12/6/2017 7:30 AM T M M M M There were sprinkles last evening (~10:45 PM). If I had not felt nor seen those drops last night, there would have only been a zero for precip, as there was no telltale evidence in our rain gauge this morning. NWS-PHX did have several hundredths at Sky Harbor; but a very, very dry fall and early winter continue in the Desert SW US.

But, that was all, and just a tad of moisture in the rain gauge, far from any measurable amount. We missed a chance again; I see that PHX had at least a tenth of an inch. (The last rain here, over 0.02 inch, was way back, on 13 Aug 2017 - 4 months and counting for anything significant!)

Coming into the usually most dry couple months (with May and June typically mustering barely one tenth inch total), we're "hoping" this summer's monsoon will be substantial. For the water year, PHX (Sky Harbor) has had just 1.00 inch, versus the normal 5.21 inches. ...even for the desert, we have been dry, with a capital D!

For the water year, PHX (Sky Harbor Arpt) has only had 1.00" (as have we here), while the average should be just over 5". Still hoping the monsoon this year will be a good moist one - we can use it! We have now started to actually water some of our cacti on a weekly or bi-weekly manner.

The dewpoints here are now in the upper 50s (F) - first time in months, it seems. Tropical depression Bud is just leaving tip of Baja Calif, heading up S Glf Calif, with its moisture now reaching acrs S AZ. This rain opportunity here seems more of a tropical origin, than just the start of the Southwest Monsoon; but, we'll take whatever we can get!
6/16/2018 7:30 AM 0.11 M M M M Finally, some rain (and it's still lightly falling at time of obs)! The last bit of rain here was over 3 months ago (0.02" on 2018-03-11), and the last more substantial amount, of 0.17", was back on 2018-02-28 (3 1/2 months ago!). Thanks to Hurricane Bud for this taste of rain for now, and here's to hoping the monsoon will be good this year.
6/17/2018 7:30 AM 0.02 M M M M Today's amount came early yesterday, mostly just after yesterday's ob - this "event" total was then 0.11 + 0.02 or 0.13". An eighth of an inch - not much for over a period of more than (the last) 3 months!

That condensation typically indicates consistent dew point temperatures back in the mid to upper 50(F)s. Bring on the monsoon rains!
7/9/2018 7:30 AM 0.00 0.0 M M M No rain here last evening/night, but plenty of monsoon convection passed around the area.

7/10/2018 7:30 AM 0.16 M M M M Quite an energetic monsoon storm event swept across the greater Phoenix "Valley of the Sun" yesterday. We had only 0.16" of rain, but it was proceeded by a very strong wind/dust front around 5:30 PM lasting for tens of minutes. At nearby Luke AFB, report at 5:08 PM was for ENE 43G60 - felt similar here! Temps fell (pleasantly), from low 100(F)s into the 70s with storm passage. ... maybe more precip for us next time.

7/21/2018 7:30 AM 0.02 M M M M With some dry air to return next week and shut off the monsoon for a bit (as perhaps our hottest few days of this summer so far come Mon-Wed), we've had a modest first couple weeks of the monsoon with just over a 1/2 inch of rain total. Nonetheless, with so much of the last few weeks having dewpoints across the 60(F)s, and frequent heavier thunderstorms (out of the mountains north, east, and south) rumbling past, but not here, you just get the feeling that you're always missing out. That low desert cap (a too warm lower atmosphere) seems just too dominant. So, we'll wait to see if the rest of the monsoon returns sufficiently to help us dig out of our water year deficit (4 inches plus)!

7/31/2018 7:30 AM 0.04 M M M M Strong thunderstorms moved through portions of the west valley last night. An intense, very dusty outflow gust front blew by, around 8 PM - at nearby Luke AFB (5 mi away to NE), 7:47 PM ob was 91/61 with NE wind 58G69! Ob at 7:34 PM was 104/63 with initial jump of the wind at ENE 32G45. However, we continue to miss out on getting the benefit of any of the accompanying heavy rains, just dusty outflows here at our house. :(

8/3/2018 7:30 AM 0.05 M M M M Very strong thunderstorms in the area last evening - but little for rain for us here! Nonetheless, having dinner in Surprise, near Bell and Reems (about 9 mi NNE of here), around 7 PM, we experienced strong winds, heavy rains (tending horizontal at times), street flooding, and substantial tree damage (3-6" branches/trunks broken, and obstructing travel on the roads) - probably for a good half hour, it seemed. Back home later, it was still dry - our little rain came in the next hour or so. Still waiting for our share of a, at least a half inch or more, monsoon rain here this season ...

So, let's bring on some rain!! (This monsoon season has been very disappointing here, with just 1.25" total since start of July, and that, after a very, very dry 2018 water year so far up to that point.)
