Another Weekend Refresh

Posted Saturday, March 13th, 2021 by Brittany Whitlam

TL;DR: Unsettled weather will continue through midweek as a few systems pass through our region. 

Nowcast: Scattered snow showers have brought some fresh flakes to portions of the Wasatch today. LCC received 8” of fresh snow since the lifts stopped spinning last night, while BCC received 7”. Southern Utah resorts didn’t miss out on the action either, with Brian Head reporting 5” in the past 24 hours. On-and-off showers will continue through the remainder of the day as the closed low currently settled over south central Utah shifts east overnight.

Short term: The upper level low that is currently making its way through southern Utah will continue to produce light snow showers over the northern Wasatch overnight. Northeasterly flow will prevail following the system’s passage over the Four Corners region tonight, favoring greater snow accumulations along the Park City ridgeline and upper BCC. Expect any remaining snow showers to taper off through the early morning hours tomorrow. An additional 2-5” are expected in the Cottonwoods through the end of this storm cycle.

Conditions will briefly dry out tomorrow through Monday morning ahead of another upper level low passage on Monday night. This system is expected to produce some more mountain snow, starting late Monday night and continuing through the day on Tuesday. Models are currently showing a spread of 3-8” for the storm total in the Cottonwoods. Confidence is not very high, so these numbers may need tweaked in the next few days as the models evolve. 

Time-height at Alta nicely sums up this week’s weather: Northeast flow and a good amount of moisture will favor the PC Ridgeline and BCC tonight. Brief dry-out Sunday night through Monday afternoon before another upper level low passes through on Tuesday.

Long term: Ridging will fill into the western US on Wednesday and persist through the end of the forecast period. Expect some nice spring skiing days during the latter half of next week.
