Another blizzard became the main weather event of the nation on Sunday, as a potent winter storm lifted northeastward across the Central Plains.

A wide swath of snow developed to the north and west of this system, blanketing areas from the Northern Plains into the Upper Mississippi Valley this afternoon with impressive reported snow accumulations of up to 10.5 inches.

In addition to snow, strong winds of 30 to 40 mph and gusts to 50 mph and higher swept across the region and led to lowered visibilities to whiteout conditions, periods of blowing and drifting snow, and dangerous travel conditions. Blizzard Warnings continued for areas of central Nebraska and the Northern Plains into the western Minnesota through the afternoon and into the evening hours.

Meanwhile, ahead of this system, warm and moist air from the Gulf of Mexico streamed northward across the Central Gulf Coast and set the stage for unsettled weather conditions from the Central Gulf Coast through the Upper Great Lakes this afternoon.

In the North, sufficient moisture and cold temperatures allowed for a mixture of precipitation with areas of rain, freezing rain, sleet, and snow to develop across parts of Wisconsin and Michigan. To the south, rain and thunderstorms developed from the western Ohio Valleys through the Tennessee Valley and the Central Gulf Coast States.

Areas from Louisiana into Alabama were at slight risk of severe thunderstorm development as strong thunderstorms in the region became more organized. The main concern with severe weather development for this area were damaging wind gusts and a few tornadoes.
