-5.7 °Fcooler than the airport station KMFR, 6.1 miles away, on average over 8 readings; typical difference 6.6 °F

Against its reference: each temperature this station reports is compared with the nearest airport or climate reference station that reported within half an hour, up to 15 miles away. The figure is its reading less the reference's, on average, as both were reported; the typical difference is the root mean square. The difference in height is shown where both heights are known.
