Blustery storm today with next significant snow possible Tuesday
Thursday, February 18, 2016
Don’t let the current sunny skies fool you as this is a slot of dry air ahead of the very windy storm timed to cross the Steamboat Springs area late this afternoon. Gusty southwest winds will veer to the west and become stronger around and behind the frontal passage, with several hours of intense snowfall leading to blowing snow and difficult travel conditions around sunset.
Snowfall should be over by midnight, leaving 3-6” on the hill for the Friday morning ski report. Skies will become partly sunny on Friday before a weak wave to our north brings cooler temperatures and the threat of very light snow showers for early Saturday.
Drier air for Sunday promises a sunnier day before moisture increases late Monday ahead of a wave traveling over the West Coast ridge. This is an interesting development since some cold air from the Canadian Plains is forecast to mix with this wave, bringing some snows to the area on Tuesday.
The westward extent of the cold air over the Canadian Plains has been a key variable in our snowfall this winter. From about mid-December through early February, the West Coast ridge associated with El Nino events had been attacked from the west with Pacific energy and from the east by the cold air over the western Canadian Plains. We have done very well with snowfall as the moist Pacific air undercuts the ridge and overruns the cold Canadian air.
These last 10 days have seen the cold air move eastwards, bringing very cold air and winter weather to the East Coast, but leaving the West Coast ridge stronger and warmer, reducing the threat of snowfall for our area. I am hopeful that the cool air for the Tuesday storm marks a westward expansion of the cold Canadian Plains airmass and a return to a more active weather pattern.
Another drier and weaker wave is forecast to cross north of the area around Thursday, but current forecasts have no precipitation associated with this disturbance.
Current storm lasts till Tuesday morning followed by another Thursday afternoon

A moist northwest jet stream with embedded waves is over the Steamboat Springs area and is responsible for the 2” of snow that fell at the top of Sunshine Peak this afternoon. Continued gusty west to northwest winds up to 40 mph will continue the snow on the hill tonight as a wave moves across, leaving another 3-6” of snow for a 5-8” Monday morning ski report.
Snows will decrease in intensity but continue on Monday as the atmosphere warms slightly behind the departing wave, with an additional 1-4” during the rest of the day.
The last embedded wave moves across our area around Monday evening, cooling temperatures and increasing snowfall rates a bit, with an additional 2-4” overnight.
There may be lingering clouds and possible snow showers early Tuesday behind the wave, but the Great Basin ridge builds over us after that, bringing warm, dry air and sunny skies back over the area by later Tuesday into Wednesday.
A stronger storm over the Pacific is forecast to cross the California coast midweek and spread clouds over our area by Wednesday night and bring snows and moderate westerly winds to the area as soon as Thursday. There is uncertainty with regards to the amount of weakening the storm will undergo as it interacts with the Great Basin ridge, but current forecasts have precipitation peaking Thursday afternoon through midnight, leaving around 4-8” of snow by Friday morning.
Moderate storms bookend the following week

After a sunny Friday and Saturday, a wave in northwest flow brings some moisture and cool air over the Steamboat Springs area Sunday, beginning snows that will last through Monday night. Amounts are uncertain as models are wavering on the strength of this wave and its southern extent, but right now it looks like 3-6” may be reported on the Monday morning ski report, with an additional 1-4” during the rest of Monday.
There may be lingering clouds and possible snow showers early Tuesday behind the wave, but the Great Basin ridge builds over us after that, bringing warm, dry air and sunny skies back over the area by later Tuesday into Wednesday.
A stronger storm over the Pacific is forecast to cross the California coast midweek and spread clouds over our area by Wednesday night and bring snows to the area as soon as early Thursday. There is disagreement among the models as to the strength of this storm, but early forecast amounts by Friday morning are in the 6-12” range.
Chances for snow Sunday-Monday and at the end of the work week
Thursday, February 11, 2016
A shallow wave to our north and east will bring cloudier conditions for parts of today and tomorrow before sunny skies return for Saturday. Our next chance for snow is currently forecast to be from Sunday afternoon into Monday morning when a quick-moving wave in northwest flow brings some moisture and cool air over the Steamboat Springs area. Amounts are uncertain as models are wavering on the strength of this wave and its southern extent, but right now it looks like 4-8” may be reported on the Monday morning ski report.
There may be lingering clouds and possible snow showers on Tuesday behind the wave, but the Great Basin ridge builds over us after that, bringing warm dry air and sunny skies back over the area by midweek.
A moderate storm over the Pacific is forecast to cross the California coast midweek and spread clouds over our area by Wednesday night and possibly bringing snow showers to the area as soon as early Thursday. There is disagreement among the models as to the strength of this storm, with current forecasts bringing a possibly significant event across the area by the end of the work week.
Another storm tonight before mostly dry weather for the next week
Thursday, February 4, 2016
Another round of snows for the Steamboat Ski Area has begun with cloudy skies and light snow on the upper mountain as a wave in northwest flow moves over the area. Snows should increase through overnight before tapering off in the morning Friday, after leaving 3-6” for the morning report and possibly an additional inch or two during the morning after the report.
Brief ridging will be over the area Saturday before another wave in northwest flow crosses mostly north and east of us, bringing another surge of seasonably cold air and light snow showers with minimal accumulations for late Saturday night into Sunday morning.
Cloudy but cool and dry conditions are forecast for Monday before the West Coast ridge builds and moves eastward over the Rocky Mountain spine by Tuesday, bringing plenty of sun and warming mountain temperatures for the rest of the work week. However, temperature inversions will likely reform in the valleys continuing the cold overnight lows there.
Pacific energy from the west and cold Canadian air from the north are forecast to weaken the ridge sometime around next weekend or early the following week, and this may allow storms to once again affect our area.
