It suddenly got several stops darker in my living room. Out my window, the sky lowered and a heavy dark mass of cloud began racing across the horizon. Right on schedule: one of those summer thunderstorms I mentioned earlier.
I wish the view from my apartment had less parking lot and more sky and trees. Nonetheless, this four-minute video gives a pretty good idea of the way these things go. During this storm the temperature temporarily dropped twenty degrees. But the dew-point and the temperature pretty much converged; now that it’s warmed back up by ten degrees, it’s like pea soup out there.
[Update: It turns out that this particular storm was especially violent and destructive. A whole lot of trees came down, and many people were left without power.]
