Mountain Weather Forecast for Saturday, February 14th, 2015

CB Avalanche CenterWeather

Date:

Okay! Now we’re talking… There is hope. We will see another very warm day with clear skies and light winds. Temperatures near 11,000ft look to approach 45ºF today, ahead of a colder disturbance clipping our area Sunday and Monday. The models were once showing the ridge centered farther East, shunting any moisture from reaching us, now centers it farther west, allowing cold, moist air to create some snow potential Sunday evening and Monday. Still quite a lot of uncertainty, and time will tell.

In the past few weeks, I’ve seen streams emerge from high elevation basins, sunny slopes melt back to complete dirt, and a migration of locals towards the desert for mountain biking or sun bathing.  I’ve only lived in Crested Butte for four years, but this pattern seems so absurd for a high Rockies mountain town at 9,000 feet in elevation, that I dug into some historical weather to see how unusual this weather has been.

Since the New Year, we’ve been plagued by both snowfall drought and unseasonably warm temperatures.  The temperatures have been the greatest anomaly this winter.  billy barr in nearby Gothic has an exceptional record of temperatures and snowfall dating back to 1974 (www.gothicwx.org).  As of Friday, February 12th, 17 out of our 43 days this year have seen record-breaking high temperatures.  There have only been two days in February that didn’t break a temperature record, and we are currently going on 8 days in a row of record high temps. I expect the next two days will break records too.  On February 6th, the temperature hit 52 degrees F, which was a full month earlier than we’ve ever seen temps reach into the 50’s.  I think my brother in Florida is having a colder winter right now.

Looking towards Red Lady Bowl and some dirt slopes down lower.  Last year on this date, I dug a pit on a similar slope as that dirt slope in the foreground and found a 2 meter deep snowpack.


Snowfall droughts this time of year aren’t quite as unusual as the temperatures we’ve seen.  I looked at both Gothic snowfall and records from the town of Crested Butte, which date back to 1962.  (http://www.crestedbutte-co.gov)  In Crested Butte, where the average snowfall in January is 41.6”, we got 10.6” of snow last month.  There have only been four other January’s that saw less snowfall in the past 52 years.    February is off to a rough start as well, with only a few inches.  If it makes you feel any better, the winter of ’76-’77 only saw a total of 3” of snow from December through February in Crested Butte.  Too bad they didn’t have fat bikes back then. Gothic has fared marginally better on snowfall.  They saw 27” in January, which is 41% of average and the 8th lowest January on record.  Gothic picked up 6” in February, which is on pace to come up at 21% of the 70” average for February. Thanks to a healthy November and December, Schofield Pass SNOTEL is sitting at 67% of mean (3rd lowest snowpack in its 30 year record), and the Mt. Crested Butte SNOTEL is at 80% of its mean.

As someone who loves the winter, I can’t help but feel gloomy over the past couple months.  However, models keep hinting at a pattern change coming later this month or in March, for the warm and dry high pressure ridge to shift west and put us back into the storm track.  We’ll see…  And also worth noting, the horrible snow year of ’76 to ’77, which was the lowest on record at 61” in Crested Butte, was followed the next winter by the highest snowfall on record, at 381”.  I’ll stick around next winter to see what happens!

Looking towards Mt. Crested Butte.  Looks more like late April than early February.

Mountain Weather for Friday, February 13th, 2015

Today, look for mostly clear skies, light winds, and temperatures pushing 40 degrees.

The Baja Low has re-established itself over, well, Baja once again…and that damn high pressure has strengthen over the western half of the United States…again. But…there is a war being waged in the Gulf of Alaska, as a firehose of Pacific moisture is bombarding the dome of high pressure and something has to give eventually. Early next week..the good guys finally prevail, and moisture begins to sneak its way into the Great Basin, along with colder temperatures. This may be the beginning of a larger scale pattern change…but we’ll humbly oblige with a few inches of snow to get things going around Tuesday.

About this date last year my back blew out from shoveling out from our 10-day huge storm. This year, my back is only slightly irritated from the sunburns from lounging on my deck. Its little things like this we can be thankful for as high pressure takes hold through the rest of the week, bringing a few clouds and slightly cooler temperatures than we’ve grown accustomed to. Don’t give up hope though, because models are agreeing on a return to active, winter weather around Sunday or Monday. Better late than never, February.

Kebler Pass Area

WEATHER: Clear, Cool in am. Warm in pm. Overall mostly light to moderate winds from NE

AVALANCHE / SNOWPACK OBS: A recent Wet loose from the ridgeline (probably Tue 10th) on SE @ 12,100 ~40* 2 small collapses along ridgeline (SE & SW @~10*) on thin faceted snow pack covered by wind hardened snow. Skied up to 40* on SE-SW without incident. Below 10,850 on S-SW aspects ~15:00 snow was unsupportive wet facets/DH with ski pen ~20-30cm, boot pen 1/2 way to China. Flats & SE were more supportive

If you are looking for fresh powder, Monarch got 7″ and it is still snowing there. Drive east. The trough responsible for this snowfall is pushing south across the eastern part of the state, bringing upslope snowfall but leaving our Elk Mountains on the leeward and dry side of the storm. Mild and generally dry conditions will accompany the high pressure that builds into the Great Basin and over Colorado through the rest of the week.

Crested Butte Area

CB Avalanche Center2014-15 Observations

LOCATION: Crested Butte Area
DATE OF OBSERVATION: 02/10/2015
NAME: Zach Guy
SUBJECT: Crested Butte Area
ASPECT: North, North East
ELEVATION: 10,000 ft

AVALANCHES: No signs of instability

WEATHER: Broken skies. Calm winds. I counted 4 or 5 snowflakes falling from the sky.. But they were pretty big.

SNOWPACK: A profile on a NE aspect below treeline showed the Jan 11 surface hoar layer 25 cm deep, with fist hard, faceted snow above and below. No real slab over the surface hoar and no results on this layer, and we didn’t see any signs of instability on slopes up to 40 degrees.

Crested Butte Area

CBAC2014-15 Observations

NAME: Evan Ross
DATE: 2/10/15
LOCATION: Coney’s
ELEVATION: 9,900-10,900
ASPECT: NE


Weather: Partly cloudy sky in the Washington gulch area with plenty of sun and warm temps to soften snow on sunny slopes. Farther west cloud cover looked overcast. Light winds for the most part.

Snowpack: Wet, gloppy snow surface below 10,000ft on sunny slopes and even some shaded slopes. Higher up the snow surface was cooler and crusts from the last few days where noticeable on slopes that had a more eastern tilt to them. Found buried surface hoar down 40cm below a 1f slab in the starting zone of coneys. Found the SH mid way down the bowl too, about 30cm down. Skied the bowl with many other tracks and still no obvious sings to instability.

A band of moisture and a cool front is moving southward from Northern Colorado early this morning. As it passes over the Elk Mountain, we will hopefully see an inch or two or snow, but there could be convective component that brings localized heavier showers. The NOAA discussion this morning mentioned the threat of an isolated lightning strike. As if we don’t have enough concerns to deal with this time of year in the mountains. The trough retreats and closes off to our southwest on Wednesday, bringing upslope dynamics to our east and a faint chance for some light spill-over snowfall. High pressure returns under dry northwest flow for the remainder of the week, bringing back warmer than normal temperatures.
