I have made this map in conjunction with WeatherMatrix, and this (my) website, with an objective to have an extensive collection of surface observations available from one page. White ID letters show official NWS airport observations. Yellow ID's indicate AWS stations. While a good amount of the AWS (yellow) station temperature readings are accurate... there are a number which have erroneous high temp readings. I have compiled this list of AWS sites... showing which stations are most likely to have incorrect (too high) maximum temperature readings.
