Here's my contribution from Wednesday. These images were taken on the Northampton/Hadley line off of 91N.
This particular cell had shown signs of rotation earlier in the afternoon as it crossed into MA, and as it continued unobstructed towards favorable territory near I91.
Given its structure, and presence of an inflow notch, I decided to pursue and set up south of its heading. This is looking towards its Southwestern most corner.
My internet had dropped so I didn't have access to radar or velocity profiles, but I'd be interested in seeing what it would have looked like in this timeframe on KENX, KBOX and the UMASS radar. Pictures were taken around 4:41pm.
Interesting day to say the least.
