A strong and developing low pressure system lifted northeast out of the Plains and tracked across northwest Ohio and eventually into upstate New York. Cold arctic air, drawn from the north, clashed with warm moist air from the Gulf to create a favorable setup for all types of winter precipitation across Southeast Michigan. An ice storm ensued from I-69 south to I-94. Widespread ice accumulations of a quarter to a half inch brought down numerous trees, power poles and power lines. Over 150,000 customers were without power at one time during the ice storm. Many were without power for 2 days, and some for over 3 days. Several senior homes lost power and 200 residents had to be evacuated from one of them. Most of the damage and associated power outages occurred between M59 and I94. Although roads were just warm enough to remain mainly wet, patchy slick spots and downed tree debris made traveling very hazardous. Along and just north of the I-69 corridor, a mixture of freezing rain, sleet, and snow fell, where reports confirmed up to 5 inches of snow and one tenth of an inch of ice. Mostly all snow fell across the Tri-Cities and Thumb, where 4 to 6 inches of snow accumulated across portions of these areas. Although many schools were already closed to observe Martin Luther King Jr Day, nearly all of the other schools in Southeast Michigan closed on Monday due to the storm, with the exception of Monroe county schools, where precipitation fell as mostly rain. Over 50 Detroit metro area schools remained closed on Tuesday due to power outages. Numerous car accidents occurred across the affected areas. Several vehicles were destroyed by large trees that fell under the extra weight of the ice and there were at least two incidents of trees falling onto moving vehicles. Most injuries (all indirect) were minor. Total property damage was roughly estimated in excess of $2M. This included damage to vehicles, homes, businesses, and electrical poles and transformers. Downed power lines also sparked several garage fires. In addition, many businesses in the hardest hit areas reported losses due to the extended power outages.
