In Atlanta many afternoons in the summer include a 3pm thunderstorm. Downed trees, washed out roads (I'm looking at you, Ponce de Leon where you branch off to Decatur), and plenty of thunder and lightning. You'll be positively drenched if you're outside in it at all. Seattle rarely if ever sees rain like that. A drizzle does mean there is actively water coming out of the sky. You will get wet, but a single layer rain jacket with a hood is sufficient to mitigate that. I suppose YMMV.
