While the storm blasting California through Friday will weaken, locally heavy snow will push inland over the West this weekend, reaching Denver.
For most of the intermountain West, the storm will not pack intense winds it had for the Pacific coast, Sierra Nevada and Cascades. However, it will cause travel disruptions due to areas of heavy rain and lowering snow levels.
Following an initial surge of warmth, the storm will be a boost for some of the ski resorts in the region.
The storm will spread drenching rain with very high-elevation snow across Nevada, eastern Washington and Oregon and Idaho on Friday.
Enough rain could fall on parts of the Great Basin to cause flash and urban flooding. Motorists should be prepared for travel delays due to poor drainage area flooding from Las Vegas to Boise, Idaho.
During Friday night and Saturday, mountain rain and fog with desert showers will spread over Arizona, including in Phoenix and Flagstaff.
As colder air settles in Friday night, valley rain will turn to snow in some locations, such as in Elko, Nevada, and Salt Lake City.
A foot or more of snow is likely in the Wasatch Mountains Saturday into Saturday night. Similar snowfall will spread into the Colorado and Wyoming Rockies as the weekend progresses.
Travel over the passes along I-80 in Wyoming and I-70 in Colorado and eastern Utah may be difficult due to heavy snow, slippery roads, strong winds and poor visibility on Saturday night and Sunday. Motorists traveling cross-country may want to take a warmer, more southern route, such as I-40 through New Mexico and Arizona.
Depending on the track of the storm, Denver, Colorado Springs and Pueblo, Colorado, may receive several inches of snow during late Saturday night and Sunday. A track just south of these locations would bring the heaviest snow, while a track farther north would bring little to no snow accumulation.
AccuWeather.com will continue to provide updates on the Pacific storm as it pushes inland over the West through this weekend.
Following the storm and chilly trend this weekend, the pattern of mild Pacific air will resume, but with unsettled conditions at times for the West.
