Cold is Coming

Posted Sunday, December 30th, 2018 by Lucas Bohne

It was a good day to stay at lower elevations or in the trees at resorts today as wind, snow showers, and low visibility conditions persisted up high. At Snowbird, the tram was closed for high winds all day and off-and-on snow showers intensified into some graupel this afternoon with no substantial accumulation. By about 4pm, the cold front and main precipitation band was moving through the Salt Lake Valley. Current webcams now show snow covered roads from the eastern benches of the Wasatch Front and eastward into the mountain regions, and Alta Collins has reported 4″ of snow so far this afternoon with 2″ of that in the last hour between 4pm and 5pm.

Snow Accumulations:

Snow will continue this evening with the heaviest accumulations in the mountains. It’s still reasonable to expect about 5-10″ for the Cottonwoods and Northern Wasatch resorts and 3-6″ for Park City resorts through midday Monday – not much of a change from yesterday’s forecast.

The Week Ahead:

Reiterating on Marcel’s post from last evening, the next several days are going to be frigid. The coldest air of the season so far will be infiltrating into the region behind today’s/tonight’s precipitation. New Year’s Eve and New Year’s Day are looking to be the coldest, with subzero lows in the mountains and highs only in the single digits to low teens. Valleys will have icy temperatures too, with lows in the single digits and highs only into the 20s for the first few days of the week. Higher elevations will experience some warming as the week progresses, but inversion conditions over the lower terrain will make it hard for the valleys to realize much warming this week. No good chance of snow is in the forecast for the work week, but there is potential for another active weather period beginning next weekend. Have a great and safe New Year’s Eve -it should be another excellent day in the Wasatch despite the cold!

Salt Lake City GFS Ensembles for the next several weeks. Current guidance suggests warming though the week at higher elevations, with potential for another active weather period next weekend. (wetterzentrale.de)
