I noticed it was raining lightly again about 2:30 p.m. At 3:10 p.m. a more steady rain fell until about 5:30 p.m. After dark there was more light rain off-and-on until after 11:00 p.m. This morning I observed the first frost in my back yard.

10/9/2009 7:00 AM 0.01 0.0 M 0.0 M Light drizzle was present yesterday morning with a little bit of sleet mixed in later on which ended about noon. A brief, light rain shower hit about 2:00 p.m. Shortly after that I measured accumulation and removed the funnel and tube. From 4:55 p.m. to before 5:50 p.m. I observed the season's first snowfall. It was very light consisting of some large aggregates which only spotted the pavement.
10/10/2009 8:15 AM 0.08 1.0 M 1.0 M Light snow began after dark last evening. It ended around midnight, and it was not snowing at 6:45 a.m. However, it was snowing lightly at time of observation, and the major accumulation occurred within that 90 minute period.

10/14/2009 8:30 AM T 0.0 M 0.0 M It was quite foggy at time of observation. The trace could be fog that coalesced and accumulated in the gauge, but only the bottom of it had any water, so I assumed that it fell. If fog condensed, I would expect water on other parts of the gauge.

10/21/2009 9:30 AM 0.33 0.3 M 0.3 M Light drizzle began yesterday about 5:30 p.m. and continued throughout the evening. At observation time it was snowing lightly. Reported snowfall is only an estimate, since melting reduced the depth and the grass in the yard was taller than the snow depth.
10/22/2009 7:00 AM 0.13 T M 0.0 M Light snow ended well before 1:30 p.m. yesterday. All accumulation had melted by 3:00 p.m. At about 3:45 p.m. I noticed it was raining lightly, continuing until about 4:30 p.m. Then I noticed it raining again about 5:00 p.m., continuing until sometime before 10:00 p.m.

By 11:30 p.m. snow began accumulating on streets. It was breezy and snowing lightly at time of observation this morning. The core sample was taken about 15 minutes after the reported observation time. The snow depth is an average of 12 measurements from my back yard.

Freezing drizzle and light snow began at about 2:00 p.m. changing to only snow and continuing through the afternoon. By 5:30 p.m. snow intensified to moderate, and varied in intensity during the evening. At 11:00 p.m. about 5" of new snow had accumulated (0.37"), and gauges were swapped.

Unless I made a mistake yesterday, the only explanation that comes to mind for today's higher value is perhaps an accumulation of blowing snow from overnight winds. The temperature was 8F at 11:15 p.m. last evening but had risen to 17F less than an hour later when winds picked up.

12/24/2009 8:30 AM 0.33 6.0 M 9.0 0.57 Light snow began overnight yesterday and continued throughout the day ending after midnight. Winds began before dusk and created some drifts around the house, though none very deep. Total depth is an average of about 5 measurements in my back yard, and, because of the drifting, is only an estimate. Melted core is from a single measurement in the middle of my back yard, hopefully representative of the average total snowfall.

Sometime before 4:30 p.m. the intensity increased again to moderate. Surface temperatures were warm enough that very little of it accumulated, and streets/sidewalks were just wet.

Light snow yesterday evening started after 7:00 p.m. and ended before 11:00 p.m. I observed snow flurries this morning which ended before my late observation.

3/19/2010 8:30 AM 0.18 3.0 M 3.0 M Precip began before 5:00 a.m. today (already at least 1/2" of snow accumulation then). Frozen water drops were all over the outside of my gauge, so it's probable (though I'm not certain) that the precip started as rain then changed to snow. It was snowing lightly at time of observation. There was no snow accumulation on my front concrete sidewalk or driveway; about 1/2" of snow accumulated on my back-yard flagstone patio.
3/20/2010 8:45 AM 0.32 4.5 M 6.8 0.57 Light snow yesterday morning continued at varying intensities (very light to moderate) throughout the day. By 6:00 p.m., it lightened to flurries. By 9:00 p.m. even the occasional flakes had ended. Winds caused a little drifting, but nothing significant. I'm sure, however, that it affected the gauge accumulation, since today' core measurement (taken in the middle of my back yard) exceeded the total gauge measurements for this storm. The total snow depth is an average of 8 measurements made in my back yard.

3/24/2010 8:45 AM 1.39 11.6 1.51 11.5 1.51 This morning's "offical" gauge measurement (1.39") is in error and is greatly understated. When I retrieved the reading, at least 8" of snow was stacked on top of the gauge, and in my attempt to tamp it down inside, most of it fell off outside. I measured and reported what was left; I estimate the total to be near 1.75", because the precip began as rain which was heavy at times. (The core measurement also will be an understatement of the total.) Total snow depth is an average of 7 measurements made in various places in my back yard. ***** Yesterday morning started out sunny, but by noon clouds began rolling in. The significant weather change was declared by a single crack of thunder at 2:25 p.m. About 10 minutes later light rain began to fall. By 2:50 p.m. snow had mixed in with it, and the temperature began falling rapidly. At 2:50 p.m. there was another crack of thunder. By 3:10 p.m. the mixed precip had changed back to light rain. At 3:30 p.m. a full-fledged thunderstorm began with moderate rain. Less than 10 minutes later snow mixed with the rain. By 4:10 p.m. the thunderstorm had ended, but moderate mixed rain and snow continued to fall. Another crack of thunder was heard at 4:12 p.m. By 4:30 p.m. the precip had changed to heavy snow. At 5:30 p.m. there already was at least 4 inches of accumulation. Snow continued throughout the evening. By midnight the intensity had changed to very light, and the snowfall ended well before observation time.

4/6/2010 8:15 AM 0.11 0.0 M M M Just about 7 a.m. I heard noise coming from our roof. When I looked out my window, I saw what appeared to be snow pellets bouncing and accumulating on my garage roof. I held my hand out the window and captured some of them; they were quite uniformly 2-3 mm in diameter, with a coating of rime and a hard center. It was definitely not snow. I would classify it as rimed sleet, but the core of most of the frozen drops was milky, not clear; so it could have been very small hail. It started out moderate in intensity coming straight down and stayed that way for at least 10 minutes. It was still coming down lightly at 7:15 a.m. and ended before 7:30 a.m. It accumulated about 3/8" deep. (Observing the radar loop, an earlier precip echo passed over between 4:50 a.m. 5:15 a.m., so the accumulation amounts may not be only for this event.)

It was raining when I made my observation.
4/24/2010 7:00 AM 0.71 0.0 M M M Light rain continued after yesterday's observation and became heavy at about 10:00 a.m. At 11:20 a.m. the rain mixed and quickly changed to moderate snow. By 12:15 p.m. the intensity lessened to light and at 12:30 p.m. changed back to light rain. (The snow melted as it reached the ground, but I did see a thin layer of "slush" on concrete surfaces at times.) All precip ended at 12:45 p.m. There may have been a light shower or sprinkle yesterday evening (as observed by radar), but I didn't see anything.

The gauge (and the water inside) had a reddish color due to an accumulation of dust. Apparently yesterday's high winds raised dust in the air which was then rained/snowed out -- a rather unusual phenomenon.

Sometime in the evening (probably after 9:00 p.m.) the rain mixed with sleet, and by 11:30 p.m. the precip had changed to snow. At that late hour I removed the funnel and inner tube from my gauge. The funnel had a collection of sleet, and the tube hadd 0.67". The melted funnel contents added another 0.18". This morning the outer gauge contents melted to 0.33" for a total of 1.18". Precip had ended well before my observation.

Hail ended about 6:33 p.m. and the rain lessened to light. All precip ended before 7:00 p.m. I found it unusual that, for the first time, there was the equivalent of 0.05" of precip in the main part of the gauge even though the tube and funnel were properly installed before this event.
