A significant snowstorm roared across parts of the West and Plains today,while chances of severe weather activity heightened in the Great Plains.

A strong storm system over the Intermountain West shifted eastward as a strong cold front reached from the Central Plains across the Central and Southern Rockies and a strong low pressure system moved into Texas.

Heavy snow showers fell across areas of Colorado, Wyoming, western Nebraska, and South Dakota, while strong winds gusting in excess of 50 mph picked up across the region through the day. This combination of snow and wind translated into blizzard conditions in parts of eastern Colorado through the day with lowered visibility, high snow drifts, icy roads, and hazardous travel conditions.

Much of this wintry weather region and portions of southwestern Minnesota remained under Winter Storm Warnings and Winter Weather Advisories in anticipation of upcoming snow accumulations of 2 to 8 inches in the lower elevations and 15 to 20 inches in the higher elevation.

Blizzard Warnings continue for the mountains of Colorado through this evening. In addition to snow and wind, areas of morning freezing rain and sleet in Nebraska and parts of South Dakota led to possible ice accumulations of up to an inch.

Meanwhile, warm and moist air from the Gulf of Mexico streamed northward and supported more rain and thunderstorms from the Central Plains into the Ohio Valley and Great Lakes. This moisture tap continued the threat of severe weather development from the Southern Plains through the Mid-Mississippi Valley.

Areas from southwestern and central Texas northeastward through southern Iowa are at slight risk of severe thunderstorm development with large hail, damaging wind and at least a few tornadoes from the afternoon through overnight hours.
