I know what you're thinking. This was the storm that wasn't. But don't let down your guard or give up hope. Despite our skunking yesterday and last night, snow is still coming.
The analysis loop below shows what happened. The surface-based front made it to Salt Lake City yesterday around 3 PM and the accompanying surface trough has lingered just to our south. The precipitation, however, was less cooperative, providing a bit of snow for the northern Wasatch (1-3" according to the Utah Avalanche Center), but never really making it down to the central Wasatch or the Salt Lake Valley for reasons discussed in yesterday's post.
Currently, the surface trough appears to be draped across the southern Salt Lake Valley, but is a bit amorphous. Note the north winds near and around the airport and the south winds near and around Point of the Mountains.
The Salt Lake Valley will likely see a return of southerly flow today as the surface trough shifts a bit northward. More important, as the upper-level trough finally decides to swing eastward, the precip band gets its act together once again and like Lazarus rises from the dead. Note in the NAM forecast below how the precipitation fills in and the upper-level 700-mb trough intensifies over Nevada. As these features move eastward, we finally get some tonight and tomorrow, along with some post-frontal action late tomorrow and tomorrow night.
That NAM run puts down 0.75" of water and 13" of snow at Alta-Collins by 9 AM tomorrow and 0.94" of water and 16" of snow by 11 PM tomorrow night. For what it's worth, the SREF puts out 0.35 to 1.18 inches of water for the period. The Euro 0.6".
I know what you're thinking. You're not going to get suckered into this again. Fair enough. The past 24 hours haven't been pleasant for my profession. But I think you should be ready. Unlike Friday and Friday night, when there was great uncertainty in the position of the front and frontal precipitation, we can be confident that the front and trough are going to come through tonight and tomorrow, so the issue here is just how productive those features will be. In this case the odds favor a powder day tomorrow. I'll go for 7-14" at Alta by 9 AM tomorrow morning. And, while we're at it, some overnight snow for the valley's too. As always, monitor official forecasts and expect a cluster tomorrow at the bottom of the canyons.
