The Mid-summer 2012 Flash Drought in the Central Great Plains

The flash drought/excessive heat regime observed in July 2012 was centered on the central Great Plains with attendant heat spread across most of the U.S. Nebraska, Iowa and Illinois observed all-time top-5 driest mid-summer months on record. The drought condition came on fast most likely due to developing high-pressure aloft across a vast area of deep layer soil moisture deficit. Despite the wet soils in parts of the Great Plains a dry Q2 of 2021 climate is forecast and 2012 is a summer 2021 analog forecast year.
