5/19/2017 5/20/2017 8:00 AM 2 1.90 M M The gauge cap and flute had been removed on 5/18, so hopefully this is an accurate precip measurement. Total storm precip in our gauge was 0.99+1.90=2.89".
7/27/2017 8/03/2017 8:00 AM 8 0.64 M M I cannot remember for sure which was the first day of the accumulation period. About 0.45" of this precip fell over the weekend of July 29-30. Another ~0.2 fell during the week. Losing track!!
