Startled @3 a.m. to hear a loud clap of thunder, which repeated sporadically for over an hour! Radar revealed a tiny rogue cell in NW Calvert County, apparently the only one in the entire Mid Atlantic at the time. Such nocturnal T-storms occur infrequently in the summertime in our area associated with warm frontal passages but there was no apparent such mechanism, very strange! |
