One-Off Sleeper Day

Posted Tuesday, April 6th, 2021 by Nathan Tarino

TL;DR: An upper low tracking across the UT/ID border brought heavy snow to the Wasatch overnight. Skiing conditions should hold strong through tomorrow morning, before the hot April sun begins to affect the new snow. There isn’t a ton of snow coming, so maybe get after it while you can.

Nowcast: As of about noon Tuesday, our storm has deposited 7-8″ of new snow in BCC, 9-12″ in LCC, and ~5″ across the Park City resorts. Mountain temperatures are low, in the teens and 20s. This should keep the snow nice while the clouds stick around today.

With the upper low now off to our east, northwest flow behind the low is supporting continued snow showers.

NW flow behind the trough is keeping the threat of snow showers around, tapering by the mid afternoon.

Short Term Forecast: Snow will end soon as the airmass impeding on the Wasatch dries out, and we will transition back to clear skies by tonight. This leaves a short window for good snow quality – if you want to ski pow again this season I’d recommend a dawn patrol tomorrow. The caustic April sun will do some damage to the snow by lunchtime tomorrow on all but the shadiest slopes.

As for snow chances in the mid and long range, there isn’t a ton to discuss. A trough will graze us from the north Thursday evening, possibly supporting a snow shower or two, but don’t expect any accumulations. Another trough is expected to miss us to the north again this Sunday. At this point I’m hoping to see guidance trend farther south with this feature, as the going solution won’t bring any real snow.

I hope we get at least one more April dump, but the forecast looks a touch bleak. You’d better go skiing tomorrow morning.
