↑  Mean monthly maxima and minima (i.e. the expected highest and lowest temperature readings at any point during the year or given month) calculated based on data at said location from 1991 to 2020.
↑  Official records for Williston kept at the Weather Bureau Office from January 1894 to June 1948, Sloulin Field International Airport from July 1948 until October 22, 2019, and the new Williston Basin Int'l since October 23, 2019.
↑  Only 22 to 24 years out of the 29 in the normals period were used to calculate the humidity normals.
