1991 Halloween Blizzard - Precipitation

Precipitation

The precipitation from this system began falling as snow in Iowa late on October 30, and by the morning of October 31 it had changed over to ice and spread northward across southeast Minnesota. During Halloween day the precipitation spread to the north where it fell mostly as rapidly accumulating snow. The snow continued to develop northward, eventually spreading into the Minnesota Arrowhead. Eventually all of the precipitation changed over to snow, and in some areas it would continue falling until November 3.
