I mean you see the pictures of cars buried and it wasn’t just Fall River. Of course they had near 3’ with those rates. It wasn’t that wet either out that way. Temps snuck below 32 early on. Once you get below 32F you’re off to the races. Not to mention that band had great snow growth too.
It also matters where and how you measure. There was a lot of wind. You can’t just stick a ruler in some area and think that’s what fell. Trust me, I deal with this a lot in my area. Also the PVD metars still had over 30” on the ground the next day. If he claims Fall River was legit why wouldn’t the same areas to the west that were in the same band not be legit?
