10/5/2012 8:00 AM 0.09 T M M M Snow started about 5 a.m. Not predicted, no snowboard out. Cylinder on cement, so could not estimate from that (cement warm). Not much, though, given amount on foliage.
10/6/2012 8:23 AM 0.02 M M M M Fine drizzle at time of measurement.
10/7/2012 8:20 AM T 0.0 M M M Despite predictions of snow and 23F, I only got trace (almost a fog, it was so fine, but it was coming down) in late afternoon. I only had the outer cylinder out, so maybe there was a little more. My low temp was 29F! Covered plants have dodged a bullet again--3 days of 32F or lower temps.

10/13/2012 8:00 AM 0.08 M M M M I suspect there may have been a little more, as I had only the outer cylinder out, and there were drops on the side that I could not get.
10/14/2012 7:15 AM 0.11 0.0 M M M May have been a little more, as at first had only outer cylinder out, and that caught a lot of rain drops that I could not get.

10/17/2012 8:00 AM 0.00 0.0 M M M Terrible wind during the night. Snapped a very tall spruce tree off half-way up (house was protecting the rest of the trunk--very close) down the block. Water gauge surrounded by bricks was, of course, blown over.

10/25/2012 8:00 AM 0.67 3.1 M M M It rained first, so maybe some of the snow melted before it was measured as snow. It was pretty heavy/wet snow. Roads and sidewalks melted, except for 6' of sidewalk that never gets sun.
10/26/2012 8:00 AM 0.04 0.3 M M M The ground is still warm, so my cylinder just had water in it. I could have lost some to evaporation. All sidewalks dry already.

7/29/2013 8:00 AM 0.03 M M M M Keeping track of precipitation is so useful for adjusting my irrigation system (turning it off on days after significant rain). From the looks of the garden, I just can't tell the difference between 0.3" and 1" without digging, unless I saw it rain. CoCoRaHS is useful to both you and me.

Sorry, no time, but it was evening while the sun was still up, about the time they were issuing tornado warnings east of here (DIA area). I saw some rain swirling around in my backyard 3 times close together in the heaviest of the rain.

9/12/2013 8:13 AM 1.37 M M M M Still raining at measurement. Heavy rain comes & goes, at times overflowing gutters, although I just had them cleaned. Usual amount of minor flooding around vulnerable areas of my yard, with a trickle in through a window at ground level. I have good soil drainage.
9/13/2013 7:11 AM 2.27 M M M M Yesterday 1.96" at 4:30 with sun out. There is a "central Denver effect" I've observed and have heard confirmed. Because of the build-up downtown (I live 3 miles east from the capitol building, the true center of Denver as a city--not counting distortion by Denver's airport way out east), clouds just go right around Denver for the most part now, or it rains and evaporates in the air (vergae). Not true 27 years ago, when I moved here.

4/7/2013 2:50 PM No hail pad. Only because I was at a window near my warning roof (plastic--the hail makes a loud noise) did I see any of this. It was very sparse (about 4-6" on flagstone), short-lived and melted quickly on the flagstone. Did not have enough to see angle. Rain ended close to 5 min later--also sparse, not quite confluent on flagstone. 1/4" Pea Size 1/4" Pea Size 1/4" Pea Size White Ice 1 1min no damage Continuous True Same time as rain Same time as smaller hail
