10/9/2017 10/10/2017 8:00 AM 2 0.79 0.0 M Rain during Sunday the 8th was very intermittent and light (approx 0.02). Light to moderately heavy rain was rather steady Monday the 9th from predawn till late morning then tapered during midday.
2/5/2018 2/12/2018 7:00 AM 8 3.74 0.0 0.00 Multi-day measurement from open-mouth outer cylinder was 3.69 before evaporation. Adjusted to 3.74 for estimated evaporation of 0.05. This result is very close to nearby reports from HW and AA Counties for same period. And it seems reasonable to assume included individual daily amounts are quite close to those of MD-HW-38, Laurel 1.3 NNE, with stratiform precipitation episodes.

Sunday and Monday both had thunderstorms in vicinity during part of the afternoons, but not direct hits. Nevertheless, have not been able to determine if rains were very minor, trace to few hundredths, or more significant, near 0.1 or slightly more.

9/27/2018 9/28/2018 8:00 AM 2 1.71 0.0 0.00 Two separate rainstorms over these two days included thunderstorm previous early evening for 27th and general rain, heavy at times, from afternoon into overnight for the 28th. Could not confidently parse these two, but best guess is 0.51 for 27th and 1.20 for 28th.
