You got worse weather than I did, didn’t you, being north of here. Initial radar made it look to be a Flash Boom Bye. I don’t think I’ve seen cells grow so explosively. I don’t recall MA having such damaging twisters, either.
I may have grown a bit addled, being sixty; however, I’ve lived here all my life and I don’t recall EVER seeing a twister...
The last outbreak in MA that I remember being this bad was back on June 9, 1953 - the Worcester “White City” tornado.
