This is a fair weather warning of an event with a powerful and unpleasant blow that will bring winds and plenty of snow. Oh no, say it ain't so?

Another extremely powerful Nor'easter is rumbling across the central US bringing heavy snow and blizzard conditions to the Northern Plains and Upper Midwest and elevated to critical fire weather conditions across the rest of the plains.

There is an elevated fire weather risk in southwest California. Another coastal low will impact the Middle Atlantic and New England with heavy snow, gusty winds, and coastal flooding.

Widespread heavy snow is forecast from the Northern High Plains, the Great Lakes/Ohio Valley region and the Northeast as an occluded surface front tracks eastward. Along and ahead of the trailing cold front, showers and thunderstorms will develop from the western Gulf states north to the southern Ohio Valley and east into the Carolinas and Southeast. A wave along this frontal boundary will quickly transition this system into a
nor'easter, which will bring additional 6 to 10 inches west of the major Metro areas, with higher amounts possible, to portions of the Mid-Atlantic and the Northeast Wednesday and Thursday. Lighter snowfall is forecast for the Central Appalachians and back into the northern Ohio Valley and Great Lakes region.

The heavy snow and strong wind have created blizzard conditions yesterday across portions of the Northern Plains that have persisted through the overnight hours. Conditions will begin to improve this morning and afternoon from west to east as the front tracks eastward. Numerous Blizzard Warnings, Winter Storm Warnings and Winter Weather Advisories are in effect for the Northern Plains and Upper Mississippi Valley.

Behind the cold front, strong wind speeds and dry air will filter into the central U.S. This will lead to continued critical fire danger for eastern Colorado through much of Kansas and Oklahoma as well as the Texas Panhandle through Monday night, and an elevated to critical risk will remain on Tuesday. Red Flag Warnings are in effect, and High Wind Warnings are in effect farther north across western South Dakota, Nebraska, and Kansas, as well as eastern Wyoming and Colorado. Southwestern California is also forecast to have elevated fire conditions on Tuesday, as the western U.S. is generally expected to be dry over the next couple days before a low-pressure system approaches Wednesday evening. Rain will be possible from the central California coast northward to the Pacific Northwest.
