US Drought Monitor Map Comparison of the 2005 and 2012 droughts

Notice that although a larger area in northern Illinois was included in extreme drought conditions around the same time in July in 2005, the percentage of the US covered in drought conditions was dramatically less than 2012! Incredibly, 64% of the country is in at least moderate (D1) drought conditions as of July 24th, 2012, whereas in late July 2005, just under 30% of the country was experiencing at least moderate drought conditions. Therefore, the 2005 drought, while significant in northern Illinois and northwest Indiana, was more of a regional event, whereas the 2012 drought is truly on a national scale.
