Multiple Cold Weather Advisories are in effect across Michigan through Thursday morning, with wind chills dropping to 10 to 20 degrees below zero in many areas. Luce County faces particularly brutal conditions with air temperatures dropping to around 10 degrees below zero and wind chills near 20 below zero through Thursday morning. Lake effect snow showers continue to impact western Lower Michigan along the Lake Michigan shoreline, with Winter Weather Advisories in effect through Thursday morning for counties through the Grand Rapids area. Another round of more intense lake effect snow may develop Friday evening into Saturday morning across northwest Indiana and southwest Michigan as a sharp Arctic trough pushes through the Great Lakes region. High pressure will bring some improvement this weekend with diminishing lake effect snow, though temperatures will remain well below normal with highs only in the teens to low 20s.
