Winter Storm of January 22-23, 2018

 

A classic "Colorado Low" snowstorm impacted the Upper Mississippi River Valley and upper Great Lakes from Monday, January 22nd through Tuesday,  January 23rd. The snow was exceptionally heavy and wet, with snow to water ratios averaging 7:1. The snow also mixed with freezing drizzle at times across the southeast half of Upper Michigan as well as the Keweenaw Peninsula. Due to the very dense nature of the snow, conditions were very slippery and travel was hazardous through the 22nd into the 23rd.
