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 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. Fire Danger computations are made at 12:00 Noon Mountain 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.
