10/9/2011 8:00 AM 0.34 0.0 M 0.0 M Frost was predicted ("28-33F"), but only got to 35F in my yard. Plants know it is Fall, though, with some going dormant although it has been warm until now. Fall colchicums (bulbs) were ruined by the rain, but the rest of the garden is very happy. Almost an inch, total.

In my neighborhood, I have seen nothing else. These are weak trees. Some people are still without electricity because of downed power lines from tree branches.

12/22/2011 7:23 AM 0.73 8.8 M M M I exchanged the cylinder about 8 p.m., but did not measure snow, so there surely was some settling, as it is fairly heavy. The early snow had a windy look to it (up against the side of the cylinder), but the a.m. snow was more settled. I'm glad I put out a new cylinder last night, though! It is still snowing lightly now, at 11:45 a.m., but the sun is out behind variable cloudiness.

1/8/2012 8:20 AM 0.15 1.3 M 1.0 M Very thin, slightly lumpy layer of ice at bottom. It had been warm, so I presume snow melted at first contact, then froze. It came down as regular snow. Real snowfall amount could have been a little more than reported.

1/25/2012 9:45 AM 0.07 1.8 M M M Board was in sun when I measured, and it was wet & heavy originally, so probably some compacting (sublimation?) of snow. Cylinder in shade. Bottom layer of snow (0.1 or less) was stuck to board.
1/26/2012 8:00 AM 0.00 0.0 M T M Snow still in completely shaded regions.

1/28/2012 8:00 AM 0.09 1.7 M M M Wet, heavy. Stuck only to green and totally shaded areas. Measured at 12:15 p.m. on 1/27. Wasn't sure how to enter that.
1/29/2012 8:00 AM 0.00 0.0 M M M The snow from yesterday (really 1/27) is only trace, on top of residual snow in fully shaded areas.

2/3/2012 7:21 AM 0.95 10.9 M M M Not sure if my precip is accurate. The cylinder was full to the top over about 2/3 of the surface, to the top where the "tail" would have piled up--so that makes me think I missed the precip. However, the snow around the cylinder was at precisely the same height, which makes me think about snow blowing in (but the depth of snow elsewhere was 10.9, basically the height of the cylinder, so maybe just coincidence. I think the truth is that I missed some. I forgot about taking a core sample from my board until it was too late.

2/8/2012 8:00 AM 0.01 T M M M Snow was stopping as I measured yesterday's, so I took this reading at 1:45 p.m. on 2/7. Had it not been cloudy, the sun would have been on the board by then. I think that is why snow was a bit clumped and frozen to the board--very hard to measure when there was so little.
2/9/2012 8:00 AM 0.00 0.0 M M M Much snow, even in sunny areas.
2/10/2012 8:00 AM T T M M M Flurries at 3:40 p.m., maybe at other times. Nothing in cylinder when I checked it.

This included the rain gauge, which gets afternoon sun, sits on cement and is surrounded at the base by bricks to keep it from blowing over.

6/27/2012 8:00 AM T M M M M I saw the rain streaking lightly in the air (I saw it against my garage, so it was close to the ground), but did not see it hit the ground--the sidewalk was clear. We were under a severe T-storm warning at the time and it was dark with high winds. I heard something, which could have been a few pieces of hail, but I did not see any in the grass.

1/1/0001 12:00 AM This was graupel, not sure if I should report. Largest balls were maybe 0.1-0.15 and then there seemed a continuous gradient of smaller ones. Only about 0.2" deep. All are approximations. Some fell at my location and same stuff 1 mile SSW of me. NA NA NA 10 3min no damage Continuous False
4/11/2012 5:00 PM I did not catch the beginning of the hail, but it did stop at 5:14. No hailpad, but very dense groundcover (pussytoes) caught hail and held it very visibly. 1/4" Pea Size 1/4" Pea Size Rice Hard|White Ice 14 3min minor leaf damage Continuous True After rain Before smaller hail vertical 1.5
5/5/2012 9:40 PM I don't know for sure, but there might have been a short, light small-hail episode at 9:40 p.m., not lasting very long. It was after the rain began. It just sounded like it, although I was too sleepy to get out and confirm it. It did make me look at the clock. NA NA NA False
1/1/0001 12:00 AM NA NA NA False
5/23/2012 9:10 PM This is an incomplete report because I was unable to go out, but I heard and saw the hail out the window. It only lasted 1 min! NA NA 1/4" Pea Size 1 2min minor leaf damage Continuous True After rain
