Notes:  Big Horn Mountains snow information is derived from U.S. Government SNOTEL measurments.  Sheridan snowfall measurements are derived from a combination of NWS (National Weather Service), Cooperator and, for more than a decade, my measurements.  Sheridan precipitation and annual temperatures are derived from the same sources as the snowfall.  Where my measurments have existed for several years, they are used in lieu of any other records for that period of time.  In some cases, data from only NWS as well as records including my data, may both be shown for comparative purposes.  Averages include all data collected.  Normals are averages of 30 year periods which end at the end of the last decade.  I.E. the current normal period began in 1981 and ended in 2010.
