12/20/2011 9:30 AM 0.10 1.1 M 1.1 M I looked outside at 11 am and it was snowing lightly, and there was just enough accumulation to cover the deck. It snowed all day, but only accumulated about 1". At 2:15 am Tues. it was 15 degrees; at 10:30 am it was 28 degrees.
12/22/2011 8:45 AM 0.53 11.0 M 12.0 M Wedn. it was 25 degrees at 8:10pm, and 2 3/4 " snow had fallen. It started about 5pm. Overnight it was still 22 degrees at 12:30am (and 5 1/2" of snow) and in the morning, at 8:45am, still 19 degrees (& would remain that all day). I measured around the property and it was betw. 10 and 12 inches, but most of it was 11" deep. The gauge was full to the top, so a tiny bit may have fallen or blown out. (There was still some snow on the ground from the previous snowfall; it was somewhat hardened, and had some ice at the bottom in some places, and puddles that were frozen were "here and there")
12/23/2011 9:00 AM 0.02 0.5 M 11.0 M Nothing melted; it was too cold, espec. overnight when it went down to 9 degrees about 9pm, and 6 degrees at 1am.

At 9am today, Wednesday, it was 39 degrees; and it got to about 44 degrees. It was surprising that little snow melted. It is still icy at the bottom, and crunchy at the top layer. It was mostly 6" to 7.5". There was a light snowfall and thin layer of snow on the walkway in the late afternoon, but in the morning, my gauge was empty.
12/29/2011 9:00 AM 0.00 0.0 M M M Very windy afternoon, on and off. Usually the gusts stay pretty steady here, but it seemed to come and go today with longer than usual periods in between.

The heat is hanging on into the dusk hours, with it being close to 40 each night. This morning at 10am, it is 45 degrees. There is 4" left of snow. I measured at all the strategic spots and some had up to 6" but the majority was 4". And of course, there are some spots that are bare; these spots are always the first to dry up. And,my driveway is finally clear too. This morning it is sunny.

1/8/2012 9:00 AM 0.14 1.8 M M M Went to Estes Park on Sat. 1-7 morning, and it started to snow at 12 noon there. Came home about 5pm and roads were semi-icy under the snow, and slippery and auto accidents along the way. It took 4 times as long to get home (not counting 1/2 hr waiting for an accident to be cleared). It was wet,heavy snow.

1/19/2012 9:00 AM 0.00 0.0 M 0.7 M Very strong gusts of wind all day, like around 40mph. It got much stronger at night, and in particular around midnight, and lasted through the night. It was closer to 70 to 90 mph gusts. There was a long waiting period in between them. Usually when we get wind, the gusts come pretty frequently, so you hardly have a down time, but today and yesterday there were longer periods in between, maybe 1/2 hr. (?) In the morning it was still windy, but now steady wind, fluctuating in speed. It is back down to about 40 to 60mph winds Thursday morning. The 30 ft. pine trees are really getting whipped around. It's coming from all directions, it seems, by the things being blown around. Again, this is unusal; we usually experience most gusts of wind than steady wind. == Sunny both days. Wednesday it was 42 degrees at 8:30am. At midnight it was 38 degrees. On Thursday at 8:30am it is 42 degrees. == The snow was flying in clouds at the beginning of Wednesday, but by the end of the day, only the hard snow was left. On my deck, some of it is ice and 2/3 is snow about 1/2 inch thick. Even at 42 degrees, and being in the sun, the ice is hard.

About 4-5pm the melted snow turned to ice, and when I walked on the wooden deck it crackled, as I took each step, and not just where I could SEE ice, but any where on the deck. And, when I was under the deck, I could hear the water turn to ice and crackling! It was windy day.

It hit my garage door hard and water went under the bottom lip, that I had to mop up. Sun came out between the clouds after that. When the eclipse happened, the sun did come out, but set behind the mountains, so you couldnt see the best of it.

I called authorities and they said the Park fire was blowing smoke in our direction. (We didn't see any fires) This morning it was only 55 degrees at 8:40 a.m. The sky was white/grey overcast.

5/20/2012 3:35 PM There was a ton of dents in the paper, more than usual. about 1/3 were 1/4" apart, and others were 1/8" apart. At first it hit all the ground, but then when done, it melted very quickly, and there was only an accumulation in the SE corner of my deck, about 1" deep, and that quickly melted. It started off with a very heavy rain, and then the hail, which stopped, and the rain continued, quickly turnig to just sprinkles. It was close to 50 degrees?!

7/17/2012 2:50 PM Rain started about 2:50pm, and within about 3 minutes hail started, along with the rain. It was both 3/8" and 1/2" at the same time, with about 60% being the smaller and 30% being the bigger. This was unusual to have so many big ones. The heavy rain and the bigger hail hit the railings and made a big splash, that was about 6 to 8" tall. The rain was very heavy and ran in currents down the property, in the street, and driveway, causing minor flooding. The hail accumulated in corners of the house, about 1" in depth. The dirt/ground was covered with about 1" bare dirt (in between hail stones). No wind to speak of. The sky was 1/2 blue and 1/2 big puffy white clouds (2/3rds was white) with light grey bottoms. I have a pad, and it is almost covered in dents, but I havent counted it. 1/2" Grape 3/8" 3/8" Hard|White Ice 15 2min no damage Continuous False After rain Same time as smaller hail vertical 1
