Its high elevation in the Black Hills makes Lead one of the wettest places in South Dakota and among the snowiest places in the contiguous United States with a mean snowfall of 183.9 inches or 4.67 metres.[17][18] During the cold and snowy winter of 1993–94, a whopping 364.7 inches (9.26 m) of snow fell and three years later snowfall totalled 324.0 inches (8.23 m).[17] However, frequent chinook winds mean that most of the enormous snowfall melts during the winter: the highest snow cover on record is 73 inches (1.85 m) on March 1, 1998 – during a storm that totalled 114.6 inches or 2.91 metres of snow (water equivalent 4.12 inches or 104.6 millimetres) over six days ending March 2. Mean snow depth in January is only 7 inches or 0.18 metres and the median even less at 5 inches or 0.13 metres. 12.9 mornings can be expected to fall to or below 0 °F (−17.8 °C), with the average window for zero temperatures being December 7 to March 3; on the other hand during winter 12.8 afternoons can be expected to get to or above 50 °F or 10 °C.[17] The coldest temperature has been −40 °F or −40 °C on February 8, 1936.[17]
