While this is more geological than meteorological, there was an earthquake here today around 10:30 am. The epicenter was in New Jersey, the magnitude was 4.8, and it was felt from Boston to Washington DC.
I was down in the basement doing laundry at the time, and I could feel the floor shaking under my feet. It lasted about 30 seconds, and then subsided. When I got back up to my apartment and opened the door, Theo was sitting there staring at me with a weird look on his face, and then he immediately started racing around the apartment at full speed.
