Snowbasin just hit an all-time record today with 482 inches YTD. They hit this in style and on a sneak-up powder day where the 5 AM report was 3 inches and by opening at 9 AM they had 12 inches. Full on powder day with 2 inches per hour until opening for those lucky ones that grabbed it. This was not in anyone's forecast! 

Below: @bob.e.gnarley via Instagram sent me this photo from Snowbasin on Sunday. He nabbed fresh powder this morning as they surpassed the all-time record seasonal snowfall. 

This forecast is what I call OpenSnow Light as I am posting Sunday evening in anticipation of chasing powder Monday. I will get to the point quickly. 

The models show a 60/40 chance of some decent totals in the Wasatch for Monday morning. Most of the snow on Sunday fell in the Logan (Beaver) and Ogden area mountains and extended to the western side of Park City (Less at the resort than on Parleys Summit or Jeremy Ranch).

The models for Sunday night show enhanced snow showers setting up anywhere from Ogden (Snowbasin, Powder) to the central Wasatch (BCC, LCC). It's possible that 5-10 inches get reported with no real agreement on exactly where these bands will set up. While I have confidence in a decent Sneak up Monday I would not be surprised if resorts also came in with much less. Keep an eye on the webcams Sunday night and the morning snow reports. There is a huge spread in totals with the American GFS at 10-15 inches for Alta while the short-term models (HRR) show 3-5. I honestly have no idea what is going to happen. 

The best chases of the week will be contained to Northern California resorts on Tuesday (Mt Shasta) and a good portion of Oregon. Tuesday will see deepish storm skiing with the highest totals at Shasta. On Tuesday late AM to Wednesday morning, the Tahoe Basin scores double digits with Mammoth catching up late Tuesday to Wednesday (Deeper totals). Last chair Tuesday or 1st chair Wednesday could be your best bets with decent quality pow. Mammoth might be the deepest resort for overnight pow for Wednesday. 

Below: Total snowfall for the Sierra looks decent from Tuesday to Wednesday. Moderate snow or some isolated heavier totals are also noted in Oregon. Ride Tuesday or Wednesday (North to south). 

Below: Strong cold front for the Sierra moving through Tuesday PM to Wednesday. 

The system over the Sierra moves south and east bringing some decent totals to the southern mountains in Utah extending moderate snow to the Wasatch Range Wednesday and Thursday as well as the Tetons. The models are also hinting at heavy snow for the Sawtooth Range extending south into Sun Valley for Wednesday/Thursday (GFS is very bullish). 

This system does not look to be a blockbuster 12-hour dump but could bring some decent totals over the 48-hour midweek period (9-15) for the Wasatch. 

Colorado starts to see snow on Thursday which favors the western areas near Aspen and south to Telluride. While moisture streams to the south, this is one of those storms where I am more bullish for Telluride than Purgatory or Wolf Creek. NW flow on the back side of the low will pump ample moisture into Telluride late Thursday or early Friday. The I-70 corridor might fire on Friday but amounts are likely going to be less (Could still be decent). Perhaps storm ride over southern areas Thursday and move north on Friday (Telluride or the I-70 corridor). Highlands and Snowmass can sometimes do well with NW flow also. 

Below: 7-day snow totals (Low confidence this far out) with plenty of chases. The Sierra, Oregon, Southcentral Idaho, and southern areas on this map score Tuesday-Thursday while the highlights in the PNW and Canada happen by the upcoming weekend.  Temps stay cold! 

The weekend brings another system into the west favoring the PNW (Washington gets back into the game). That system looks to favor the Northern Rockies (ID, WY, MT, UT, CO).  Things stay active in the first week of April with additional storms likely.

Enjoy the powder, everyone!
