Driving back from Maine, fog gave way to light rain, then downpour crossing into New Hampshire. WBZ radio reported a tornado warning for southeast Essex County, MA. Rarity of rarity this far east. Sure enough, a tornado did indeed cut through Revere, damaging hundreds of homes (Globe story here). Driving southwest on Rte. 495, on the other side of the county, the tail end of the storm was visible ahead, giving way to a beautiful summer day.
