WET WEEK AHEAD FOR THE CASCADES AND NORTHERN ROCKIES
Powder alerts continuing for the Sierra tonight as a final round of snow is just moving out before dumping another 4-7 inches above 7,000 feet this evening. Some spots of the Sierra have seen over 5 feet of snow this week!
The Wasatch will see the benefits of the final round of precipitation late tonight through Monday AM with slightly lower snow levels (5,000-6,000 feet). NOAA is forecasting up to a foot in Northern Utah south of Interstate 80 however models show better energy to our south (Provo into the central mountains). Therefore, I am going with another 3-6 tonight and 2-4 tomorrow morning. Resorts such as Snowbird and Alta stand the best chance of decent snowfall with NW flow. The path is taking a southerly aim towards Sundance so we cant rule them out as a wildcard. Colorado is seeing energy this evening quickly diminish with heavy snow showers over Aspen and Vail Pass. Energy will increase by 10AM on Monday and continue through the day (Aspen, Vail, Powderhorn, Beaver Creek, Steamboat favored). Storm skiing might get you in the 7-8 inch range by 3PM.
The extended forecast looks very moist and unfortunately warm! Snow levels in the south Cascades will rise as high as 7,000 feet early this week. Light snow Monday will turn moderate by Tuesday afternoon and heavy over the north Cascades (Baker). Snow levels will drop up north (4,000 feet) but remain high in the south. Wednesday could see some deepness? Energy continues into the week with several disturbances crashing into the Northwest. The northern Rockies (Idaho, Wyoming, and Utah) will see the brunt of action beginning late Wednesday or early Thursday. Very moist and warm systems will increase Avalanche danger significantly by the end of the week. Resorts in Wyoming might stand the best chances of deep dumps followed by the high elevation areas of the Wasatch. This pattern continues for most of next week. Colder systems are showing up in the extended forecast for the following week!
