More snow, lake effect to accumulate in the Midwest, Northeast into Thursday
The parade of clipper storms packing steady snow, snow squalls and lake-effect snow will continue in waves from the Midwest to the Northeast into Thursday.
Ice coverage on the Great Lakes is rapidly expanding, and the trend will increase later this week as the coldest air of the season makes its way into the region.
A series of clipper storms from western Canada is expected to bring additional snow and shifting bands of lake-effect snow with gusty winds into the northeastern quarter of the United States into Thursday.
Snow showers will extend from Michigan to the northern Appalachians, including the Adirondacks and New England, but they will be spotty or diminish to flurries by the time they reach the Northeast coast. However, some heavier snow showers can still reach the coast of Maine.
One clipper storm finished up in the Northeast Monday night as snow squalls diminished, but lake effect persisted off lakes Erie and Ontario. Lake-effect snow associated with the clipper storm was likely a factor in a large multi-vehicle crash in Michigan on Monday morning.
Another clipper will move across the Great Lakes and Northeast into Thursday, bringing snow and snow showers, while another clipper not far behind is expected to move southeastward from Canada Thursday.
As the system drew some moisture from the Great Lakes, snow fell from parts of West Virginia and western Pennsylvania into central and northern New York, as well as New England Wednesday night.
As was observed with earlier lake-effect activity, intense and persistent bands may produce 6-12 inches of snow in localized areas from western Michigan to western and northern New York. Total lake-effect snow for this week may exceed 3 feet in some of the most persistent bands from Monday to Thursday.
Even a brief snow squall producing a quick coating of snow can create dangerous conditions on highways and lead to deicing operations at area airports.
Locally intense lake-effect snow is likely Thursday night to Friday with frigid air moving in across the Great Lakes.
Some of the lowest temperatures of the season so far are expected to accompany the clipper pattern. However, an even stronger surge of cold air is anticipated from late this week to this weekend. That brutal surge of Arctic air will accompany and follow a massive storm with snow and ice for the southern and eastern part of the United States.
