@ivo,
Thank-you for your reply. Here are two screenshots showing the same data from the Fourpeaked, Alaska RAWS station: the interface from the GOES satellite data feed and the incorrect temp on Windy.com. I suspect this isn't an isolated problem, are you polling these data from HADS? If so perhaps they have an error in their header/SHEF codes, I will attempt to track this down. For Alaska RAWS Mesowest is likely a better data source.
