Warming temperatures for the upcoming week
Thursday, February 21, 2019
A large, cold and slow-moving storm currently over Nevada will cross the Great Basin over the next day and bring heavy snowfall to the Desert Southwest and southern Colorado. North-central Colorado, including the Steamboat Springs area, has seen warming temperatures this Thursday morning in advance of the storm, with the Storm Peak Lab at the top of Mt. Werner reporting 21 F at 11:20 MST, around twenty degrees warmer than the temperatures the last two days.
We will see a chance of light snow showers this afternoon and evening as moisture moves over our area in unstable southwest flow with little accumulation. Snow showers should pick up during the day Friday as the storm approaches the Continental Divide and eventually brings some weak but moist and unstable northwest flow to northern Colorado. Snowfall amounts for our area will be light as the the bulk of the snows will be to our south, but we could see 1-4” by Friday evening before showers taper off and end for another quite cold start to Saturday.
A trailing wave from the northwest brings another surge of cold air along with a chance of snow showers for Saturday afternoon and evening that will bring only light accumulations at best by another cold Sunday morning.
Meanwhile, a rebuilding ridge of high pressure in the Gulf of Alaska will be undercut by a strong Pacific jet stream early in the work week, and this will allow warmer air to cross the West Coast and penetrate inland. Additionally, some upstream Pacific energy is forecast to be diverted southward and form a strong storm well off the West Coast underneath the Gulf of Alaska ridge. This combination of westerly and southwesterly flow impinging on the West Coast will force the jet stream just to our north early in the work week, with the best precipitation likely to occur between the I-80 and I-90 interstate highways.
There is weather forecast model disagreement as to the strength and evolution of the storm underneath the Gulf of Alaska ridge, and this will affect whether a transient ridge of high pressure builds over the Great Basin around midweek. A stronger ridge of high pressure would keep precipitation to our north through the end of the work week, while a weaker ridge will allow for light to possibly moderate snow showers. For what it’s worth, as of this morning, models were trending towards the warmer and drier solution.
Regardless, the weather forecast models seem to agree that the storm under the Gulf of Alaska ridge will be forced inland sometime around next weekend, restarting this winter’s stormy weather pattern as we head into March.
Start your ski day with toasty warm and dry boots! I use a boot dryer/warmer after every ski day, and the Happy Feet Dry-n-Warm boot dryer would be my choice if I ever had to replace my 30 year old and no-longer-manufactured look-alike. Just insert into your ski boots at the end of the day and leave them plugged in overnight. They become only slightly warmer than your body temperature so are safe to be plugged in for all footwear for days on end, though only overnight is needed for even the soggiest of liners. The ski boots are then thoroughly dry and toasty warm to start your next ski day!
Cold and generally unsettled weather on tap this week
Sunday, February 17, 2019
After thirty-three inches of snow fell at the top of the Steamboat Ski Area since Wednesday afternoon and raised the base up there to an even 100”, the currently sunny skies this Sunday morning over Steamboat Springs should give way to some scattered snow showers this afternoon. The upcoming work week will feature more cold and periods of light snow each day before moderating temperatures and drying skies are forecast starting around next weekend.
The current weather over the U.S. is dominated by an expansive trough of low pressure covering the western two thirds of the country downstream of a strong and dominant ridge of high pressure over the Gulf of Alaska. Several waves of energy and moisture will travel down the eastern periphery of the ridge off the West Coast, continuing the cold temperatures and chances for light snow over our area through the work week.
The first such wave will bring significant snowfall to southern Colorado, and we will see increasing chances of light snow the afternoon of Washington’s Birthday and overnight, though only 2-5” of fluffy low-density snow are expected by the Tuesday morning mid-mountain ski report.
Light snowfall is expected to continue during the day Tuesday as the storm passes south of our area and brings a reinforcing surge of cold air that will lead to steady or falling temperatures during the afternoon.
A quite cold Wednesday morning, especially if skies clear, should have 1-4” of snow for the morning ski report, with clouds increasing in the afternoon and maybe some isolated snow showers.
What appears to be the last storm in this cold series drops down the West Coast on Wednesday and starts light snow showers again over our area by Thursday afternoon. Trailing energy overnight and into Friday makes for an uncertain forecast as timing and position are difficult to forecast in this relatively chaotic atmospheric flow, but it does appear we will see some favorable, moist and unstable light northwest flow over our area by later Friday and into the overnight. This should lead to some accumulating snows that would be reported on a quite cold Saturday morning.
Meanwhile, additional Pacific energy looks to undercut the Gulf of Alaska ridge sometime around next weekend, and this may allow westerly flow to penetrate inland and bring warmer weather to the southern half of the West. I expect the details to change with such a major adjustement to the global circulation pattern, but right now the first half of next weekend looks cold and dry while the second half looks much warmer with some light snow showers possible along a frontal boundary separating the cold air to our north from the warmer air to our south.

Long duration storm cycle starts Wednesday afternoon
Wednesday, February 13, 2019
Snows have started in earnest this Wednesday afternoon in Steamboat Springs as the first in a series of storms moves across our area tonight. Two more storms will follow centered around Thursday and Friday nights, with the second one warmer and wetter than the first one and the last one much colder than the previous two. Snow showers will likely continue through most of a cold Washington’s Birthday weekend before ending by Monday as very cold air settles over the Yampa Valley. We could be looking at between twenty and forty inches of snow at mid-mountain by the time the storm cycle ends Sunday night.
Earlier in the week, the current storm had moved through a ridge of high pressure over the Gulf of Alaska and mixed with some cold western Canadian air. The southern section of the storm was left behind well off the coast southwest of southern California and will play a part in the wet and warm second storm for Thursday night. But for tonight, the northern part of the storm will bring moderate to heavy snows and westerly winds that will likely create difficult travel conditions.
I would expect 8-16” at mid-mountain for the Thursday morning report, with some Steamboat Magic continuing accumulations through noon at which point snows should diminish, but likely not stop during the afternoon.
Meanwhile, another Pacific storm, which will eventually become our third storm Friday night, travels over the top of the Gulf of Alaska ridge of high pressure and mixes with some air from the North Pole. This forces the wet and warm southern portion of the first storm over our area Thursday night with rising temperatures and more windy westerly to southwesterly flow. Snow will turn moderate to heavy again overnight with difficult travel conditions continuing, with another 6-12” of dense snow for the Friday morning ski report.
Weather forecast models have trended towards a break in the snow during the day Friday that may extend into the early evening, which will be the best time for travel, before the third storm in this series rotates inland across the Great Basin and begins moderate to heavy snows by Friday night. This storm will be the coldest of the three, and snows should be of the much fluffier low-density variety. The timing of the storm is still in question leading to uncertainty in the cold Saturday morning ski report, but by noon I would expect another 6-12” of snow at mid-mountain.
Meanwhile, another cold Pacific storm reinforces the cold air over much of the West through the end of the weekend and early next week. Snows will become more showery starting Saturday afternoon and continuing though the weekend before becoming very light or ending on Washington’s Birthday. The cold air will stick around for Tuesday and Wednesday as another very cold storm approaches our area, and there is considerable forecast uncertainty as to how this storm will develop.
I absolutely love this super-warm split-finger mitten-glove, and it’s perfect for the very cold week ahead! I’m on my second season with these and am very impressed with their durability and warmth, especially when combined with the standard HotHands handwamers. Three fingers sit together with the index finger separated, but there is enough room to scrunch all your fingers together while on the lift, which is especially nice if you have a handwarmer in the mitten-part of the glove.
Snows likely Monday and Thursday
Sunday, February 10, 2019
The current sunny skies and relatively warm temperatures in Steamboat Springs this Suday will give way first to clouds later today and snow and cold on Monday as a vigorous cold front passes through Colorado. A break in the weather is advertised through midweek before another storm brings snow back into the forecast for Thursday followed by a fair bit of uncertainty for the following weekend.
A ridge of high pressure over the Gulf of Alaska has directed cold air from the northern latitudes across the West the past week, and the next storm to impact our area tomorrow has already dropped 42” of snow in the past 24 hours at Heavenly! The storm will travel across the Great Basin today and bring a sharp cold front through our area early tomorrow morning. Rapidly falling temperatures, wind and heavy to intense snowfall rates are expected to accompany the front, with snow and winds quickly dying down after the front passes. The quickly moving storm will limit snowfall, and I now only expect 2-5” by noon on Monday before showers end by the afternoon.
We should see cold temperatures to start Tuesday, though they will quickly moderate at the higher elevations by later Tuesday and Wednesday as we see westerly flow ahead of the next storm. This next storm will travel through the ridge of high pressure in the Gulf of Alaska rather than over the top, and the trajectory limits mixing with cold air from the northern latitudes. Model trends have weakened the storm with a further north trajectory, but right now I still expect good snowfall during the day Thursday, with 4-8” expected by Thursday evening before the snowfall ends.
Friday will start chilly. though again westerly flow well in advance of the next Pacific storm brings warming most noticeable at the higher elevations. There is a lot of uncertainty for next weekend as models disagree on the track of these Pacific storms and whether the southern section of these storms are left behind off the coast of southern California. This is important for our weather as these left-behind storms may provide a rich source of tropical moisture that could be tapped by upcoming Pacific storms that follow similar trajectories. At this point, the weather for next weekend could be warm or cold and wet or dry, but this should be resolved by my next weather narrative on Thursday.
Stop battling cold feet! I’ve used the awesome Hotronic foot warmers from their beginnings, and can honestly say that each iteration of the product is better than the last. I have the S4 custom, attached to my powerstrap so they never fall off, and my toes stay warm for my entire ski day.
Moderating temperatures ahead of snow Saturday night and Monday
Thursday, February 7, 2019
After the powdercam showed 15” of snow in the last 2 days at the Steamboat Ski Area, a frigid arctic air mass has settled over much of the West. Low temperatures this morning were 0 F at the Steamboat Springs airport and -14 F at the top of Mt. Werner, and after a cold start to Friday, temperatures will moderate heading into Winter Carnival Weekend. A small storm will bring a chance of snow around Saturday night with a better storm forecast for Monday. Seasonably cold temperature and dry weather will follow for most of the rest of the work week before more snow is forecast by the following weekend.
As the current storm departs to the east, another strong and bitterly cold storm moving south along the British Columbia coast will dislodge a weaker storm off the West Coast that had earlier passed through a ridge of high pressure over the Gulf of Alaska. After another bone-chilling night tonight, the sun should return on Friday as the upper level flow turns to the southwest ahead of the small storm and brings warmer and drier air over our region. Temperatures will be slow to recover on Friday after such a cold day today, but will be noticeably warmer at higher elevations.
More warming is expected on Saturday ahead of the small storm that should bring overnight snowfall of 1-4” for the Sunday morning ski report.
Meanwhile, more Pacific energy moves through the Gulf of Alaska ridge of high pressure and starts the strong and cold storm off the coast moving eastward across the Great Basin on Sunday. The storm is forecast to weaken on its eastward journey, but will still be of moderate strength when it passes through our area sometime around Monday morning, though timing is currently uncertain. We should see a burst of snow as the cold front passes, with additional accumulations of light and fluffy snow behind the front in our favorable cold, moist and unstable northwest flow during the day Monday. I would guess 4-8” of snow will fall at mid-mountain by the time the storm ends by Monday evening.
Tuesday will start off unseasonably cold again behind the storm, with moderating temperatures and some sun expected as the week progresses, most noticeable at the higher elevations.
Rather than moving directly inland, like the past several storms, the upstream Pacific storm responsible for moving the Monday storm over our area is forecast to move southwestward and spend a day off the California Coast before moving eastward itself around midweek. This will allow the storm to mix with some moist subtropical air and direct clouds over our area near the end of the work week in southwesterly flow, possibly followed by another major snowstorm heading into the Washington’s Birthday weekend as the storm eventually moves through.
