According to the National Drought Monitor, moderate drought spread across most of Missouri, Illinois and Indiana, expanded in Ohio, Kentucky, and Tennessee, and crept further into Iowa. Severe drought engulfed most of Arkansas and advanced in southern Missouri, Illinois and Indiana, and in western Kentucky and Tennessee. Islands of severe drought appeared in northern Missouri and Indiana as well as central Illinois.
"And an area of extreme drought was introduced along the confluence of the Ohio and Mississippi rivers. This week was generally drier than normal, but in the midst of this drought depiction deterioration, heavy showers and thunderstorms dropped notable amounts of rainfall in local areas," states the monitor. "While not enough to make up for months of deficits, rainfall amounts of 2 inches or more locally held the drought expansion at bay in parts of Iowa, Missouri, Illinois, Indiana, Ohio and Kentucky."
In the southern Plains, the patchwork of thundershowers resulted in expansion of some D0-D2 and contraction of other D0-D3 in parts of Texas. "D0-D2 expanded in Oklahoma, with D3 expanding in the Oklahoma panhandle and into southwest Kansas. The impact boundaries were also adjusted in the southern and central Plains to reflect the changing nature of hydrological and agricultural (long-term and short-term) impacts," it states.
