7/2/2011 7:00 AM 0.00 0.0 M M M Yesterday was day #36 of 100° or more temps and the 27th day in a row of 100° or more and this little microclimate in the Tucson Mtns. No monsoons here yet.

7/5/2011 7:00 AM 0.03 M M M M The recorded precip may be somewhat inaccurate as the majority of our rain was driving and pretty much horizontal. It was, however most welcome!
7/6/2011 7:00 AM 0.10 M M M M High winds and driving rain began at 1712; heavy "horizontal" rain continued til 1735 and lighter intermittent rains until 1835. Mtns probably blocked most of the heavier rains the area got. And, the directionality of the rain probably resulted in less being recorded than actual.

7/10/2011 7:00 AM 0.00 0.0 M M M Our little microclimate in the Tucson Mtns is still left out of the monsoon rains.
7/11/2011 7:00 AM T M M M M even recording yesterday's precipitation as a trace may be stretching it a bit. I felt the drops and heard them on the roof. That is about it!

9/14/2011 7:00 AM 0.27 M M M M Another evening of wonderful soaking rain so much needed as our YTD total is still under five inches. Thunderstorms less violent and winds less strong than days before.
9/15/2011 7:00 AM 0.09 M M M M The monsoons are going out with a bang; we have had rain every day for the past six days -- though only a trace on Sunday. Another brief but nice soaker. Lost power briefly several times.
9/16/2011 7:00 AM 0.02 M M M M The monsoon did not depart as predicted and while we got very little, there was a torrential downpour 30 miles to the east; over 5 inches TV reported in one section of town; man swept away in Santa Cruz river.
9/17/2011 7:00 AM 0.00 0.0 M M M It appears the monsoons are done for the year. Started very very slow in our little microclimate and ended well but not fantastic, as in other parts of the Tucson metro area.
9/18/2011 7:00 AM 0.00 0.0 M M M Beautiful warm, not hot, sunny day; saw what I think must have been a weather balloon high in the northern sky traveling very slowly from E to W; appeared as a bright object at the sun rose and disappeared from sight a half hour later.
