Heavy snow impacted much of Western and Central Wyoming beginning Sunday night. The heaviest snowfall fell east of the Divide first around Cody early Monday morning, with snow spreading to the rest of the area by Monday evening. This really was a storm for Casper as all the ingredients came together for them the longest with heavy snow falling from late Monday afternoon through Tuesday morning where snowfall rates exceeded an inch per hour for much of that timeframe. Light snow continued to fall across the Casper are through Tuesday evening.
