That is 10" in W. Thompson. That was the storm that had massive subsidence outside of those main mega bands and caused a serious snowfall gradient around them. Reports in the surrounding areas were similar with 12.5" in putnam and 10" in hampton. If it was just one rogue report i might consider tossing it but there were many that fell off sharply once you got out of that main banding.
Also don't forget this was the storm where i had a very long conversation with @JC-CT about his 9" report in Columbia despite all the surrounding reports being in the 13-22" range. I believe him and thats why there is a hole over Columbia. Same thing with @metagraphica14.5" report in Salem.
It can be very hard to discern whats legitimate and what's not especially in a storm like this thats long duration, lot of wind, and subsidence outside of banding. But i definitely think those reports are legit considering everything surrounding it is in the 10-13" range around Thompson.
Here's the revised updated maps i just finished, ct, sne, tri-state are also updated
