The trajectory of a spring snowstorm headed for Minnesota shifted overnight, leaving the Twin Cities free and clear. Southern Minnesota, however, could still see blizzard conditions.

"In addition to the heavy snow, northerly winds of 30 to 40 mph will develop causing blowing and drifting snow. In south central Minnesota, wind gusts could exceed 45 mph, which could lead to whiteout conditions," the NWS added in the warning.

A spring storm is forecast to bring blizzard conditions to a swath of southern Minnesota on Wednesday — and ahead of that, some school districts are canceling classes or moving to online learning.
