Hopefully, just one more night of chill, then warming to 70's for weekend highs.

Nonetheless, with our hard, rocky Sonoran desert "soil" here, standing/ponding water is accumulating over much of our yard. As would be expected for our area, NWS has flash flood watch already in place today and tomorrow, but currently, a flood advisory has also been issued for this morning.
3/13/2020 7:30 AM 1.29 M M M M Wow! Heavy rain overnight. At near bedtime (10:40pm), with TRW just underway, 0.27" had fallen during the day - lightning and thunder continued ... and by morning obs time, another 1.02" had accumulated. And as I'm writing this, another RW- is underway. Quite a wet last few days: 2.71", and counting! Good for the reservoirs, and replenishing our groundwater in the desert. :)

Very strong TRW with hail (up to 5mm across) around 1620-1635, within which heavy rain fell, in the vicinity of about an inch, in just that 15 min or so period. A 2nd TRW swung by, later around 1830. Very active, and cold aloft, upper low passing the SW US.

And, of course, in the low Sonoran Desert, there has been nearly no accompanying moisture (0.02" total for May) here as well. Welcome to the Desert Southwest, and we're not even into the summer months yet.

7/19/2020 7:30 AM 0.00 0.0 M M M Still waiting to break our typical spring-early summer drought (of course, being the lead-in to our monsoon). It's been about 4 months since having any precip to speak of (over a hundredth or so). But, it's rather cloudy this morning, for us, and it seems that some showers/sprinkles have passed a couple miles west of us. Our solar (PV) system is looking as poor today as it has for months! It's time to be getting some rain again... (hopefully).
7/20/2020 8:45 AM T M M M M OK - the monsoon is rumbling. Periods of sprinkles under considerable overcast. Nothing to measure at all yet, but drops of rain have fallen. Yesterday, our solar PV output was only 38 kWh; previously, we typically had about 60 kWh every day since late March (2020), when our system had been re-set. With such persistent cloud cover shaping up again for today, I would guess our PV total will be even much less today. We'll see! (Let's get those dewpoints back up into the 50(F)s or 60s, and get that rain going!) todayfallingenough drops drops
7/21/2020 7:30 AM T M M M M Nothing was in the rain gauge to measure, but a few times through the day (20th), sprinkles continued, so we have our "trace" again. Following on yesterday's comments, our solar PV total yesterday was only about 16 kWh (versus a normal sunny day here, of about 60 kWh), so we far and away had our cloudiest day of the last few months!

Abundant moisture (1.8" of TPW) reached us from the south, along with an unstable airmass (LI around -5). The few isolated TRWs (around Buckeye, and up to us just E of the White Tank Mtns) came through around 12:30 pm MST. This time, we lucked out, as the activity was not very widespread.

8/29/2020 9:00 AM 0.01 M M M M T at time of obs, even with a few sprinkles. This weekend period could be our last good chance to catch some monsoon moisture this year! NWS has flash flood watch out; dewpoints in mid 60s(F). We had only gotten one good (an inch) moist monsoon event way back in late July, while NWS-PHX also only had one decent event (at another time, a week or so ago). This had been looking like the "Nonsoon" here this crazy year of 2020! (Don't get me started on the substantial above normal heat we've had these last two months ...) :)
