This has been another snow day. Looking at my graphs and charts, I see that my rain gauge counted precipitation at 01:10, 12:13, 20:22, 20:28, and 20:33.
The temperature at 01:10 was 33.4°F, and had been above freezing for many hours before that. I'm not sure whether that means there was snow around then, or if that's when it finally melted on its own.
The temperature at 12:13 was 35.2°F, and it had been gradually rising from freezing since 08:06, so it could have been snow from all morning finally melting. However, I know from direct observation and from sweeping new snow off my car that it was snowing (lightly) around that time, so that's definitely a good count.
The dirty data points are those of 20:22, 20:28, and 20:33. The temperature reached freezing at 16:51 and has stayed below ever since -- but the snow continued for a long enough to build up a fair amount in my rain gauge. I noticed the accumulation, and melted it down with an electric hair dryer. The snow measurement is accurate for the day as a whole, but it didn't happen just then.
