The flavor of spring that Minnesota had for the past few days will be wiped out by a quick snow spurt on late Saturday night and late Sunday morning, and the totals can be quite impressive where a narrow band of heavy precipitation forms.
According to the National Weather Service, there may be a narrow corridor that ends with 5-7 inches of snow. That’s where a winter storm watch has been issued in southwestern Minnesota, while a winter weather advisory has been drafted further east and north, including the Twin Cities, where 2-4 inches of snow can accumulate.
