10/8/2015 7:00 AM 0.12 M M M M 0.09 indicated by Davis TB, 0.11 in 8-inch NWS style gauge. 0.04 inches fell in the first half hour after ob time, weak TSTM RW- between 2 and 2:30 PM.

10/18/2015 7:00 AM 0.73 M M M M 0.68 inches in NWS gauge, largest discrepancy ever between the ground-mounted CoCo gauge and NWS 8-inch gauge. 0.68 inches indicated by Davis TB. Rainrate well over an inch an hour when squall with gusts to 40 mph hit last evening. NWS gauge is surrounded by natural desert vegetation, so not sure why this occurred unless it was a wind influence since the CoCo gauge was in the lee of the house and also surrounded by desert grasses.
10/19/2015 7:00 AM T M M M M A few isolated drops fell from an anvil overhang 2-2:05 PM! No other cloud around. Likely was the last, melted remnant of hail ejected out the anvil from unusually strong updrafts, something usually only seen in storms east of the Rockies.
