Extreme Cold/Snow

edit

These will show the cold and snow extremes, by month, from all stations. These are not records for climate normals, but rather singular values. Annual snowfall records are records for one water year (usually July 1 through June 30).

Record high -> MaxT Max Min

Mean maximum -> MinT Max Min

Mean daily maximum -> MaxT Mean Min

Daily mean -> MeanT Mean Min

Mean daily minimum -> MinT Mean Min

Mean minimum -> MaxT Min Min

Record low -> MinT Min Min

Average snowfall -> Snowfall Total Max

Average extreme snow depth -> Snow Depth Max Max
