Weekly Highlights December 7th to 13th

This week’s weather will be shaped by a steady parade of clipper systems dropping out of Canada and sweeping through the Plains, Midwest, Great Lakes, and eventually the Northeast. The first clipper arrives Sunday, spreading snow across the Plains and into the Great Lakes to start the week. This sets the pattern going forward, with several additional clippers expected to follow the same track. Most areas affected by these systems will see 1 to 4 inches of snow, but parts of the Plains and Great Lakes—including regions closest to the lakes—could see totals climbing above 4 inches as the week progresses. Interior portions of the Northeast will also pick up bursts of lake-effect snow between clippers, adding to the snowy theme in the eastern part of the country.

Farther south, a different weather story unfolds. Florida will see showers and thunderstorms on Sunday, bringing a round of active weather to the region before conditions settle down midweek. Meanwhile, colder air filtering in behind the first clipper will allow snow to push unusually far south into the Carolinas on Monday. Accumulations of 1 to 4 inches are expected.

Out west, the Rockies will continue to see additional snowfall as multiple disturbances bring fresh rounds of moisture and cold air to higher elevations. By Friday, attention shifts back toward the central U.S., where showers are expected to develop across the Tennessee Valley, closing out what will be a very active and wintry week for much of the country.
