The Major Snowfall of April 16-17 2023

Overview

A major weather system moved through the area late in the weekend and into Monday morning after record breaking warmth the week prior. Temperatures were in the 80s Tuesday through Thursday but plummeted into Sunday, with rain changing to snow in the afternoon.

Western into central Wisconsin was hit the hardest with over a foot of very wet heavy snow along a north-south band. Some saw snow amounts near 20". Tree damage, some power outages, and numerous auto accidents impacted the area.
