Given this paragraph about the climate in Fairmont, West Virginia, what was the coldest month in the city's history, and what was the average temperature during that month?
Fairmont has a humid continental climate (Köppen Dfa) with very warm summers and freezing winters. However, it is not uncommon during winter for warm air from the Gulf of Mexico to raise temperatures above 50 °F or 10 °C, which occurs on average six times each January and over eight in December and February. In contrast, when very cold air from Canada moves into West Virginia temperatures can go below 0 °F or −17.8 °C, which can be expected during 3.2 mornings each winter, but which occurred on twelve mornings during the extremely cold January 1977, whose average temperature of 16.0 °F or −8.9 °C was the coldest month on record by 4.0 °F or 2.2 °C. Despite the abundant precipitation throughout the year, the relative dryness of cold air means that most precipitation is rain even during the winter: the most snowfall in a month being 46.5 inches (1.18 m) is November 1950, and the most in a season 77.4 inches (1.97 m) between July 1950 and June 1951. The least snow in a season has been 12.0 inches (0.30 m) between July 1918 and June 1919, whilst the wettest calendar year has been 1956 with 58.12 inches (1,476.2 mm) and the driest – as with all of West Virginia – 1930 with 26.25 inches (666.8 mm). The hottest temperature has been 108 °F (42.2 °C) on August 8, 1918, and the coldest −21 °F (−29.4 °C) on January 21, 1994.
