Mountain Weather for Friday, March 13th, 2015

CB Avalanche CenterWeather

Date: 03/13/2015

The overall weather picture today looks to remain unsettled, with increasing clouds due to daytime heating and potentially producing a few quick inches of snow across the higher terrain. The weather outlook for the weekend, and beyond, looks unseasonably warm as the dreaded “Rex Block” high pressure sets up over the western United States. Our next chance of precipitation, (note I did not say snow..) looks to be late next week. Grease those bike chains!

A broad trough is streaming Pacific moisture into Colorado this morning. The main dynamic forcing element for this system is afternoon convection, similar to summer thunderstorms, so snow showers will arrive this afternoon and intensify tonight. Passing cells could drop a quick 1″-3″ or so in some areas, and completely miss others. Trailing shortwave energy will keep weather unsettled into Saturday, before mild and dry weather takes hold by Sunday.

Another balmy day is in store for you Vitamin D lovers. High clouds will increase this afternoon ahead of a weak storm pushing across the Great Basin. A cool front aided by afternoon convection could produce some spotty showers tomorrow afternoon into Friday, without much for accumulations. High pressure returns for the weekend.

Date: 03/10/2015

Temperatures range from the low teens to 20s this morning, and light northwest winds blow at ridge top, as another day of tranquil spring-like weather is on tap again today. Temperatures will climb a few degrees higher than yesterday, with some convective cumulus forming this afternoon. A small, weakening weather system will spread over the area Thursday, but minimal snow accumulations are expected. High pressure re-establishes itself for the weekend and beyond.

Red Lady Bowl

CB Avalanche Center2014-15 Observations

LOCATION: Crested Butte Area
DATE OF OBSERVATION: 03/09/2015
SUBJECT: Red Lady Bowl
ASPECT: South East
ELEVATION: ATL-NTL-BTL

 

AVALANCHES: No new avalanches or signs of instability observed

WEATHER: Clear skies, light wind on summit

SNOWPACK: The snow was surprisingly cold (and not soft) at 2:30 PM. Thin to moderate crusts were prevalent until low in the bowl and the only moist/soft snow was found on the southern-most slopes below treeline.

Today is going to be clear, sunny and warm. Some states are having their spring break right now and if they’re in Colorado they’re going to love the weather as high temps increase each day as we head into the weak. For us powder starved CB peeps, we’ll have to wait until another week to get our fix. Chances of snow increase on Thursday and Friday but right now the storm doesn’t look to impressive.

Slate River, Paradise Divide

CB Avalanche Center2014-15 Observations

LOCATION: Kebler Pass Area
DATE OF OBSERVATION: 03/08/2015
NAME: Evan Ross
SUBJECT: Slate River, Paradise Divide
ASPECT: E-NE
ELEVATION: Near Treeline

 

WEATHER: Few clouds, warm temps, no wind.

SNOWPACK: The Slate River valley looks like a war zone and is an absolutely amazing sight seeing tour for an avalanche geek. Just about every piece of avalanche terrain faceting east or north avalanched during the last cycle. All the way from the Happy Chutes to Pittsburgh. There where many paths that ran, that I’ve never seen run before in the last 5 years. There were small pocket slides, too wide crowns extending for a couple thousand feet, too paths running full track into the valley.

Traveled near treeline and nearly found no signs to instability. One fact that could skew these findings is that fact that we had a hard time finding slopes that didn’t avalanche at some point during the recent cycle. I dug two crown profiles along the way with vary different findings and snowapck structure due to their HS.

1st crown profile at an elevation of 10,900ft on a NE facing slope, HS 263cm. Crown was 90cm tall, failing on squashed 1mm FCxr and 1f- hard. CT and DT tests produced no results on this interface.

2nd Crown profile was at ridgeline, elevation 11,600ft, NE facing slope, HS 138. Crown was 85cm tall, failing on 2mm FC and 4f- hard. ECTP-SC 31 with the whole black popping into the pit on a 31 degree slope.

Take home point: The snowpack felt good and stable where the old snowpack was deep before last weeks large storm. The snowpack was concerning and down right scary where the old snowpack was shallow before last weeks storm.

You can keep those bikinis and banana hammocks in the drawer today, as spring break weather will be on hold. A small shortwave will force its way over the high pressure ridge this afternoon bringing increased clouds and slightly cooler day time high temperatures. If we see an unlikely flurry of snow out of this system, then I’m going to go buy a lottery ticket. Monday will be the return to spring break with above freezing high temperatures and clear sky as we head into the new week.

Anthracite Mesa-Coneys

CB Avalanche Center2014-15 Observations

LOCATION: Crested Butte Area
DATE OF OBSERVATION: 03/07/2015
NAME: ADB
SUBJECT: Anthracite Mesa-Coneys
ASPECT: North East, East
ELEVATION: 9,400 to 10,900 feet

 

AVALANCHES: None on Coneys.
Schuylkill-observed N-SS throughout the entire ridge line. Most were D1 to D2 and covered all elevations (BTL/NTL/ATL). Appears that most convex slopes . Can see slides on moraines where lower skin track climbs and at the bottom of First Bowl to Thanksgiving Bowl.

Of note is that I didn’t see any slides in Redwell Basin or the gullies above the Gunsight Pass road between Redwell Basin and Wrong Chute.

WEATHER: Clear. No clouds. Calm. Warm

SNOWPACK: Tested a 30 degree slope on a convexity in the valley bottom. No cracking, whumping, or collapsing. Ski penetration was about 15 cm. No instabilities on skin track except heard one whump on ridge line above Cat’s Hat Glades Looked into these glades and didn’t see any failures.

Skied tree line between Cat’s Hat Glades and first bowl without any sloughing or movement. Lower 1/3 of slope was getting a tad heavier and a little sticky. Skis penetrated upper 18 cm of snowpack.
