It's hard to overstate our drought here. We haven't had more than a small amount of rain since mid-May (1/2 inch, tops, in our garden), and normal rainfall is about ~4 inches a month. We're 10 inches behind for this calendar year, and over 20 inches behind, for the last year & a half or so.
So, it's cause for excitement when a potential thunderstorm actually materializes (this is a normal occurrence in 'regular' years). Summer thunderstorms are very spotty in their distribution and rainfall amount.
We just had over 1/2 inch in about 20 minutes. What a relief to have something. And the clouds are dark with lots of thunderstorm possibilities predicted for tonight and the rest of the week.
Any bit helps plants, animals, and insects parched from lack of rain. I've just see the male hummingbird check out the vines (for insects?) near the window twice on his 'trapline' around the feeders, even in the rain.
