Winter Storm Map Shows Every US State Weather Alert on MLK Weekend

Federal weather warnings or advisory notices are in place across large chunks of the United States, with expected to continue from Saturday to Monday, the Day federal holiday. A map shows winter storm warnings in place for nearly all of Oregon, as well as parts of Idaho, Nevada, Utah, California, Michigan, Nebraska and high points in Colorado.

Winter weather advisory alerts are also in place for those parts of northern Nevada not covered by storm warnings, along with areas in Washington, Wyoming, Maine and some mostly eastern parts of California. Further east, a wind chill warning covers virtually the entirety of Montana, North Dakota, South Dakota, Nebraska, Kansas and Iowa, along with northern parts of Oklahoma, Missouri and Illinois.

Weaker winter chill advisory notices are in effect for northern Texas, Arkansas, and predominantly southern parts of Illinois, Indiana and Ohio. A winter storm watch covers a swath of the southeast including nearly all of Tennessee, eastern parts of Arkansas and northern areas in Mississippi and Alabama.

Over the past couple of days, a storm that initially for western central states has been moving northeastwards, covering the NWS wind advisory alerts are in place for Pennsylvania, along with parts of West Virginia, Virginia, Washington D.C. and the Carolinas. Flood warnings or watches are in effect along a part of the eastern seaboard, including coastal parts of New Hampshire, Massachusetts, Rhode Island, New York, New Jersey and Delaware.

In its most recent update, released on Saturday at 3:28 a.m. EST, the NWS forecasts winter storms with a significant impact for the eastern half of the U.S., along with "heavy rain in the northeast" and along the West Coast. The NWS update says: "Our very busy weather pattern continues this weekend as an intense low pressure system yields significant wintry weather across the Corn Belt and Great Lakes today, with frigid Arctic air on its heels spilling southward from Canada.

"Bouts of snowfall on the back side of this expansive low, combined with wind gusts upwards of 25 40 mph will maintain blizzard conditions and dangerous to impossible travel across parts of the Corn Belt through the Great Lakes today even as the overall snowfall area associated with this system diminishes by later on this evening," the NWS update adds.

The forecast also warns of hazardous conditions as you head west: "Low temperatures approaching 40 50 below zero are not out of the question this morning over parts of Montana in the heart of the cold air, and numerous sub zero low temperature records could fall today and tomorrow over the Northern and Central Plains.

"Further west, heavy blowing snow and valley icing will all contribute to hazardous travel across the Great Basin and Pacific Northwest this weekend, where a swath of Winter Storm Warnings and Watches is in effect. Significant freezing rain is expected over Oregon today, with tree and power line damage possible."
