10/7/2015 7:30 AM 0.87 M M M M Driving home for a few miles, around 1 PM yesterday (2015-10-06), amidst the flat terrain of alternating subdivisions and farm fields, we encountered significant street flooding from the heavy rains of the occurring strong thunderstorms. We had to pause a few times and wait to see if other vehicles were able to proceed, especially at a couple intersections; often, one side of the road was under water, and we drove in the other lane (when clear of approaching traffic).

Nearby (<0.5 mi away) local artery road (Camelback Rd) closed due ti street flooding. (This seems to happen often, with flat terrain amidst farm fields and subdivisions in the desert.)

And no precip likely in the next week. And top on, we're already in the second extended period of upper 80Fs (10F+ warm deviations) this month (including even one 90F earlier), and February 2016 goes down as hot and dry.

6/21/2016 7:30 AM T M M M M It was hard to go with Trace for precip, but there was a thunderstorm here last evening (2016-06-20) around 9:30 PM MST: lightning, thunder (a couple times), and some (few) raindrops - maybe 1 or 2 per square foot! I felt them and saw them on the ground, but of course, there was no evidence at the time of the rain gauge check in the morning. Also, the second heat wave of the month continued with another record: 116F, for PHX. (So far, PHX has had 6 daily record highs this month.)

Actually, it's interesting to see over about the last week that condensation water from the house A/C system is again accumulating in a catch bucket; that matches up with the recurrence of 50F+ dew points again. Yes, monsoon moisture lurks, and the "it's a dry heat" in the desert is no longer quite so much.
6/29/2016 7:30 AM 0.02 M M M M Feeling a little more like the monsoon season is upon us...

Also, of note, one thunderstorm cell was intense, and dynamic enough, to warrant a NWS tornado warning just to our S, to the SE of nearby Buckeye, AZ - no tornado touchdown reported, but quite unusual for the Sonoran Desert.

That was it; within a half mile down the road, those drops had nearly all evaporated. (Come on, Monsoon - let's get serious with some convection!)
7/19/2016 7:30 AM T M M M M Significant thunderstorms rained across more central and southern portions of the Phoenix Valley of the Sun last evening, but alas, we just had drops. "Close, but no cigar" for us yet...
7/20/2016 6:45 AM 0.26 M M M M Ah... finally, some substantial rain, overnight, for a change, having missed monsoonal activity around the area for the last few days.
7/21/2016 7:30 AM 0.00 0.0 M M M We're back to missing any convection, despite the modest monsoonal dewpoints (~60F) persisting. Also, of note, I should have added, yesterday, that yesterday's precip was the first real accumulation in our new rain barrel, set up after the last rain at the beginning of July!

7/30/2016 7:30 AM 0.02 M M M M Rain was not the prime player in last night's monsoon thunderstorm activity - the dust storm was! Hitting about 08:45 PM at our house, lots of outdoor furniture and stuff were blown around; the biggest was the 15', near 60 lb, Nova Craft fiberglass canoe, that ended up about 12' away (towards NE) from its original spot on a couple saw horses along the east wall of our house. The saw horses, and an aluminum ladder, were all still "attached". And desert dirt/dust was on everything (not an opaque covering, but just everywhere). At nearby Luke AFB - 07:45 PM NNE 39G52 and 09:36 PM SSE 26G36.

8/12/2016 7:30 AM 0.00 0.0 M M M One last aside on the Perseid meteors: with clouds of the last couple days mostly gone now, and the moon setting still early enough (or low on the horizon), I get out again and noted 24 meteors last evening in about 2 hours time around midnight. And the desert air temperature stayed around a balmy 88F during the watching ...

But then, it rained afterwards (0.22 in), but it stopped (and was measured) before we left on a long weekend trip to San Diego (at 10:30 AM on 2016-09-22 Thu). Until return, late on evening of 2016-09-25 Sun, only a trace was evident for the ensuing Multi-Day Accumulation, registered as of the 2016-09-26 Mon morning report.
