Prolonged Atmospheric River in the Pacific Northwest; Snow and High Winds from the Upper Midwest into the Northeast

A prolonged atmospheric river will continue to impact the Pacific Northwest into the Northern Rockies with heavy rainfall, areas of urban and river flooding, landslides, heavy mountain snow, and gusty winds into Thursday. A strong clipper system will bring the threat of heavy snow and high winds across the Upper Midwest/Great Lakes as well as portions of the interior Northeast and Appalachians. Read More >

Overview

On January 23rd, 2017 a winter storm moved into the northern plains. Initially this system brought freezing fog and patchy freezing drizzle to the area, creating a layer of light icing. Snow began moving in early on the 24th, and lasted into the next day. Nebraska, southern South Dakota, and the northern Black Hills received the most snow. In our area, the highest snowfall amounts reported were 14 inches in south central South Dakota. Breezy northwest winds created some areas of blowing snow, but generally winds were not very strong with this storm system.
