There were 3” of snow at 8 am on my deck this morning, and snow has picked up early this Sunday afternoon in Steamboat Springs with almost 5” there now. Snows should let up for a time tonight, but pick up again Monday before decreasing and migrating to the higher elevations on Tuesday. After a short break in town on Tuesday, another storm rolls in for Wednesday with more significant snowfall before this bout of winter-like weather ends as we finish out the workweek and head into the weekend.
Unfortunately the Steamboat Ski Area has not enabled their powdercam yet for the season, but the Tower SNOTEL atop Buffalo Pass at 10,500′ just north of town estimated at least 15” of snow as of noon with about half that indicated at the Rabbit Ears SNOTEL at 9400′. Snow showers will continue this afternoon before diminishing or ending for a time overnight, especially at the lower elevations. But a trailing surge of cool air will restart the snows again on Monday, so we could see another 2-4” in town by Monday night and 5-10” at the higher elevations.
While snows should end for Tuesday in town, they will continue at the higher elevations, albeit with much lighter intensity.
A secondary push of moisture, energy and cold air is forecast to cross northern Colorado early Wednesday. As temperatures cool aloft, snows will begin again overnight, especially at the higher elevations in our most favorable northwest flow. But town will not be left out and I would expect periods of moderate to heavy snow showers at all elevations during the day Wednesday before they taper off around midnight and end by Thursday morning. Significant accumulation and difficult travel conditions are again expected if the storm evolves as currently forecast, with storm totals from Tuesday night through Wednesday night in the 3-6” range in town and 6-12” range at higher elevations.
After a chilly start to Thursday with temperatures well below our 25 F average, clouds should give way to some sun, especially in the valley, as temperatures warm, though high temperatures will still stay well below our average of 57 F.
Another chilly Friday morning will yield warmer and sunnier weather that looks to persist for Saturday as a ridge of high pressure temporarily moves over the West. But the break in winter-like weather may be short-lived as a strong storm brews in the Gulf of Alaska by the end of the workweek. The storm is forecast to move eastward and mix with some very cold air from the Yukon and Northwest Territories of Canada as it makes landfall around Vancouver on Saturday. Weather forecast models agree that the storm will split soon after making landfall, so there is quite a bit of uncertainty with the weather forecast for the end of the weekend and early the following workweek.
