The North American Drought of 1983–85 might have begun in April 1983. Dry conditions severely affected a number of states across the Midwest and the Great Plains. Many states also experienced a heat wave in the summer months of the first drought year. Temperatures were 100 °F (38 °C) or higher in multiple areas.[source?] Later in 1983 and the two following years, dry conditions began affecting south-central Canada as well, particularly Alberta, Manitoba and Saskatchewan. The drought may have been caused under a weak-to-moderate La Niña. That spell may have developed during the mid-spring of 1983.[2]
Midwestern States
Almost all the counties in the State of Indiana[3] and large sections in Illinois[4] were given a drought disaster declaration because of dangerous heat spells. Very dry conditions were also present alongside the heat. In Kentucky, the Drought of 1983 was second to worst in the 20th century. A large number of trees and shrubs became dormant during the drought and heat.[5]
In parts of south-central Canada between spring 1983 to early Autumn 1985, drought led to poor crops. That was mainly in Alberta, Manitoba and several regions of Saskatchewan.[7] June 1983 was somewhat wet for these areas. In July it was almost the opposite. August, Autumn and the following two years were also mainly hot and dry in the same areas.[7]
