In 1943, a world record temperature increase occurred at Spearfish, South Dakota, when a Chinook wind caused temperatures to soar from 4 below zero to a balmy 45 degrees in just 2 minutes! An hour and a half later, the mercury free fell from 54 degrees to 4 below zero in 27 minutes. In 1982, the second of two colossal snowstorms struck Minneapolis in a 3 day period, overwhelming the Twin Cities with 17 to 20 inches of snow. Just two days earlier, a comparable snowstorm had buried the Twin Cities. The double Winter whammy produced snow depths around 38 inches and drifts that reached an incredible 10 feet!
