Blizzard conditions to sweep across US Rockies into Wednesday

Colder air will continue to plunge across the western United States and set the stage for heavy snow and blizzard conditions through early Wednesday.

"A developing storm across the western Plains and approaching cold air from Canada will set the stage for accumulating snow across the Intermountain West and blizzard conditions across eastern Wyoming," AccuWeather Meteorologist Brett Rossio said.

Heavy snow and strong winds will produce blizzard conditions across much of eastern Wyoming and extreme western Nebraska during Tuesday night and early on Wednesday. This includes the cities of Buffalo, Casper and Cheyenne, Wyoming, and Scottsbluff, Nebraska. Snow totals in these areas could approach or exceed a foot.

"Wind gusts could approach 50 mph at times," Rossio said.

The strong winds will contribute to blowing and drifting snow.

"Visibility will be near zero along portions of interstates 25, 80 and 90 due to the combination of snow and blowing snow," AccuWeather Meteorologist Michael Doll said. "This could lead to road closures for several hours during Tuesday night and Wednesday morning."

Accumulating snow will also spread across portions of Nevada, Utah, Colorado, Montana and South Dakota. The worst of the storm will miss eastern Colorado, including Denver, which has already received nearly two times the normal snowfall for March.

Anyone heading outdoors will want to bundle up as highs on Wednesday will run 10 to 25 degrees Fahrenheit below normal. Late-March normal highs range from the low 50s in Cheyenne, Wyoming, to the upper 50s in Denver. The addition of strong winds will make it feel like the dead of winter rather than early spring.

The storm will push eastward on Wednesday and raise the threat for severe thunderstorms and flooding rainfall to the Central states. Conditions will improve across the Rockies throughout the day.

There remains the potential for additional storms to bring accumulating snow to the Rockies, especially in the higher elevations, during the second week of April.

Any snow will be beneficial to ski resorts, some of which are planning to remain open into early April.
