Another weekend (and spring break!) storm

Posted Friday, March 16th, 2018 by Mike Wessler

Sometimes it seems like the best way to get a big storm around here is for one of us to skip town… That certainly seems to be the case this weekend, with a handful of us taking advantage of spring break at the U to explore new places. For those sticking around, this storm should be a treat.

Snowfall will likely hold off until late Saturday morning, with the HRRR producing not much more than light snow showers overnight. For those that enjoy storm skiing, Saturday should get better as the day goes on. The main slug of moisture should come through in the early evening, with an intense period of precipitation that will likely be short-lived. Most models wrap up steady precipitation by Sunday morning around when resorts open. Snow showers are likely to continue on and off Sunday morning, ending in the afternoon.

Models have backed off on the amount of water associated with this system, and we are seeing a consensus around .8” of water for the central to northern Wasatch. With the predominant flow direction out of the SW, I don’t expect impressive enhancement over the Cottonwoods. Big, Little, and the Park City ridgeline should all see totals over 6 inches, with about half as much at the Park City base. Max of around 12” likely at the highest elevations at the head of the cottonwoods. Should some strong convection develop, lucky areas in a bullseye may see an inch or two more.

For those always thinking ahead, a few inches is possible into/through Monday.

Enjoy it for me!
