1/28/2014 7:00 AM 0.00 0.0 M 10.5 1.99 Clear, 12F. The "cold front" from the NW reached the San Luis Valley by mid-morning, first by clouding up, then as the front came through (with surprisingly - no wind and not even strong breezes) the temperature started climbing as the weather front replaced the trapped cold air and broke up the inversion layer. I wasn't checking the thermometer frequently, but I saw a high of 42 degrees - which is the warmest I've seen since November! I ran a snow core late in the afternoon which I recorded yesterday, but am including today in case it got missed. Other than the crusted surface, the entire snow column is made up of large crystals. I think the expanding crystals have "fluffed up" the snow column which has stayed at the same depth for weeks, if not actually gaining depth. Some of my depth probes in the measuring area are showing 11 inches despite not receiving any new moisture since the 5th.

Looks like we may get some snow on the Sangres. The old timers say that it has got to warm up if we're going to get snow in the San Luis Valley!

2/3/2014 7:00 AM 0.00 0.0 M 11.0 2.03 Overcast & dang cold! 3F. Despite melting temperatures on Friday & Saturday, Sunday's snow increased the snow depth. Snow column has about 3 inches of powder, then ~1" ice crust with large crystals from the ice to the ground. Good avalanche conditions on a slope. Even with the last snows, we are below average snow pack. Just as the weather starts getting interesting we will be leaving for a couple weeks. The house sitter will not be keeping records.

10/16/2013 10/22/2013 7:00 AM 7 T M M It was blizzarding at 3am when I left home. I know that there was more precipitation than a trace - but that's all that was left in the open 4" tube.
2/4/2014 2/17/2014 4:30 PM 14 0.00 T M 48 degrees. Most of the ground cover snow has melted while we were gone - still some in drifts and in shade. Ground muddy - will wait to park trailer in the morning when the ground is frozen. Some precip was received while we were gone, but 4" gauge is dry. Good to be home.
