South Drought Summary

An area of low pressure over the western Gulf of Mexico brought some heavy rainfall and drought relief across portions of Texas and Louisiana. In Texas widespread 1-category improvements were made across the south and east. The rain did not reach the western and northern part of the state, however, where abnormal dryness (D0) and moderate drought (D1) expanded slightly. In southern Louisiana, the Lake Arthur station in northeastern Cameron Parish measured 11 inches of rain since August 25th. Abnormal dryness was eliminated here and to the north (Evangeline Parish) and northeast (Feliciana Parish). Moderate and severe (D2) drought conditions were reduced across much of northwestern Louisiana. Extreme drought (D3) was eliminated altogether in this region as well. To the east, D0 was reduced across a few counties in the north central part of Mississippi, while D1 expanded slightly in the northeast. In the southwestern corner of the state, D0 was also reduced. Aside from the eastern part of Tennessee, which received some precipitation from Florence, much of the rest of the state was dry and warm this past week. Abnormal dryness was expanded in part of southwestern Tennessee and northward into the central region around Marshall, Williamson, and Rutherford Counties. In Arkansas, D1 was expanded north over much of Miller County. Texarkana Airport has received only 39 percent of its normal rain over the last five weeks, with above-normal temperatures. This dryness was seen in eastern Oklahoma as well, where a large swath of D0 was added in eastern Oklahoma, stretching northward to nearly connect to the dry region in northern Adair County, which was also extended slightly southward.
