A major ice storm impacted much of southern Lower Michigan while areas of moderate to heavy snow impacted central Lower Michigan on February 22, 2023. Hundreds of thousands of customers lost power across southern portions of the state as freezing rain accumulated on trees and power lines, bringing branches, trees, and power lines down in many areas. In between the areas of freezing rain to the south and snow to the north, sleet (ice pellet) accumulation reached a couple of inches deep.

In order for freezing rain to occur, snowflakes that fall from the sky need to completely melt and not refreeze into ice pellets before reaching the ground. That was the case for most areas south of the I-96 corridor during this event. Along and slightly north of the I-96 corridor, ice pellets persisted for most of this event leading to 1"-2" of dense ice pellet accumulation. The environment stayed just cold enough above the surface to completely refreeze the melted snowflakes into sleet. Further north, the atmosphere was cold enough to keep precipitation all snow, where generally 2"-8" fell.

Wind gusts reached the 25-35 mph range for many locations during the height of the event. This added an additional challenge to areas that received heavy icing on trees and power lines.
