This Week’s Drought Summary
Drought persisted across much of the West this week, while flash drought over parts of the Great Plains, Ozarks, and Mississippi Valley continued to intensify and cause agricultural problems. Short-term drought also expanded over parts of the Northeast this week, where deficits in short-term precipitation and streamflows mounted in some areas. Conditions locally improved in parts of the Southwest due to an influx of rainfall from the North American Monsoon. Farther east into the lower Great Plains and Midwest, localized heavy rainfall led to improvements, including severe flooding in the St. Louis Metro area, which previously had been experiencing abnormally dry conditions. In Alaska, moderate drought was mostly removed after recent rainfall improved conditions there.
Weather across the South this week was mostly hot and dry, with some notable exceptions. Heavier rain occurred in southern Louisiana and southern Mississippi, as well as eastern Tennessee. Very localized heavy rain fell from east-central Oklahoma into southwest Arkansas. Temperatures across the region were generally 2-8 degrees warmer than normal, with the warmest readings occurring in Oklahoma, Texas, northern Arkansas, and the western half of Tennessee. Flash drought conditions intensified further in central and northern Arkansas, central and eastern Oklahoma, and in spots in western Tennessee, northern Mississippi, northern Louisiana, and eastern and southern Texas. Crop failure and related problems are widespread in the part of the region experiencing flash drought, especially in northeast Texas, eastern and central Oklahoma, and northern Arkansas.
