Thanks to Northcoast Zeitgeist for turning my attention to this: the destructive storm that swept through the Midwestern to Mid-Atlantic states on the 29th has its own Wikipedia page.  Lots of great weather-nerd-speak, a.k.a. valuable things I probably learned to forget in Junior High science class contained therein!  Fingers and toes crossed for all y’all who continue to go without power in this heat.
