Crowds thin, bases firm
Tuesday, January 21, 2014
Another beautiful bluebird day lured me out for my afternoon ski. The visitors for the Martin Luther King holiday weekend have left, leaving a mostly empty mountain. The first run on Shadows threw me around a little as the snow covering the terrain features was stiff and unforgiving. I opted for a cruiser below Duster and into Moonlight, which was very carevable. Then, up Sundown to ski the left side of Westside, which always has soft snow at the end of the day.
Up Sundown again and over to Typhoon to find pockets of soft snow, which continued in the recently thinned trees on Drop Out. The final run up top was upper Closet to Twister, which was firmer than I would have liked. The southern aspects of the trail near the bottom were beginning to soften from the sun, but it did not last long before the trail tilted away from south.
Why Not trees also had stiff tracked powder on the lower mountain, and the left side of Vertigo was a bit softer than most of the turns today. The longer range models do have a pattern change advertised starting in about a week, but details are evolving.
Nice weather interrupted by a small storm around Thursday and then lots of uncertainty
Sunday, January 19, 2014
Beautiful sunny and dry weather will persist through Wednesday as a large and stable west coast ridge dominates our weather, though a grazing wave in northwest flow will knock temperatures back a bit on Monday. A small Pacific storm will interact with the ridge early in the workweek and the result of that interaction as well as the effects of another impulse dropping down the east side of the west coast ridge from the north will determine our weather for Thursday.
I don’t expect much precipitation from this scenario as the strong west coast ridge minimizes impacts from the Pacific storm. Cooler temperatures and perhaps only light snow with minimal accumulations are expected on Thursday before current forecasts cut off this storm from the mean flow and leave it over California to our south and west.
There has been and continues to be a large amount of uncertainty in the forecast for next weekend and beyond. It appears that all models want to change the hemispheric pattern and either undercut or break down the west coast ridge. Numerical models often struggle with pattern changes like this, and the uncertainty with next weeks forecast has persisted longer than normal. At this point, there is no use guessing what our weather may be until more stability emerges in the solutions not only between models but also within models.
Snow in excellent condition
Friday, January 17, 2014
The last new snow that fell was during the day Tuesday, but temperatures in the single digits during the night and twenties during the day have kept the snowpack in peak condition. I was up on Wednesday for the leftovers, which were great, but I brought my narrower boards today since I figured the snow would lend itself to a carve-ier ski.
First run, as usual, was down the upper part of Closet and then a traverse into Shadows. Closet was great with the snow soft and grippy, and there were even patches of unskied powder that was still soft and deep. The sun was starting to make the the snow thicker and heavier in Shadows, so I retreated back to skier’s right to find terrain with less of a southern aspect. The low sun angle this time of year really helps to preserve snow quality. so most things tilted west of due south remain very good.
Then into Lower Shadows where the ridgeline on skier’s left also skied great, especially if you can plan to turn where other’s haven’t!. Next run was a ripper down the Sundown lifline which skied soft and consistent. Short, medium or long radius turns - it didn’t matter as the snow allowed you to ski however you wanted.
Next run was in the 3:30 trees, but I found this to boarded out - by which I mean that several snowboarders have evidently turned in similar places making huge ruts in tight trees that made the skiing inconsistent. So I ambled over the 3 O’Clock and found the right side just off the grooming track to hold more great carveable snow. I then took Duster for another run down Lower Shadows, but noticed Patrol had dropped the rope on the left side of Lower Shadows recently, maybe even today. There were several very steep but short southern aspect lines that held very consistent but deep, heavy untracked powder. I traversed to the right to regain the ridge and the colder snow before getting dumped back into the lifline.
Last run up top was upper Closet and over to Typhoon. Lots of soft snow, and even some untracked in the tighter lines, and that skied great. Then, a couple of runs over in the Why Not trees that skied as well as anything up top.
It looks like we are in a dry spell for at least the next week, and models are struggling mightily with a pattern change advertised for around next weekend, so get the snow now while its at its freshest.
Snow hangs through most of Tuesday
Monday, January 13, 2014
The Steamboat ski area reported 8” mid and 10” up top at 5am this morning, with about 2” of that coming overnight. Additionally, another 2.5” has fallen between 5am and 9am and it is currently lightly snowing.
The storm yesterday disappointed as a stabilizing and warming airmass not only stopped the snowfall that I expected to continue, but allowed winds to rake the ski area. By 1pm yesterday, much of the upper mountain had wind affected snow and skiing was not that great.
Another subtle wave in moist northwest flow passes over the area tonight, increasing snowfall again. The atmosphere should gradually cool through tomorrow afternoon keeping light snow showers going on the hill even as the valleys see some sun. I would expect 4-8” to be reported in the Tuesday morning report and 1-4” on the Wednesday morning report, all of which will occur during the day Tuesday.
The snows then stop for an extended period as the atmosphere warms and dries as the west coast ridge builds over our area. A grazing cool and dry wave to our northeast on Thursday will knock temperatures down a bit, but it appears the ridge and its associated warm and dry weather will continue through most of next weekend. Mountain slopes will substantially warm, though valleys will be on the cool side as temperature inversions reform and persist.
Storm about 4 hour late, but it’s here now
Sunday, January 12, 2014
Snows did not start until almost report time this morning, about 4 hours later than I had been anticipating. However, the Steamboat magic DID occur as scheduled, with 6” of snow falling between 5am and 9am. Temperatures at Storm Peak Lab fell from about 21F to the current 9F during this time while winds have increased from the northwest and currently average about 28mph with gusts to 45mph up top.
We are currently in moist northwest flow that is now expected to last through much of Tuesday, though snow amounts will be minimal by the end of that day. Since we have already received 7” of snow at mid as of 11am, and I expect periods of moderate to heavy snow to continue through today and especially this evening, I would expect a report tomorrow morning between 10” and 20”. This is consistent with yesterdays forecast of 6”-12” if the 4”-8” I expected by this mornings report is shifted to Monday mornings report.
Snow will continue through Monday with varying intensities, producing another 4-8” by Tuesday morning. Then, snow showers are expected to continue on the hill Tuesday as a trailing wave passes over the area, even as the valleys see some sun. Only 1-4” of new snow is expected during the day Tuesday as the airmass stabilizes and dries.
The west coast ridge is expected to build over our area in earnest on Wednesday, interrupted by a grazing cool and dry wave to our northeast on Thursday. It appears the ridge and its associated warm and dry weather will continue through most of next weekend, keeping mountain slopes warm but valleys cold as temperature inversions reform and persist. Model disagreements by the end of next weekend create uncertainty in the longer range forecast.
