KBOS report was low compared to vicinity reports; however ... SIT REP from Boston-area resident Judah Cohen noted via Twitter the strong accumulation gradient in and out Logan Field.
The context of the link is unclear. Each forecast stations verifying STP comes from the Daily Climate Report or the CF6 bulletin issued by the NWS.
HYA is the exception b/c climate data are not maintained for the station. METARs and unofficial reports are used only when the NWS bulletins don't report snowfall on a timely basis.
