Homeland Security Threat Level: YELLOW (ELEVATED)

Significant National Weather

Northeast
The last of the lake effect snow has ended, but a clipper system to the west will bring additional light snow to parts of northern New England by Saturday morning.
South
Most of the region will be dry and slightly warmer today. Rain and thunderstorms will move through much of the south on Saturday, followed by another surge of frigid polar air into the region Sunday.
Midwest
Light snow is forecast across most of Michigan and the Dakotas, with accumulations of an inch or two. Rain will develop throughout the Mississippi, Ohio, and Tennessee Valleys on Saturday. Snow will begin to intensify across the Upper Mississippi Valley, with moderate snow accumulations on Saturday. Minnesota and Wisconsin are forecast to receive from four to ten inches of snow. A more significant storm will affect the region late Saturday, with snow to the north and rain to the south. An arctic air mass is expected to move into the Midwest by Saturday evening, producing wind chills ranging from the single digits to minus 30 degrees across portions of North Dakota, Minnesota, Wisconsin, Illinois, and Indiana.
West
Lower elevation rain and mountain snow will diminish slightly today before a strong warm front moves into the Pacific Northwest states, reinvigorating moderate to heavy lower elevation rain and higher elevation snow as far eastward as the Central Rockies. Parts of western Washington and Oregon are expected to receive more than an inch of rain while the Washington Cascades could see a foot of snow. Flooding may occur in western Washington but the risk of flooding on the Green River downstream of the Howard Hanson Dam is considered low.
