Moisture continues to stream into the Western U.S. from the Pacific Ocean. An active Jet Stream is expected to continue through Thursday, keeping the moisture train going throughout much of the week. Another piece of energy in the Jet Stream will push into the coast tonight and will move eastward through the region into Wednesday. On Thursday, the final area of moisture and energy with this system will move ashore.
Blizzard Warnings continue throughout parts of the Sierra Mountains for heavy snow and strong winds gusting over 60 mph at times. 1 to 3 feet is likely, with the highest mountain peaks seeing nearly 5 feet of additional snow.
The Southern Cascades and the mountain ranges across Idaho are under Winter Storm Warnings. 1 to 2 feet of snow is possible in these areas through Thursday.
The Wasatch Range and the Rockies will also see significant snow. Winter Storm Warnings continue for these areas as well.
1 to 3 feet of snow is possible in the Tetons, with lighter snows into the Black Hills.
A cold front will continue to push eastward through California tonight into tomorrow. Heavy snow will spread from the Sierra into the Rockies. Another low will move into California on Thursday, with another round of snow. Once that low pushes to the east and out of the region, the West will see a break from the precipitation.
