All day and into the night it looked like it was just about to rain, but didn't as far as I know unless it rained overnight. We do have heavy dew this morning, so at least some of this measurement is likely dew, but a full 0.01" seems like an awful lot for just dew. Partly cloudy at obs time: H5 cirrostrati.

12/26/2016 12/27/2016 7:00 AM 2 0.29 0.0 M Light rain started pretty close to 2:10pm on 12/25 & continued past 5pm, exact ending time unknown. I heard more rain hitting my S windows at 2:06am on 12/26 and again, harder, at 3:44 on 12/26. Clear sky at obs time today, 12/27.
1/16/2017 1/30/2017 7:00 AM 15 1.33 T M Because this report spans 15 days, there was bound to have been some evaporation from the cylinder. On the other hand, the weather was generally wet or at least damp most of the time and overcast for all but one day of the duration, minimizing evaporation. Rough breakdown: 1/15 thunderstorm; 1/16 rain; 1/17 rain; 1/18 rain; 1/19 rain; 1/20 rain; 1/21 0.00 precip + a little sun; 1/22 0.00; 1/23 0.00; 1/24 0.00; 1/25 rain turning to a T of snow; 1/26 T of snow; 1/27 T of snow; 1/28 0.00; and 1/29 T of snow.
