A flow of arctic air will extend from eastern Canada to the Midwestern and Northeastern portions of the United States on Friday. Very cold air and moisture from the Great Lakes will allow flurries and heavier snow squalls to extend from the Great Lakes to New England and the central Appalachians. A few flurries may also develop east of the mountains in the Mid-Atlantic Region as well. Areas made wet by natural melting during the day may quickly freeze toward the evening. Pedestrians and motorists may discover patches of ice where large piles of snow remain in the wake of the big snowstorm.
Many areas from the Southeast to the Plains and Southwest can expect dry weather Friday. Exceptions will be spotty rain showers over the middle Mississippi Valley and coastal Texas. These rain showers will be the beginnings of a new storm. Cool conditions for the middle of March are forecast for the Southeastern states.
In the Northwest, a vast area of clouds and rain showers is forecast to extend from Northern California to Washington and western Idaho. Snow showers will occur in parts of the northern Rockies. A Pacific Ocean storm is forecast to move on shore with rain falling across much of California this weekend.
Focus: Cold Air to Persist in Northeast
The jet stream will dip south across the eastern United States, allowing multiple waves of cold air to drop in from Canada to the northeastern United States through the middle of next week. This will result in below-normal temperatures and multiple chances for snow.
