwest Pennsylvania, northern Ohio, northern and western Michigan, and far northern Wisconsin.

There have been more than 400 record lows and record cool highs set, covering 43 states, since Sunday.

“With blocking high pressure aloft over eastern Alaska and northwest Canada, a direct pipeline of cold air will come from Siberia to near the North Pole, then southward into Canada and the U.S., particularly the Plains and Midwest. While not nearly as cold in magnitude, the arctic surges will also sweep into parts of the East.

This is a classic Arctic outbreak pattern that will remain largely locked in over these areas this week.”
