The wait is finally over. After 106 straight days with no measurable rainfall in Tucson, Arizona the city has officially picked up at least a tenth of an inch. Ahhhh, refreshing! A preliminary rainfall report for Tucson showed 0.10" of rainfall as of 9 p.m. Friday. It was still raining around the city at the time of this article, so that daily rainfall report will likely be just a tad higher. Nonetheless, it's the first measurable rainfall since the city received 0.20" on February 28 this year! https://twitter.com/NWSTucson/status/1007787766271397889 While a little technical, yes; the image above shows the weather balloon launch from Friday evening in Tucson. Meteorologists noted the highest precipitable water value for June 15! Commonly referred to as Pwat, it's a measurement of the amount of moisture in the atmosphere. This specific moisture Friday was coming in from the tropical remnants of "Bud." These are 24-hour rainfall reports ending Friday evening, June 15. The remnant moisture from Post-Tropical-Cyclone Bud will stir up additional rain showers and thunderstorms across the Southwest this weekend.

This helps to draw in moisture and bring rain more often. Take a look at the monthly rainfall summary for Tucson.
