…a broad swath of significant snowfall, extending from the Colorado Rockies to Wisconsin where winter storm watches and warnings are currently in effect.
…very windy conditions are likely across much of the Plains, with high wind watches in effect for the Texas and Oklahoma panhandle as well as adjacent portions of neighboring states.
An even stronger storm is expected to develop over the eastern Pacific and reach the West Coast by Tuesday night. … It should reach land near the California/Oregon border early Tuesday night and then begin to gradually weaken as it moves inland. The mountains of southern Oregon and northern California are likely to get hammered with blizzard conditions, and battering surf and high winds for coastal areas. Winter storm watches and warnings are already in effect for many of these areas, and the cold nature of the event will result in lower than usual snow levels.
Pre-Thanksgiving travel in this region could be severely affected, and local forecast offices have additional information pertaining to this.
