I thought I'd do an unscientific study of the departure from normal over the last 2 1/2 years for locations found in the Local Climatological Data section of the NWS Websites. I'm using the unedited data that is showing there. Here are the departures from normal based on those pages for the following stations: If I'd hazard a guess, I'd say someone thought maybe Albany was reading too warm, so they tried to fix it, but they went too far. The problem starts in Aug of 2020, about a year ago, just like TugHillMatt said. It also appears as though Syracuse is reading too warm this year, while Binghampton was a bit on the cool side in 2019 and 2020.
