A band of snow is traveling northeast over Colorado Springs, expected to continue into late Wednesday afternoon, according to the National Weather Service.
Paul Wolyn, NWS meteorologist, said Colorado Springs is expected to get between one and four inches of snowfall, but most of it will melt. Northwest Colorado Springs may see some accumulation, Wolyn said, but it will be in grassy areas.
Northern El Paso County, especially in and around Monument, could see between three and six inches of snowfall.
Wolyn said roads will be wet from melted snow and with the temperatures dipping into the low 20s tonight, roads could become icy.
The record low for this day was 21 degrees in 1954, Wolyn said. The coldest temperature on record for May in Colorado Springs was 15 degrees, in 1916.
Denver International Airport is reporting a total of 46 flight cancellations, according to Laura Cole, DIA public information officer. These are mostly smaller commuter planes.
Cole said there are no significant delays, but they are possible as the day's snowfalls continues. All runways are open.
The May Day snow storm was making travel difficult on Interstate 70 in Colorado's mountains and along Interstate 80 in southeastern Wyoming, according to the Associated Press.
Nearly 3 feet of snow is possible in the foothills and mountains of northern Colorado while around a foot is expected at lower elevations in parts of both states. By midday, over a foot fell at Rocky Mountain National Park. The heavy snow caused power and heat outages there and in Cheyenne.
Parts of the Midwest were also getting rare May snow.
South Dakota's largest city, Sioux Falls, got its first May snowfall in 37 years. A winter storm warning was also in effect for parts of Minnesota and Wisconsin.
The storm is welcome in Colorado and Wyoming because it boosts the snowpack that provides the region's water supply. Both states are in a drought but have benefited from several rounds of spring snow. However, the recent storms have largely missed southwestern Colorado, which remains dry and at risk for wildfires.
