Overview

A powerful storm system crossed the Rocky Mountains early during the week of December 11, 2022, then nearly stalled over the Great Plains. The result was an initial surge of warm air creating rain and even thunderstorms for Nebraska, then a switch to heavy snow starting in the panhandle. Northwest winds grew stronger throughout the event, creating several days worth of blizzard conditions to much of western and north central Nebraska. What set this storm apart from previous blizzards was the prolonged period of strong winds after the bulk of the snowfall ended. Impacts included several foot-high drifts of snow in the Sandhills and multi-day highway and interstate closures affecting the immediate area and beyond.
