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…

High Plains

With the exception of Colorado (which was mostly warmer than normal) and southern Kansas (which was 4-8 degrees warmer than normal), temperatures in the High Plains region this week were generally within 2-4 degrees of normal. Rainfall from the North American Monsoon occurred in parts of southern, central, and eastern Colorado, locally easing drought conditions in the eastern part of the state. Heavy rains in south-central and southwest South Dakota, and in southern Nebraska, northern Kansas, and east-central Kansas, led to locally improved drought and dryness conditions. Meanwhile, south of the heavier rains, flash drought continued to take hold in southern Kansas, where a combination of dry and hot weather worsened conditions. Extreme drought expanded in parts of southwest Nebraska, where short- and long-term precipitation deficits worsened conditions amid poor crop health. Drought also expanded in northeast Nebraska and southeast South Dakota, where soil moisture deficits continued to mount amid warm temperatures and dry weather. Extreme drought also developed in western Wyoming, where above-normal evaporative demand combined with short-term precipitation deficits to worsen conditions locally…

West

Rainfall from the North American Monsoon over the last few weeks led to some improvements in the drought situation across Arizona and New Mexico, where precipitation deficits lessened. Rain also fell in parts of Nevada, Utah, and eastern California this week. Temperatures were mostly 2-6 degrees above normal in the West region, though scattered areas were within a couple degrees of normal. Precipitation deficit amounts lessened enough for some improvement to ongoing short- and long-term drought in central Montana. Elsewhere, widespread drought continued this week across a large portion of the region…

South

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…

Looking Ahead

Through the morning of Tuesday, August 2, the National Weather Service Weather Prediction Center is forecasting heavy rainfall to occur from northern New Mexico and southern Colorado eastward across parts of the southern Great Plains, Mid-South, and southern Appalachians, including some areas currently experiencing flash drought. Pockets of heavy rain also may occur in western New Mexico and portions of Arizona. Elsewhere, rainfall is forecast to remain generally spotty, with many areas staying dry or mostly dry. During this period, hot weather is forecast in the Northwest, while hot temperatures are forecast over the northern Great Plains and cooler-than-normal weather is likely in the central Great Plains during the weekend (July 30-31). Temperatures are forecast to return to near-normal levels in these areas, and then may begin to warm as Tuesday, August 2 approaches.

For the period of August 2-6, the National Weather Service Climate Prediction Center forecast strongly favors warmer than normal temperatures over the eastern two-thirds of the contiguous United States, especially in the Middle Missouri River Valley. Below normal precipitation is favored in the central Great Plains, and to a lesser extent is also favored in parts of the Midwest and eastern Great Lakes. Above normal precipitation and below normal temperatures are favored in much of the western United States. Above normal precipitation is favored in east-central Alaska, while southwest Alaska is likelier to see below normal precipitation. Most of Alaska, excepting the far northern areas, is likelier to see below normal temperatures.
