Notes:  Big Horn Mountains snow information is derived from U.S. Government SNOTEL measurments.  Sheridan snow measurements are derived from a combination of NWS (National Weather Service), Cooperator and, for two and a half decades, my measurements.  Sheridan precipitation and annual temperatures are derived from the same sources as the Sheidan 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 1991 and ended in 2020. Colored blocks in the upper right table indicate my values of the displayed data with red indicating an unfavorable value, yellow indicating a normal value and green indicating a favorable value. Fire Danger computations are made at 1:00 PM Mountain Standard Time for the afternoon of the current day. They should only be used for general information as values can change rapidly depending on specific locations and especially rapidly changing wind conditions. Open terrain with higher wind speeds may raise ratings by an entire rating category.
EOS=End of Season.
