Different than spring: the fast and furious cloudburst. We just had one in the past three hours.

Look out the window right this instant, and there is a clear dry blue sky with a few little puffy cloudlets, and a pleasant breeze nudging the trees around.

But about two hours ago, the stormclouds moved in, dark grey, the wind picked up, and for maybe fifteen minutes it poured rain, anybody who was caught outdoors in it would have gotten soaking wet. You would never know this by looking outside now.
