Did not get a precipitation end time but it had stopped well before measurement time.

10/17/2015 6:00 PM 0.52 M M M M Storm ending time last night approximate, and it rained and stormed a couple more times before sunrise. Observed precipitation fall rates noted were .08 inch/hour at 8:00 pm, .12 inch/hour at 8:30 pm, and .28 inch/hour at 9:00 pm. No other observations made after that time. Heard thunder around 3:30 am. Rained again briefly this morning between 9:45 - 9:50 am and again at 13:45 - 13:50 pm. The rain this afternoon only amounted to .01, so .51 inch fell overnight.
10/18/2015 6:00 PM 0.27 M M M M Thunderstorm with rain started precisely at 7:58 pm, but I'm not sure of the ending time.

10/21/2015 6:00 PM 0.55 M M M M I have two start times but no ending times so I will list them in notes. As I said yesterday, a line of training echoes had formed overhead with moderate rain beginning at 6:02 pm. This lasted off and on through probably 7:30 pm. Then we had an area of thunderstorms form to the southwest early this morning with thunder and rain beginning at 4:20 am and probably continuing until 5:40 am. There were periods of moderate to heavy rain with observed rate of fall at 4:38 am of .98 inch/hour, 4:40 am of 1.46 inch/hour, and 4:44 am of .55 inch/hour.

10/29/2015 6:00 PM T M M M M Heard thunder at 8 am, and then again at noon. Storms were forming on the mountains this morning, becoming more numerous by afternoon. Managed to evade any precipitation until just before measurement time.
10/30/2015 6:00 PM 0.33 M M M M Once again, no start/stop times but I can approximate the periods. Rain began just before measurement time yesterday and continued off and on overnight due to the 500mb cold pool lingering over the area. On my way home from work late last night I watched some very impressive cloud-to-cloud lightning associated with those core convection storms. I measured .10 inch around midnight. Steady rain decreased to very light drizzle just before sunrise and I measured an overnight accumulation of .22 inch by mid-morning. Just before sunset a cluster of thunderstorms formed at the west end of the Catalina mountains and drifted south into the city and dropped another .01 inch in my gauge.

11/15/2015 6:00 PM 0.11 M M M M There were three different precipitation periods today, so I will report start/stop times and accumulations separately here instead of in the Duration Information below. Rain first started early this morning at 3:22 am and rained lightly until 6:56 am. There was .07 in the gauge from this. Then it rained again, more convectively, between 10:50 and 11:14 am for another .04 in the gauge. Then another very brief shower from 1:04 to 1:06 pm dropped a trace. I heard one distant rumble of thunder to the west some time after this last shower.

I estimate the rainfall with that event near .45 inch. I even heard a distant rumble of thunder. There were a couple of post-frontal cold advection showers this afternoon, between the hours of 12 pm and 4 pm. Both showers had some ice pellets mixed in for the remainder of the daily total.

In particular I will be looking forward to the improved Davis rainfall measurement resolution of .01 inch. The Davis gauge is approximately 45 feet northeast and 10 feet higher in elevation than my fixed 4 inch rain gauge, which will continue to be my primary measuring instrument.

6/25/2016 6:00 PM 0.18 M M M M The first of hopefully many Monsoon season thunderstorms presented itself this afternoon. A classic bow echo formed just north of my house producing frequent lightning and very heavy rain. My gauge was on the southern edge of the heavier rainfall. The maximum observed rainfall rate was .71 inch/hour at 4:59 pm. I observed a wind gust from the NNW at 12KT gusting 27KT at 4:35 pm. And lastly, the temperature dropped 30 degrees F from 3 pm (103) to 5 pm (73). Also noticed a significant discrepancy between my 4 inch stationary rain gauge and the tipping bucket in my Davis weather station. The weather station reported only .12 inch, which I think might have been due to the anemometer interfering with the rainfall as it blew in on the northerly winds. I will continue to compare both values and of course post only the 4 inch stationary gauge measurement.
6/26/2016 6:00 PM T M M M M I sprinkled very lightly off and on all night from the dissipating remains of thunderstorms. The very bottom of my gauge was moist but that was probably a remnant from the previous day's measurement that didn't evaporate.
6/27/2016 6:00 PM T M M M M Just a quick sprinkle.
6/28/2016 6:00 PM T M M M M Another trace. Wife heard some sprinkles on the sky light around midnight. I heard some distant thunder about 1:30 am.
6/29/2016 6:00 PM 0.19 M M M M Nocturnal thunderstorms, the best thing about the Arizona Monsoon. A couple of really close boomers too. Highest observed rate of fall was .32 inch/hour at 2:28 am.
6/30/2016 6:00 PM 0.35 M M M M Another rousing series of nocturnal thunderstorms. Highest observed rainfall rate was 1.53 inch/hour at 2:38 am.
7/1/2016 6:00 PM 0.17 M M M M This storm produced very heavy rain in the southern part of town. We were on the edge. The maximum observed rainfall rate was .55 inch/hour at 12:27 pm.

Initial gust front arrived before 6 pm, at 5:40 pm, from the NNE at 10 gusting 25KT. Maximum observed rate of fall was 3:05 inch/hour between the times indicated below in the Heaviest Precipitation section. There was also about 5 minutes of pea-sized hail when a dissipating radar maximum reflectivity core moved overhead, but I didn't get the time of the event.
7/31/2016 6:00 PM 0.03 M M M M A much weaker line of thunderstorms moved through, dissipating as it approached. Then it re-intensified out to the west, producing quite a bit of thunder. Rain came in a couple of showers, the first logged below produced what was measured. There was another brief sprinkle between 2:15 and 2:25 am.
8/1/2016 6:00 PM 1.05 M M M M Large cluster of thunderstorms moved west through the southern part of the city. Thunder and lightning was nearly continuous.

9/7/2016 6:00 PM 1.07 M M M M Significant rainfall associated with tropical system Newton. The period of heaviest rain recorded below produced a rainfall rate of .59 inch/hour.

Then a line of showers moved through after 5:00 pm for the bulk of the precipitation. Maximum observed rainfall rate of .72 inch/hour during the heaviest precipitation period.
9/29/2016 6:00 PM 0.11 M M M M Still raining, but clearing upstream. Severe thunderstorms in the area. Maximum observed rainfall rate .71 inch/hour during heaviest precipitation.
