7/2/2020 6:00 PM 0.01 M M M M There was actually some light showers in the Tucson area this morning that cumulatively resulted in the .01 in the gauge. I was at work watching radar for the Fort Huachuca local area and noted echo in and out of the area between 10:15 am and 1:20 pm. I also saw the .01 inch bucket tip of my Davis weather station on the phone app at 12:47 pm. The time noted below is when it began to rain with a little more intent. We got some pretty good thunderstorms and a third of an inch of rain in Sierra Vista this afternoon. I'm a weather technician at Air Force Weather Operating Location D, 3rd Weather Squadron providing support to the Army at Fort Huachuca. Sorry for the life story. No, I'm not really.
