How common is it that Wunderground corrects their historical observations? They are recording a SPECI at 1:45 PM: https://www.wunderground.com/history/daily/us/ny/new-york-city/KLGA I also briefly saw it but it has been removed fairly quickly from METAR: https://metar-taf.com/history/KLGA The market however is currently fully pricing the SPECI published on WU. Does this mean they usually do not correct it?
