March Showers

Posted Thursday, March 15th, 2018 by Trey Alvey

Some pretty impressive numbers in terms of the liquid water equivalent (SWE) from this storm – 1.8 inches of water at Alta but only 12 inches of snow. This is an average ratio around 7:1 (snowfall:water)…think Sierra Cement. I wasn’t able to sample the goods personally, but I bet it’s actually skiing quite well being right-side up. The high amount of water also means that any crust underneath should be totally covered.

Short Term

Additional light accumulations this evening/overnight should help keep the snow fresh for tomorrow morning, but I wouldn’t expect too much more (1-3 inches). Snow showers should clear out overnight giving way to slightly warmer and drier conditions by tomorrow.

The next storm should begin moving across our area by Saturday afternoon. The GFS has been trending more towards a splitting system with the brunt of the precipitation to the north and south of Northern Utah. The European does show slightly more precipitation, but for right now I’ll take a stab and go with 3-6 inches Saturday afternoon to Sunday morning. Hopefully the models will shift just a tad, and these totals will be upped a little in tomorrow’s forecast. Regardless, the skiing should be good, and a nice change of pace from the Spring skiing we had earlier this week.

Long Term

Conditions should clear out as temperatures gradually warm early next week. The next potential storm appears to be mid-late next week, though models have been struggling with the timing.
