10/28/2011 7:00 AM 0.52 0.3 M T M Very steady rain throughout event, ending with change to snow and loss of timely tipping bucket data. Rain started yesterday, changed to snow around 1900, tapered off around 2300. Frozen accumulation mostly icy crust on car, somewhat less on snow board, trace on ground. Not worth trying to measure accurately!

From 0.12 from a tipping bucket (rain before changeover) + 0.83 from snowboard core soon after change to rain, I get 0.95. I may adjust it later from rain & snow in CoCoRaHS gauge.

That's all that's necessary to disrupt travel. An important stretch of I93 was closed for a while between the Hooksett tolls and Exit 8. Precip started before dawn, may be over with now.

5/11/2012 7:00 AM 0.11 M M M M Damp but not raining for most of the afternoon. Nothing worth calling "Heaviest Precipitation".

5/15/2012 7:10 AM 0.62 M M M M A little rain yesterday morning 0830-0940, resuming around 2200 with peak rainfalls at 2200 (0.26"/h), 0020 (0.19), and 0300 (0.22).
5/16/2012 7:00 AM 0.15 M M M M Light showers throughout day, times below are for a fairly steady period. Peak rain rate only 0.08"/hour, so I'm not including heaviest precip data.
5/17/2012 7:00 AM 0.66 M M M M Wx of the day were two Tstrms in the evening. The first storm was 2040-2110 with 0.36", the second was 2210-2310 with 0.29" and a couple more bucket tips at 2340-2350. Peak rain rates according to Davis were 4.50 and 4.88"/h, but heaviest 10 minute period was in the first storm.

5/30/2012 7:00 AM 0.97 M M M M The rain gauge had a ring of white pine pollen floating in the annulus. Pollen was so heavy in Nashua that cars were leaving tracks in parking lots. The rain here was heavy for a bit, some okay lightning, but nothing memorable. Not much wind. Davis tipping bucket reported 1.04".
5/31/2012 7:00 AM 0.01 0.0 M M M Restated from a 0.00" report - there was a solid 0.01" in the rain gauge but no bucket tip from the VP pro.

6/5/2012 7:20 AM 0.07 M M M M The Davis tipping bucket tipped in the hours 07, 09, 10, 15, 20, and 06. There was rain at both ends, so I'll leave the precip Begin/End fields blank. There was no heavy precip, so I'll leave those fields blank. But I'll report those times are Very Accurate. :-)
6/6/2012 7:30 AM 0.02 M M M M Davis bucket tips at 1630 and 0240. Clouds broke up for a while before sunset and let me see the Transit of Venus. Probably the largest angular size I'll ever see for Venus.
6/7/2012 7:30 AM 0.15 M M M M Showers around 1000 and 1900, dry in between. Duration info is nigh on useless.
