This Week’s Drought Summary

The flash drought in the southern portions of the United States, especially over the Southeast and Texas, remains the prominent feature this week. As conditions continue to dry out coinciding with record warmth, deteriorations are widespread and rapidly occurring. Temperatures were varied over the United States this week, and much of the West, upper Midwest, and central and northern Plains were cooler than normal, with temperatures 3 to 6 below normal widespread. It was even cooler over Great Basin with temperatures 6 to 9 degrees below normal. In contrast, temperatures over the Southeast were generally 9 to 12 degrees above normal coming off a month when many locations set records for the warmest September on record. Temperatures were generally 6 to 9 degrees above normal in Texas and into the Midwest as well. Two prominent rain events came through the country in the last week. The first occurred at the beginning of the period when much of eastern New Mexico, west Texas and the Texas panhandle received rain and thunderstorms. A significant rain event moved through the southern Midwest and into the South, not only putting a stop to further drought development but also allowing for widespread improvements. Unfortunately, these rains did not get into the Southeast, where another hot and dry week continues to raise havoc on the region, especially to those involved in agriculture…

High Plains

Cooler than normal temperatures and the first freeze for the season were widespread throughout the region. Temperatures were 3 to 6 degrees below normal for most of the area. Above-normal precipitation was recorded over much of the Dakotas, eastern Nebraska and most of Kansas. Drier than normal conditions were reported over Colorado, western Nebraska, and southwest South Dakota. The region had abnormally dry conditions expand over eastern Colorado and slight improvement to the abnormally dry conditions over western Wyoming…


Cooler than normal temperatures dominated the region, with areas of Idaho, Nevada, Oregon, and Utah having temperatures 6-9 degrees below normal. Warmer than normal temperatures were experienced in New Mexico, where departures were 3 to 6 degrees above normal. Precipitation was widespread through central and eastern New Mexico and spotty throughout the Pacific Northwest and northern Rocky Mountains. The precipitation in New Mexico did allow for a full category improvement to the abnormally dry conditions in the southeast, east, and southwest portions of the state. In Arizona, further assessment of last week’s rain was done, with some further improvements made. Moderate drought and severe drought conditions were improved slightly in the central to south central portions of the state where the greatest impacts of the previous rains were observed. Due to a recent wet pattern, moderate drought and abnormally dry conditions were improved over the panhandle of Idaho, northeast Washington and northwest Montana…


Mississippi had their driest September on record and Tennessee had their second driest while Texas and Louisiana had their warmest Septembers. Oklahoma, Arkansas, and Mississippi had their second warmest. Significant rains over portions of west Texas and into the panhandle, northern Arkansas, southern Arkansas and northern Louisiana as well as much of western Tennessee allowed for some improvements in the region. Abnormally dry conditions were removed over much of the Texas panhandle and into west Texas. Moderate drought was also improved upon over the far northeast portion of the Texas panhandle and into western Oklahoma. A full category improvement was made over southern Arkansas and into northern Louisiana. A full category improvement was made in western Tennessee, northern Mississippi, and northern Alabama where the greatest rains fell. In the areas not impacted by rain, the warmer than normal temperatures along with dry conditions allowed for the flash drought to continue. Widespread degradations were made over Texas where areas of severe and extreme drought were expanded greatly. In central and southern Louisiana, abnormally dry conditions spread southward while a new area of moderate drought was introduced over eastern Mississippi.

Looking Ahead

Over the next 5-7 days, precipitation chances look to be greatest over the Plains and Midwest and into the Mississippi Valley. The greatest chances of precipitation are in North Dakota and through Missouri into Oklahoma. Conditions are expected to remain dry over much of the West, Southwest, and Mid-Atlantic into the Southeast. Cooler than normal temperatures are projected over most of the country with the greatest departures expected over the High Plains, where departures could be over 20 degrees below normal. Warmer than normal temperatures are expected over the Southeast and New England with departures of up to 3 degrees above normal.

The 6-10 day outlooks show above-normal chances for cooler than normal temperatures over the High Plains and into the Midwest while the best chance for above-normal temperatures is along the southern portions of the country from the Southwest into the southern Plains and into the Southeast. The best chances for recording above-normal precipitation are over the eastern portions of the country, especially the Southeast, as well as over the Pacific Northwest and into the Great Basin. The best chance for below-normal precipitation is over the central Plains.
