We compare the forecast against the climate normal for those exact calendar days, computed from 60 years of observations. The deviation shows how much the coming month differs from a typical one.
They are real temperature extremes recorded in Black Hammer, MN since 1960: the highest and lowest reading for each calendar date, with the year it happened.
