Snow showers have developed overnight and have been most numerous north I-80 in the Wasatch and Bear River Range. Not much accumulation, but some areas like Beaver reporting a couple of inches of snow and a few others reporting an inch. These snow showers should clear out this morning as the initial wave moves out. Today should be mostly cloudy and windy ahead of the main system which arrives late this evening and overnight. 

Snow will develop tonight. Latest HRRR shows the heavy stuff beginning in the central Wasatch around 11pm. This is associated with the initial front which will drop good snowfall amounts tonight into tomorrow morning. You can see the NBM total liquid through 9am tomorrow when lifts open:

In general, probably 6-12" by the time lifts open tomorrow for northern Utah resorts. The snow will continue tomorrow, but we may see a bit of a break as the initial front moves out. Then, a more unstable northwest flow will develop later in the day and carry us through Tuesday. I gotta say though, the latest GFS doesn't show much of a break with the snow just continuing to pile up in Upper LCC:

Notice 3.5" of liquid... and that equates to a lot of snow! Is it possible? Well, the models are very consistent showing a long period of very good NW flow late Monday through all of Tuesday. Plenty of moisture, instability and great orientation. Orographic events are always a wildcard, but this one looks pretty likely. So yes, I think it's possible in LCC which is favored in this storm. 

You can see the total liquid through Wednesday AM is quite impressive in the NBM:

And the GEFS plumes:

Essentially, every where I look there is support for big snowfall amounts. Liquid amounts are generally 1.5-2.5" for most of northern Utah mountains through Wednesday AM. With average ratios of 15:1, that would mean 23-38" of snow. For the Cottonwoods (LCC in particular), liquid amounts are generally 2.5-3.5" which would mean 38-53" of snow. It's possible that we even see higher average ratios with plenty of cold air. Just look at these 700mb temps for Tuesday:

-14C would be cold for January, but it's very cold for early April. This snow is going to be fluff! 

OK... so we know we have a big storm. The riding should be great at most areas Monday, Tuesday, and Wednesday. What about logistics? The last storm closed LCC for a day and BCC was even closed for a long period. Well, anytime you get 30-50+" of snow in 48 hours, you're going to have issues. But when you consider how much snow we already have and how little time most of it has had to settle this season, I think it's very likely to cause headaches again. I would say it is VERY likely that LCC in particular will close for periods of Monday and Tuesday and there's a decent chance LCC won't be able to open at all on Tuesday. I can't say that for sure, but we are reaching critical mass on snowfall right now and keeping people safe is priority #1. Be aware and have a backup plan. 

If you're ready for a break, I have good news for you! Later this week we should dry out and right now it looks like at least a week of dry weather and warming temperatures. That would carry us from April 6 to at least April 13. After that, we could see a chance for some storms to return but it's too far out to know anything for sure. Enjoy it! Hopefully, we will see some of the low and mid elevations shed their snowpack a bit to help alleviate flood concerns.
