JANUARY

January, 2021 basically a boring weather month.  It never got very cold and it never got very warm.  A 45 degree spread for a month in Montana is very narrow and not common.  Although seemingly dry we ended up slightly ahead of the 19 year average in moisture and snowfall. Hard to believe but it was not nearly as windy as it was in January, 2020.
