National Current Conditions: July 20, 2022 - July 26, 2022
Flash drought continues to hammer the Southern Plains, Missouri and Arkansas, and western Kentucky and Tennessee. Meanwhile, the Southwest and Southeast remain wet, and drought conditions in Arizona improved this week. As of July 26, 2022, 43.61% of the U.S. and 51.94% of the lower 48 states are in drought.
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.
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.
