The snow has started on New Years Day 2020 in Steamboat Springs as snowfall rates as high as an inch per hour were observed mid-morning. The storm looks to deliver as promised, or even over-achieve, with 8-16” of light and fluffy powder expected by the Thursday morning mid-mountain ski report and an additional 3-6” by Friday morning, leaving a storm total of almost one to two feet. While the snowfall from this storm will end on Friday, with even some sun possible for Saturday morning, cool and unsettled weather with at least light snow showers will be over our area from later Saturday though Tuesday morning. A bit of a break is advertised from later Tuesday into Wednesday ahead of our next possible storm for later in the work week.
Three inches are shown on the powdercam as of 10:30 am this Wednesday, and though the snowfall has currently waned, it should pick up again later this morning for several hours. And after another decrease in intensity for the early afternoon, moderate to heavy snow showers should occur late in the afternoon and continue through most of the night. Snowfall rates of one to two inches per hour along with some wind will make travel quite difficult at times, especially at pass level, but even in town.
Though the heaviest snowfall will be over by around report time on Thursday morning, an additional 3-6” of light and fluffy powder is expected by the Friday morning report as showers continue, with shower intensity greatest from mid-afternoon through mid-evening on Thursday, and daytime temperatures hovering around 5 F at the top of Mt. Werner.
Light snow showers are forecast to hang on through Friday morning, with minimal additional accumulations expected.
Dry air briefly works into our area on Saturday, with at least some sun in the morning, as a ridge of high pressure traverses the Rocky Mountains. But waves of Pacific energy and moisture in generally favorable northwest flow will restart light snow showers as early as Saturday night. We may see some sun again on Sunday morning, but showers are expected from later Sunday through Tuesday morning.
As is often the case in fast and energetic flow off the Pacific, the timing, track and strength of waves of energy and moisture are difficult to forecast too far in advance, and weather forecast model disagreement emerges by later Sunday as the European ECMWF is more optimistic with a storm around then. My next weather narrative on Sunday should offer some clarity on the the eventual strength of this storm.
In any case, there is agreement that the snows will stop for most of Tuesday and Wednesday before a healthy but quick-moving storm is advertised for around the end of the work week, followed by a longer lasting storm around the weekend that may persist into the following work week.
