This Week’s Drought Summary
Temperatures this week were generally cooler than normal west of the Continental Divide, while warmer than normal temperatures were common in the Upper Midwest and Northeast. Heavy rain fell across widespread sections of the eastern United States, in many locations due to the influences of tropical cyclones Fred and Henri and their remnants. The widespread rainfall led to condition improvements in areas suffering from abnormal dryness or moderate drought. Tragically, this led to a flash flood event with numerous fatalities in Tennessee. Parts of the Midwest, High Plains, and West regions received beneficial rainfall this week, which led to improvement in drought conditions in some locales. Many locations across the central United States that missed out on heavier rains this week saw drought conditions degrade.
Heavy rains fell this week across parts of central and northeast Texas (and adjacent southeast Oklahoma), in much of central and eastern Tennessee, and in northern Mississippi and Louisiana. A small area of short-term moderate drought straddling the Red River in southeast Oklahoma/northeast Texas received sufficient rainfall to see conditions improve out of drought. Heavy rainfall led to the removal of moderate drought in parts of eastern Tennessee. Northwest Oklahoma was left drier this week, and small areas of short- and long-term moderate drought expanded there and in adjacent southern Kansas. Temperature departures varied across the region and generally were not extreme in either the warm or cool direction.
