A few severe storms are possible across parts of lower Michigan tonight, primarily between 9 PM – 3 AM. The main hazards from any strong storms will be damaging winds and large hail. Read More >

Overview

A strong low pressure system trekking across southern Canada interacted with a weaker secondary low lifting through northern Michigan on January 7. Abundant moisture was in place as this system moved through to allow for an impressive amount of precipitation across the region. On the north side of the low, eastern Upper Michigan received a swath of heavy snow that exceeded a foot in many areas. Strong winds gusting 40 to 50 mph at times also created localized blizzard conditions across portions of eastern Upper, with whiteout conditions and blowing and drifting snow. Somewhat warmer air over northern Lower Michigan supported a messy wintry mix of snow, sleet, freezing rain, and rain which led to sloppy slush-covered roads in many areas.

Precipitation lifted into northern Michigan during the evening hours of January 6, overspreading the entire area by the following morning. Heavy snow continued across eastern Upper through the day on the 7th, while the wintry mix over northern Lower transitioned to a period of freezing rain in many areas, resulting in around a tenth of an inch of ice accumulation. Gusty southeast winds, combined with the icing and heavy, wet snowfall, led to isolated power outages across eastern Upper and northern Lower Michigan during the day. Precipitation tapered off and winds diminished by late evening.
