4/4/2019 7:00 AM 0.00 0.0 M M M Trace of moisture in the gauge the morning. Deck was wet, as well as inside and outside of gauge. Dew point was reached, apparently. (The dew point is the temperature to which air must be cooled to become saturated with water vapor.)
4/23/2019 8:00 AM 0.05 M M M M Hardly noticeable in the gauge, but .05 was indicated overnight. I don't its source.

This is high and notes seem to indicate this is a multi-day report instead of a 24 hour report. Changed report of 1.50 to NA until observer can be contacted to verify.

The hail fell before the rain began at about a 30 degree angle, indicating it was from the north. It was brief, lasting only about two minutes, producing no damage to outdoor flowers.
6/23/2019 8:00 AM M M M M M I thought I saw a cat AND dog in my rain gauge this morning, but it was just *almost* an inch of rain. And pollen. {EDIT: Observer reported 0.82 for new precip.

7/1/2019 7:35 PM 0.24 M M M M Light hail occurred for about 3 minutes during the first third or the rain. The hail was dime-sized, and smashed on impact, for the most part. What didn't break up immediately was gone in five minutes.
7/3/2019 8:00 AM 0.22 M M M M
7/4/2019 8:03 PM 0.27 M M M M Rain began, then pea-sized hail followed one minute later, lasting for about a minute. My split-leaf philodendron, in direct line of fire of the hail, suffered no damage, so I'd estimate the hail to have been slushy.
7/5/2019 9:20 PM 0.36 M M M M A fairly heavy pounding of hail occurred with this downpour. Hail ranging from pea to golf ball size fell for a period of four to five minutes.
