11/17/2013 8:00 AM M 9.0 M 8.0 M Fairly strong snowstorm starting early afternoon and continuing into the early morning hours with high winds and heavy wet snow. Unfortunately, gauge was damaged during storm so no water content readings, only snow depth.
12/6/2013 8:00 AM T T M 16.0 3.21 A few light snow showers, very cold nighttime temps and little melting or settling. SWE sample had a good layer of ice at base making getting sample difficult.
12/7/2013 8:00 AM 0.05 0.5 0.05 16.0 M Light snow started early morning and continued through reporting time.
12/8/2013 8:00 AM 0.42 5.0 0.44 18.5 M Light snow with some heavier rounds all day and into early morning. Wind and cold with wind chills down to minus 21 degrees.
12/9/2013 8:00 AM T T M 18.0 3.56 Very cold and windy day with a few snow showers but little new accumulation. Wind chill temps have stayed in the minus 20 to 30 degree range with minus 35 this morning. Not a good day to be outdoors!
12/10/2013 8:00 AM T T M 15.0 M Just a few snow flurries and showers with little accumulation. Cold night with low temp of minus 14 degrees.
12/11/2013 8:00 AM 0.00 0.0 M 14.0 M Not quite as cold, low temp of minus 4.0, high of 13.7 degrees.
12/12/2013 8:00 AM 0.00 0.0 M 13.0 M Milder weather with high temp just over the freezing mark. Some snow settling and melting.

12/14/2013 8:00 AM 0.01 0.1 M 12.0 M Some light snow during the late evening and early morning hours with some accumulation.
12/15/2013 8:00 AM T T M 12.0 M Very light snow during the early morning hours with very little accumulation.
1/7/2014 8:00 AM T T M 15.5 M
1/8/2014 8:00 AM T 0.1 T 15.5 M Some light snow and snow flurries during the night and some lingering snow blowing in from the west this morning. Minimal accumulation overnight.
1/9/2014 8:00 AM 0.01 0.2 0.01 15.5 M Light snow during the late evening and into early morning, light accumulations.
1/10/2014 8:00 AM 0.21 2.7 0.22 17.0 M Snow during the evening and into the morning with accumulation. Lots of drifting due to high winds, sustained 30 to 40 mph.
1/28/2014 8:00 AM 0.30 4.5 0.32 21.5 M Corrected total snow depth. Snow, high winds and drifting. Snow started early evening and lasted into the early morning hours. Winds were gusting over 30 mph and wind chills around the minus 25 degree range with temps dropping just below zero.
1/29/2014 8:00 AM T T M 21.5 M Some light snow showers early and then clearing. No accumulation.
1/30/2014 8:00 AM 0.46 6.5 0.49 28.5 3.79 Snow wind and more snow. Snow started around 2 AM and was preceded by 30 to 40 mph winds. Snow continues at time of report. And trying to get a core sample of 30 inch deep snow into the outer gauge was a real treat.
1/31/2014 8:00 AM 0.97 14.0 1.02 33.5 M Snow, heavy at times persisted throughout the day with significant accumulation. Snow was fairly wet due to warmer temperatures, hovering in the 26 to 29 degree range.
2/1/2014 8:00 AM 0.34 4.5 0.37 34.0 4.31 Light snow during most of the day with a few heavy squalls moving through during the afternoon. Will update my SWE as soon as I get it melted down.
2/2/2014 8:00 AM T T T 31.5 M Just a few light early morning flakes, very cold temps this morning, the low dipping down to minus 16 degrees. Will get a SWE sample tomorrow, should be fun trying to get a snow core sample stuffed into the cylinder again!
2/3/2014 8:00 AM 0.00 0.0 M 29.5 4.26 No snow and a fairly mild day with sunshine and warmer temps causing quite a bit of settling of the snowpack. Low temp last evening was minus 3.1 degrees. The SWE sample contained about 12 inches of granular ice at the bottom, contributing to the high avalanche dangers in this area.
2/4/2014 8:00 AM 0.09 1.6 0.10 28.5 M Intermittent light snow during the day and into the evening.
2/5/2014 8:00 AM M M M M M
2/6/2014 8:00 AM 0.03 0.7 0.04 28.0 M Light snow accompanied by gusty winds from the west started very early this morning and continues at time of report.
2/10/2014 8:00 AM 0.16 3.5 0.19 35.5 5.38 Light snow pretty much continuous through the day and into late evening. Had a short break and it started again early morning. SWE sample contained quite a bit of granular ice for the lower 8 to 10 inches and barely would fit into the outer tube.
4/2/2014 8:00 AM 0.51 5.5 0.53 M M Intermittent heavy snow during the evening and into the following day with decent accumulation. Snow continues at time of report.
4/3/2014 8:00 AM 0.42 5.1 0.44 31.5 M Snow continued on and off with some heavier squalls blowing in during the afternoon and evening. Stronger storm moved through overnight dropping another 3 or so inches. Had to use an alternate and not as optimal site for total snow depth, due Lake Creek being open and not able to be crossed at this time.
4/4/2014 8:00 AM 0.19 2.4 0.21 31.0 M Snow on and off during the afternoon and into the evening with several strong squalls blowing in from the west. Much of the afternoon snow melted off due to above freezing temps but it did accumulate later in the evening. Low temp dropped to 4 degrees.
4/5/2014 8:00 AM T T M 30.0 M A light dusting of snow early evening with just enough to show up on the ground. Some melting again yesterday due to warmer (39 degree high temp) temps causing some snow melt.
4/6/2014 8:00 AM 0.26 3.2 0.27 29.0 M Heavy wet snow started around 4:30 PM, and turned drier later in the evening.
4/7/2014 8:00 AM 0.42 5.0 0.44 30.5 M Heavy wet snow throughout the day yesterday with squall after squall blowing off the south face of Mt. Elbert and off the continental divide. We'd get an inch or so and then the sun would come out and melt it and then the cycle would repeat. Temp dropped early last night and an additional 3 inches of drier snow fell overnight. Still some lingering showers at time of report. Welcome to springtime in the Rockies!
4/8/2014 8:00 AM 0.06 0.7 M 29.0 M Another day of snow, sun, snow, sun throughout most of the day with most melting off as it hit the ground making new snowfall amount a guess. Winds picked up early evening and the snow quit overnight.
4/9/2014 8:00 AM 0.00 0.0 M 27.5 M The first day in almost a week with no snow. Warmer and windy with a lot of melting and settling.
