Snowfall totals from the March 22-23, 2011, Winter Storm

A low pressure system moved across southern Michigan overnight producing a wide range of precipitation types and amounts.  5-8 inches of snow fell across locations north of the I-69 corridor mixing with freezing rain during the morning hours for a while.  Though ice stuggled to form on most roadways, 0.1-0.3 of ice, was able to accumulate on trees and powerlines along I-69 causing about ten thousand of people to lose power in Shiawassee, Genesee, Lapeer, St. Clair, Macomb, and Oakland Counties.  The ice was in addition to 1-3 inches of snow and sleet that had fallen earlier in the night.  South of I-69, the precipitation changed rapidly from a sleet/freezing rain mix along the M-59 corridor to all rain from about I-696 southward.
