A storm system moving through the Rockies will move east and spread snow into the Plains during the day on Tuesday.
Although the heaviest snow is forecast to fall over the mountains, accumulations may still lead to some travel delays in the lower elevations from Colorado to Montana and into Iowa through Tuesday.
This includes the cities of Billings and Missoula, Mont.; Cheyenne and Casper, Wyo.; Rapid City, S.D., Denver, Colo.; and Omaha, Neb.
While snow may begin to accumulate on elevated and grassy surfaces shortly after the onset, it will take longer to stick on roadways due to the recent record warmth.
However, once the snow does start to accumulate on roads it can lead to slick conditions, slowing traffic and causing longer commutes.
Not only will this snow raise the risk of travel delays, but also avalanches.
The snowpack in the mountains has undergone weakening over the past several days due to the recent snow and milder weather. Additional weight on this snow can trigger avalanches in the northern Rockies.
Snow will taper off on Tuesday night as the system tracks eastward, bringing the threat of snow to the Northeast for Wednesday.
