Tracking Atmospheric River in the Northwest U.S. and Clipper with Winter Weather in the Northeast U.S.

A prolonged atmospheric river will continue to bring gusty winds, heavy rainfall which may lead to urban and river flooding with possible landslides, and heavy inter-mountain snow over the Pacific Northwest into the northern Rockies through Thursday. A clipper will cross the Great Lakes and Northeast U.S. into Thursday with areas of moderate to heavy snow and mixed wintry precipitation. Read More >

 

Light snow accumulations are expected in parts of southwest Virginia and the East TN mountains today through Thursday morning, mainly for elevations at or above 2500 ft. 1 to 3 inches are possible, with higher amounts on the highest mountain peaks.
Winds will increase with time today, first beginning in the mountains and then translating to the lower elevations. Gusts will persist into the overnight hours across the higher terrain before dropping off later Thursday. A Wind Advisory is in effect for gusts up to 45 mph.
Gusty winds can be expected today along with a few rain showers. The rain showers will transition to snow showers and flurries as colder air pushes in behind the front, with accumulating snow expected mainly across the higher elevations of the mountains. The snow showers and flurries will end Thursday, with dry conditions then expected into Friday.
