Even after a week of snow, tomorrow may be our only snow-free day for a while as a quick moving wave passes over the Steamboat Springs area Sunday and veers our flow from the southwest to the west and northwest. Snow should start falling during Sunday morning and periods of light to moderate snow should continue overnight and through Monday as additional weak waves Sunday night and Monday pass over the area. The timing of these waves in generally moist west to northwest flow is difficult and differs between the models, but I would expect around 4-8” of snow by Monday morning.
After a brief break and 2-5” for the Tuesday morning report, the snow machine cranks up again starting early Tuesday as a wet Pacific jet stream takes aim on Colorado and brings snow and windy conditions, especially to the higher elevations. Periods of moderate to heavy snow are forecast during the day Tuesday and overnight, leaving around a foot or more of fresh for the Wednesday morning report.
Snowfall should taper off, but likely not end on Wednesday and Thursday before a major storm is forecast to cross the West Coast early on Christmas Day. There are indications of a split storm which adds additional uncertainty to the forecast, but snow may increase over the Steamboat Springs area as waves eject from the storm located to our southwest as early as Christmas afternoon. This storm may be a slow-mover, though forecast details are sure to change with so much happening between now and then.
