Monday's Weather Outlook

Frigid air entrenches the Central and Eastern U.S. as a historic winter storm comes to an end. 

Light to moderate snow will still be ongoing from our winter storm for the interior Northeast and New England. It will end west to east and will still be snowing into the next day for much of Maine. Three to 8 inches of snow will add totals on top of an already heavy snowpack. A rain/snow mix may occur much of the day for southern Rhode Island and Cape Cod of Massachusetts. 

As the most significant winter storm of the season exits off the East Coast, serious cold air will seep into the Eastern two-thirds of the nation. Low temperatures will be in the negatives and single digits for much of the Central U.S. High temperatures will not be much warmer with single digits, teens, and 20s from Missouri to Maine. 

Early in the morning, rain will end along the Southeast coast as a cold front sweeps the moisture out to sea. It will be dry and cool for the rest of the day. A few showers will move southeastward across Florida with a brief heavy downpour or two possible. 

In the Upper Midwest, a weak clipper will bring light snow to northern Wisconsin and Michigan. Further east, lake-effect snow prone locations off Lake Ontario and Lake Erie may see more snowfall accumulate. The snow band off Lake Ontario may be the beefiest with heavy snow falling under it. 

High pressure will bring dry weather to the Mid-Atlantic, Ohio Valley, Lower Midwest, Mid-South, and the Plains. In the Western U.S., more dry weather will occur for the Rockies, Four Corners, central to southern West Coast, Pacific Northwest, Great Basin, and Desert Southwest. However, a couple of showers cannot be ruled out for the Oregon and Washington coasts. 

Highs in the negatives and singles digits will be likely for the Midwest, Ohio Valley, and western Northeast. Teens and 20s will be felt in the eastern Northeast, New England, Mid-Atlantic, northern Plains, central Plains, and northern half of the southern Plains. The Mid-South, Tennessee Valley, High Plains, and high terrain of the Rockies will be in for 20s and 30s.  

Thirties and 40s are expected in the Deep South, Southeast, Great Basin, Four Corners, and interior Pacific Northwest. The northern to central West Coast and panhandle of Florida will see 40s and 50s. Fifties and 60s will take up the southern West Coast and Desert Southwest. The warmest air in the contiguous U.S. will be found in central to southern Florida with 60s and 70s.
