Storm Impacting the Northwest U.S.; Fire Weather Conditions in Southern California; Severe Weather in the South

A Pacific storm is bringing areas of low elevation rain, moderate to heavy mountain snow, and high winds to the Northwest. Strong Santa Ana winds and very dry conditions are producing elevated to critical fire weather conditions in southern California. Isolated strong to severe thunderstorms are possible through early Wednesday morning across parts of northeast Texas into western Tennessee. Read More >

Overview

A fast moving storm system began moving through the region during the afternoon of Wednesday, January 18th. Snowfall intensified during the evening and overnight hours, and ended during the morning of Thursday, January 19th.

As heavy snow developed Wednesday evening, snowfall rates of 1-2 inches per hour were recorded. Northeast winds gusting up to 30 mph resulted in areas of blowing and drifting snow, leading to poor travel conditions across the Tri-State region.

In the wake of the storm system, a band of snow ranging from 8 to 12 inches was observed across portions of northern Nebraska, southeast South Dakota, and northwest Iowa. New daily records were set for both precipitation and snowfall in Sioux City. A sharp snowfall gradient was reported farther north.
