5/4/2015 7:00 AM 0.03 0.0 M 0.0 M My gut feeling is that this measured precip quantity is inaccurately low. The reason is that, in addition to light rainfall before and after, we had a couple of minutes of absolutely torrential rainfall in the afternoon. Two brief periods, totaling 2-3 minutes I would estimate, during which the rain was thuddingly loud and the individual droplets appeared to my eye to be extremely elongated -- several inches long -- and barely separated from one another; almost (but not quite) continuous streams, as though emanating from countless celestial hoses supplying micro-pulsed flows. And the density of said streams was high, high enough to significantly obscure distant vision. I think it is possibly a sight of rain that I have never seen before. After the two brief deluges I went out to check the gauge. As I often do, I tried to guess what measurement I might find. Tempering my excitement, I made a personal guess of 0.08 inches. Even so, the numbers 0.25 and 0.35 kept crowding into my head as I hurried out to the collector. I can only say I was surprised to find that the inner tube read only 0.03!! Nearly 20 hours later I remain puzzled. Although there was no hail or sleet or pellets of any kind, I can hardly believe that this reading is accurate. I wonder if it is possible that the presence of the funnel, coupled with the size and fierceness of the individual droplet impacts could have resulted in significant splash losses. I even briefly entertained the theory that... (due to keystroke limit, this Observation Note will be completed tomorrow)
5/5/2015 7:00 AM 0.17 0.0 M 0.0 M (Cont'd from 5/4): ...I even briefly entertained the theory that the narrow funnel spout caused a backup/overflow loss out the top of the funnel. I soon discarded that theory, since the capacity of the funnel itself is well over an inch and would have filled the inner tube to overflowing. Also, I did note that the ground, while certainly wet, was not puddled or soggy or squishy or running in rivulets, as perhaps might be expected if a third of an inch had fallen in a 2.5 - 3 minute time span just a few minutes before. Still, I wondered – and wonder still – only .03?? I wished I’d had another container set out (I do now) – one with considerable depth so as to make it impervious to splash losses. Would I have found a barely discernible (.03 inch) depth in such a container? Or if only I had not deployed the funnel and inner tube! I have also thought about this in snowfall terms, as follows: A snowfall rate of an inch per hour is significant. Three inches/hour I would rate prodigious. And, drawing on my 15+ years and nearly 5,000 COCORAHS observer reports, I find that the water content of new-fallen snow generally ranges between .05" and .15" of water per inch of snow. For simplicity’s sake let’s say the water content of snow is .10" of water per inch of snow. Now, if Sunday’s 3 minute rain measured .03", this equals a rate of .60" per hour, and such a rainfall rate would equate to a snowfall rate of 6" per hour!! Holy cow! I guess .03" in 3 minutes IS a lot of rain! What can I say? Watching that downpour on Sunday, it just didn’t seem – doesn’t seem even now, computations and rational arguments notwithstanding – it just didn't seem like a number as small as .03" did justice to the epic quality of the event. Turns out that weather observation is, among other things, a matter of the heart – an emotional experience – and emotion can be a powerful distorter of perception. We’ve gotta keep those emotions in check, and trust our measuring sticks. COCORAHS depends on it.

5/26/2015 12:41 PM Sudden hail fall, unexpected, no rain or thunder. Small stones -- bigger than rice, but a bit smaller than 1/4 inch. Air temp was 55 degrees. White ice. I thought they might be pretty soft because all stones had melted within 1.5 minutes of cessation of hail fall. On the other hand, stones were hard enough to bounce out of funnel in my collector. I counted seven "escapees" (with binoculars). Not sure how many stayed in. No pad. Sparse accumulation, perhaps 10-15% ground coverage.

5/26/2015 5:41 PM Hail begain at 5:41, fell for 1 minute. Rain continued. Hail fell again at 5:46 for 1 minute. Tiny stones. Melted almosted immediately. Very sparse hail fall altogether. NA Rice NA White Ice 6 1min no damage Intermittent True 10-20

6/7/2015 5:06 PM There was a 1-minute break in the hail from 5:13-5:14. This hailfall was a bit more extensive than the several I reported earlier in the afternoon.
