Another Alberta-Clipper moved across southern Minnesota on Thursday and dumped 2-4 inches of snow on the Rochester area.

The snow followed a period of freezing drizzle and created very slick conditions on roadways throughout the region. The Minnesota Department of Transportation continues to urge motorists to use extra caution because blowing and drifting snow has left travel conditions rated as difficult. Statewide, the State Patrol responded to over 230 traffic crashes and nearly 400 reports of vehicles off roadways. So far, there been no reports of serious injuries or deaths. One of the worst crashes occurred along I-35 just north of the Twin Cities where over a dozen cars and trucks either collided spun out on the freeway this morning. That area was under a winter storm warning, and some areas of the Twin Cities ended up with over 6 inches of snow.
