Snowfall Totals | Reporting Snowfall
A major snowstorm crippled much of Wyoming from April 3-5, 2023. The combination of significant to record snowfall and strong winds led to blizzard conditions across eastern Sweetwater County, Natrona County, and Johnson County. The official snowfall total for Casper was 37.4" and is now the all-time record snowfall for one single event. Wind gusts of 30 to 50 mph created blizzard conditions and very large snow drifts. In Casper drifts as high as 8 feet were reported. On Casper mountain 5' of snow was reported and this snow buried many structures on the mountain.

The area from Rock Springs to Rawlins received much more snow than depicted on the image above. There were no reports in that area, which is why the map shows such low snowfall amounts, but there was at least a foot of total snowfall accumulation in eastern Sweetwater County.
