8/25/2018 7:00 AM 0.18 M M M M I must say that in my 55 years on earth i have never witnessed getting so little from so much. Considering the ominous look of the skies i would have thought we were going to get absolutely dumped upon. I literally sat in a chair in the backyard for an hour as the thick black clouds drifted over ... and nothing! The rainfall i recorded all fell after the bulk of the initial storm had passed.
