10/7/2016 7:00 AM 0.05 M M M M Note - not for my location, but for the south eastern part of Ft. Collins: I was off Boardwalk close to Harmony at 3:45 when we heard one loud thunder and within 5 minutes hail that covered the ground. Average hail size was 0.25" with largest hail to 0.5"

11/18/2016 7:00 AM 0.18 2.6 M 2.5 M The first snow is usually hard to measure because of the warm surfaces - but this will certainly help to cool them off) When I got home at 3:15 yesterday, I realized I forgot to take out the inner cylinder, so I melted the accumulated snow and took a core at the same time from a wooden flat spot where the snow was accumulating. THe gage metled to 0.10. That core was 1.5" with a water equivalent of 0.12. Since it was breezy and the 2 measurements were not that different, I used the 0.12". This morning there was 1.1" additional snow that melted to 0.06". The total was 2.6" snow, 0.18" liquid.

I ended up taking a core out of the driveway because it represented an average depth around the yard at 6.7". The melted equivalent was 0.61. I'm putting an average of the gauge depth and the core depth of snow because one was fluffy and the other wasn't (6.8 +9.6)/2= 8.2

The last time we had shingles blow off was in December 29-30, 2008 when there was a significant period of sustained 40 mph+ and a gust to 83mph at Christman.

Dust blowing up on the car, dust blowing off fields and dirt roads, doors banging, house whistling, hard time walking into the wind, being pushed by the wind in the opposite direction. Christman field has sustained winds to 30s, gusts in the upper 40s, a few gusts into the 50s, and I believe it.

2/23/2017 7:25 AM 0.25 2.0 M 1.5 M The snow in the gauge was uneven - 1.5" on one side and 2.5" on the other side, so I went with 2.0". What was on other ground and level surfaces seemed slushier and measured 1.5" - so I put 2.0" of new snow and 1.5" on the ground. I saw a few drops of rain on my car windshield yesterday between 5 and 6 - so at least a trace yesterday late in the day. I knew it had snowed some during the evening because the sky was brighter ~ like a full moon. There was small graupel that looked like bouncing rain this morning - both at observation time and when the sun came up. Not sure if it was a result of this or something else, but the sky had a tint/glow of red-brown. Welcomed precipitation.
2/24/2017 7:00 AM 0.18 2.0 M 3.5 M The contents of the gauge were slushy when I got home yesterday, and I didn't get to check the measurment until this morning. It was very windy at times yesterday. At lunch I had to run an errand and the winds were northerly and the snow was moving horizontal. My car was facing south and the snow was drifted onto the windshield. Snow was also drifted onto LaPorte Ave. (runs east west) on the north side. I didn't have spare time this morning to, so I did a quick estimate of new snow: total on ground - total on ground from yesterday morning (3.5-1.5=2.0). Sorry I didn't have time to grab a core. Since it was so windy, this may be an underestimate of the actual precipitation.

The gauge had snow "pasted" on the west side. Looking at the temperature and humidity changes at Christman field, it likely precipitated ~ 5:45 AM. There could have been 0.01", but it's already evaporated, so I'm putting in T.

In what would be the cooler shady areas of the yard, there was and still is 0.1" of snow. If was awake when it happened I likely would have measured more. I had some slush in the gauge too. I can till see snow on roof tops around the area and there is snow (as far down as the trees and houses permit me to see) on the foothills just to the west of us (ie the east facing side of the east ridge of Horsetooth reservoir.

The gauge was dry.

4/29/2017 7:20 AM 0.42 2.4 0.35 M M I had forgotten to take the funnel and inner core out, so I needed to check the gauge when I got home at 5:20. I was out of town and my husband said it started with rain ~1PM. Snow mixed with rain around an hour later at 2PM. At 5:20 there was 0.8" snow on the ground (on wood where it wasn't melting so fast). A core measured 0.17. The gauge had 0.06 liquid plus snow in the funnel. The snow melted and added 0.17, for a total at this point of 0.23. At 7:20 this morning, there was 1.6" additional snow and the melted equivalent was 0.19. The core was within 0.01. It was hard to get an accurate estimate of snow since it melted some with the warm surfaces.
4/30/2017 7:00 AM 0.07 0.7 M M M I know snow accumulated in the morning and I remember seeing that is looked like at least an inch, but I didn't get out to measure it. Since it was in the mid-30's, it melted in the afternoon. I'm just putting in what a 10:1 ratio would be because it was "wet" snow.

I could tell this morning that we had gotten quite a bit of rain because there was an earthy smell in the air in the house and the ground under the trees was totally wet. By 7:05 it was mixed rain and snow and by 7:15 it was all snow and starting to accumulate on grass. BIG flakes.
5/19/2017 7:00 AM 2.51 7.5 2.51 7.5 M Wet spring storm. Changed from rain to snow at 7:15 AM yesterday (how convenient). Snowed heavily off and on all day and overnight. Luckily no major broken branches around our house. THe gauge was slushy this morning and melted to 2.29. The core had more melted value and was representative of various spots around the yard. Considering that there was wind and the gauge was underestimated and I may have even lost a little liquid through melting off the bottom of the board for the core, I went with the core value of 2.51.
5/20/2017 7:00 AM 0.01 T M 3.0 M We did have light snow lingering after 7AM and light rain showders in the afternoon. There has been significant melting and settling. I'll just wait and see how the early garden plants faired. Probably no fruit this year (making up for the abundance last year)

7/7/2017 7:00 AM 0.66 M M M M I was not home at the time but ~ 1.5 miles away, so times are approximate. Rain between 3 and 3:30 PM. There was likely rice to pea size hail as I observed a little plant damage, but nothing devastating. Lots of wind and rain in a short period because water backed up in a few spots and it was wet under covered areas that usually don't get wet. So the measurement may be an underestimate of what actually fell.
