The remainder of the Thanksgiving holiday weekend will feature dramatically cooler changes in the weather for the East while more stormy weather moves into the Northwest. The Southern Tier will remain locked into a quiet pattern.
WeatherBug Meteorologist Addison Green has the latest in this exclusive WeatherBug National Outlook Video.
The same front that brought tumbling temperatures to the Upper Midwest and Great Lakes Friday has swept off the East Coast today. In its wake, the calendar will seem to flip ahead to mid-December, with highs in the 30s and 40s instead of the 50s and 60s from Friday. On top of the temperature change, gusty northwest winds will shave another 10 degrees off high temperatures with wind chills in the teens, 20s and 30s.
If that weren`t enough, cold winds blowing across the relatively warm Great Lakes will produce snow squalls and possible whiteouts in places like Erie, Pa., Buffalo and Syracuse, N.Y. Totals could approach 10 inches in the most persistent snow bands.
Winter will also be in full throttle in the Northwest. Several inches of snow will accumulate in the Idaho Panhandle and western Montana while showers pepper the valleys.
High pressure will protect the Southwest, Plains and Southeast from any precipitation and high winds. Phoenix, Dallas, Atlanta and Miami will all see plenty of sunshine.
While the northern Plains to Mid-Atlantic and Northeast stay chilled in the 30s and 40s, large stretches of the Southern Tier, Plains, central and southern Rockies, Great Basin, Southwest and California will warm into the 50s, 60s and 70s.
The typical cooler western spots will be the Cascades and northern Rockies with highs in the 30s and 40s.
The chilly weather will stay bottled up along the Northern Tier while tranquil weather continues to rule the Southern Tier to round out the extended holiday weekend.
A weak upper-level wave following the eastern cold blast will trigger a few snow showers from Minnesota`s Arrowhead into the eastern Great Lakes. Any accumulation will be less than an inch.
Most of the accumulating snow will wind down in the northern Rockies with just a few more leftover flurries along and south of Interstate 90 in Montana, Idaho and western Wyoming.
Otherwise, the cold weather will continue from the Cascades into the northern Plains and south through the Ohio Valley, Mid-Atlantic and Northeast with highs climbing into the 30s and 40s. A plethora of 50s, 60s and 70s will dominate much of California through the Central Plains to the Deep South.
