Something to cover up the rain crust

Posted Friday, March 23rd, 2018 by Peter Veals

It rained a lot yesterday and last night, and it did it up to 9,500ft in most areas. Rainfall totals in the Cottonwoods and the southern Wasatch were generally the 2-3″ range, with closer to 1″ in the northern Wasatch. Things cooled off a bit last night and snow levels dropped to around 7,000ft this morning, with most areas picking up a few inches of dense snow before the precip shut down by late morning. Areas above 9,500ft got slammed with large amounts of very high density snow, but everywhere else, this storm was a disaster.

Fortunately, the forecast for this weekend and early next week does have some snow for the Wasatch, and maybe even down to the valley floors. The amounts are not super promising, but they’ll hopefully be enough to cover up the rain crust a little bit. It looks like a quick couple inches Saturday night, followed by a slightly stronger shortwave trough moving through on Sunday. For Sunday’s totals, I’ll go with 4-8″ at the moment. Sunday’s storm looks to be a cold one, with favorable cold northwesterly flow behind it into Monday, so that snowfall forecast may go up.

After that, we slowly dry out and warm up into the work week.
