Just a quick update from the below POWDER ALERT, as the northern Sierra is getting pounded again tonight with an additional 9-14 inches on top of the 12 recorded this afternoon at Squaw Valley. Web cameras and snowtel sites are all confirming heavy snow currently piling up over Interstate 80 near Truckee. Rain and snow is falling moderately over the Northern Wasatch under SW flow impacting areas North of I-80 such as Powder, Snowbasin and into the Tetons of Wyoming (Rain at base and snow up high). Sun Valley even saw some snow during the day on Monday according to our trustworthy spotters up there who posted on “powder buzz”
Tuesday will usher in colder air for the Rockies so rain in Jackson might turn over to snow by 6PM and light to moderate snow will continue in Utah especially above 7,000 feet. On Wednesday even colder air will bring a higher chance of powder to the mountains in the Southern Wasatch such as Snowbird and Alta with the winds shifting to the Northwest. The totals there for the week should be in the 11-15 inch range. Snowbasin and Powder Mountain might end up with 12-18 at the highest peaks!
The Colorado Mountains will see some snow above 9,000 feet North of I-70 Tuesday night into Wednesday however the best chance of Statewide snow especially over the Vail Valley and North will be on Thursday/Friday (3-7 inches likely).
Here is a pic from Squaw Valley USA as of this afternoon.
