Mammoth Mountain Ski area has recieved over five feet this week and should easily double that by Friday. The central and northern Sierra have recorded in the 18-24 inch range. Snowbird had 18 inches in just 16 hours yesterday where reports came in with epic conditions. Synopsis: The bulk of the storm will impact California tonight and tomorrow (two to three additional feet of snow likely) and slowly move into southern Colorado by Thursday afternoon. A swath of moisture over Nevada currently on radar should bless the Wasatch with another 8-11 inches late tonight and Thursday morning (bonus before the big one).
The heaviest snows from this event will be over the four corners area of the southwest cranking at full speed Thursday night into Friday morning. The amounts could approach 30-35 inches at Colorado's Wolf Creek and perhaps 18-22 inches at Crested Butte by noon Friday. Silverton Mountain is a given snow magnet in this pattern. Aspen should get moderate snow.
All areas of Utah/Idaho and Wyoming will pick up snow with a good chance of Park City, Snowbasin, and areas favored by southwest flow picking up 14-18 inches by Friday afternoon. The good news is that the winds are going to shift to the northwest on Saturday and Sunday which will keep a good chance of moderate snow in the Wasatch going through Saturday night. Finally, there is a very good chance of moderate to heavy snow finally for Vail, Steamboat and other areas of Colorado Saturday/Sunday (10 inches plus) with the wind shift form the northwest. The Tetons and areas in Central Idaho should see light to occasionaly moderate snow through the period. The chase picks of the week will be 1) Mammoth, 2) Deer Valley, 3) Alta, 4) Wolf Creek, 5) Crested Butte, 6) SIlverton. Wildcards? 1) Aspen, and perhaps Vail by Saturday night?
High pressure should build in for late in the weekend with another approaching storm likely on Tuesday. —Powderchaser Steve
