The 1936 North American heat wave was the most severe heat wave in the modern history of North America. It took place in the middle of the Great Depression and Dust Bowl of the 1930s, and caused catastrophic human suffering and an enormous economic toll. The heat wave started in late June, when temperatures across the US exceeded 100° F. The Midwest experienced some of the highest June temperatures on record. The heat wave and drought largely ended in September, though many states were still drier and warmer than average. Many farmers’ summer harvests were destroyed. Grounds and lawns remained parched. Annual temperatures returned to normal in the fall. Cotinue reading for more unusual weather phenomenon. Click here for the first image in this week’s things that look like other things gallery.
