Snow ongoing across western Minnesota will spread east Sunday morning, reaching the Twin Cities between 9 and 10 a.m. and western Wisconsin by early afternoon. Snowfall rates will briefly become heavy during the initial surge, reaching up to an inch an hour and reducing visibility, creating hazardous travel conditions.

Light to moderate snow will then continue through the afternoon and evening, with additional snowfall overnight into Monday morning as the storm slows to the east.

A blizzard warning is in effect for much of western, central and southern Minnesota, where the combination of snow and powerful winds will create the most dangerous conditions.

A winter storm warning remains in effect for east-central Minnesota, including much of the Twin Cities metro area and western Wisconsin, where heavier snowfall and periodic whiteout conditions are expected.

A winter weather advisory is in effect for areas just west and east of the blizzard warning, where snowfall totals will be lower but blowing snow could still create hazardous conditions.

Strong northwest winds will develop as the storm intensifies. Sustained winds of 30-35 mph, with gusts reaching 50-55 mph, are expected across western, central and southern Minnesota. These winds will cause widespread blowing and drifting snow, leading to near-zero visibility at times, especially in open areas.

Behind the cold front, temperatures will drop sharply, with many areas seeing a 20- to 30-degree drop. This rapid cooling could lead to a flash freeze in areas that saw rain earlier, quickly turning wet surfaces icy and creating hazardous travel conditions.
