You proved my point. The same thing happened at KBOS several years ago. Ice reported with temps above 32 along with fog with T/Td spreads of 3F or more. That eventually got fixed. Even Legro at GYX has noticed this about MHT.
It probably was snow given the obs nearby too. I was in Abington and there was some mangled crap falling, but I wouldn’t call it snow. You could see pieces of frozen crap sliding up on the windshield.
