A powerful April snowstorm buried parts of Colorado under feet of snow, forcing road closures and flight delays over the weekend.
The storm's slow movement allowed heavy, wet snow to persist for more than 24 hours in some locations.
The heaviest snow fell across the Colorado Rockies. Over 40 inches accumulated near Pinecliffe, Colorado, just southwest of Boulder. Amounts between 20 and 30 inches were widespread.
Portions of I-70 and I-80 were closed for a time due to white-out conditions.
The weather also snarled air travel for thousands, as snow forced the cancellation of nearly 70 percent of inbound and outbound flights at Denver International Airport on Saturday.
"April is typically a battleground between winter and spring, so it is not unusual for a major snowstorm to occur from the same system that is spawning severe weather a few hundred miles away," AccuWeather Meteorologist Renee Duff said.
"The clash of cold air to the north and warm air to the south played a big role in the intensification of this storm," Duff said.
A Saturday matchup between the Colorado Rapids and the New York Red Bulls in Commerce City, Colorado, went on despite the weather. However, crews spent the hours leading up to the game clearing the field with snowplows.
Despite best efforts to keep the field clear, the storm's heavy snowfall caused the start of the game to be delayed and halftime to be extended for plowing operations.
