Another week of summer heat has kept drought concerns front and center across Oklahoma. While conditions have stabilized in much of the state over the past few weeks, dry weather continues to challenge producers in western Oklahoma as they await meaningful rainfall.
According to the Drought Monitor, the exceptional drought has remained unchanged this week. Conditions are present in Washita, Kiowa, Beckham, Woodward, and Roger Mills counties. Exceptional drought covers 2.10% of the state.
Moderate to extreme drought conditions in the current period indicate that 43.84% of the state is affected. At this point, 34.60% of the state remains drought-free.
According to the 6-to-10-day precipitation outlook map, all of Oklahoma is expecting near-normal conditions through August 8th.
This U.S. Drought Monitor (USDM) week saw very hot and dry conditions across areas of the Western U.S. and the Plains states where average temperatures soared well above normal levels—significantly elevating evaporate demand, especially across the Upper Midwest, Northern Plains, Colorado, and the Texas Panhandle where conditions deteriorated rapidly. Elsewhere, heavy rains across areas of the Mid-Atlantic states, Southeast, and the South, led to widespread improvements on the map in drought-affected areas. In North Carolina, rainfall totals for the week ranged from 3 to 8+ inches across the state leading to a significant improvement in drought-related conditions statewide. In the Northeast, recent isolated shower activity helped to improve drought conditions; however, the impacts of the longer-term drought continue to affect groundwater conditions in areas of Rhode Island and Massachusetts. In the Upper Midwest, drought expanded and intensified on the map, especially across Minnesota and Wisconsin where composite flash drought indicators were showing severe to extreme flash drought conditions during the past week. Out West, the Four Corners states continued to receive beneficial monsoonal rainfall with isolated areas receiving 2 to 4 inches. In portions of Arizona and western New Mexico, precipitation during the past 30-day period has been above normal, boosting streamflow and soil moisture levels while improving vegetation health. In the Pacific Northwest, short-term dryness has led to a dip in soil moisture and streamflow levels in areas of western Oregon and Washington. In the Great Basin, recent monsoonal rains have provided some minor relief to drought-affected areas of eastern Nevada.
In the South: On this week’s map, widespread improvements were made in drought-affected areas of Tennessee where rainfall has been well above normal during the past 30-to-60-day period across much of the state. In southern Texas, areas of drought expanded where hot and dry conditions have prevailed during the past 30 days. In the Texas Panhandle, short and longer-term dryness led to intensification of drought with year-to-date precipitation deficits ranging from 3 to 8+ inches. Looking at the reservoir situation, Water Data for Texas (July 29) reports statewide reservoirs at 78% full, with eastern reservoirs in good condition while numerous western, northern (Panhandle), and southern reservoirs remain below normal. Looking at climatological rankings for the past 30-days, record to near-record mean temperatures were observed in areas of the region, including in Brownville, TX (2nd warmest on record; +2 °F departure), Amarillo, TX (8th warmest; +3 °F departure), Gulfport, MS (4th warmest; +2 °F departure) and Jackson, MS (5th warmest; +2 °F departure). Average temperatures for the week were above normal across most of the region (1 to 10+ °F) with the greatest anomalies observed in the panhandles of Oklahoma and Texas.
In the High Plains: For the week, drought-related conditions deteriorated across the region including in the Dakotas, Nebraska, and Kansas where temperatures were well above normal, especially in western portions of the region where anomalies ranged from 3 to 9 °F above normal. NDMC’s flash drought composite map (July 27) also showed flash drought conditions developing with numerous drought impact reports coming into the NDMC’s Condition Monitoring Observer Report (CMOR) reporting system during the past 7-day period—especially in the Dakotas in relation to crop and rangeland conditions. Looking at climatological rankings for the past 30-day period, numerous locations ranked among their warmest or near warmest mean temperatures on record, including: Rapid City NWS Weather Forecast Office, SD (warmest on record; +8 °F departure); Custer, SD (3rd warmest; +6 °F departure); Bismarck, ND (5th warmest; +5 °F departure); and Fargo, ND (3rd warmest; +5 °F departure).
In the West: On the map, drought-related conditions deteriorated in areas of eastern Colorado, eastern New Mexico, southeastern California, and western Washington. Conversely, beneficial monsoonal rainfall led to improvements across Arizona, northwestern New Mexico, southeastern Utah, and northeastern Nevada. In the Southwest, an active monsoonal pattern (June 15 to present) has led to above-normal precipitation, especially in Arizona where percentages of normal have ranged from 150% to 250% above normal across southeastern, central, and northern portions of the state. According to the NWS Forecast Office in Tucson, AZ monsoon statistics, the following Arizona locations have received above-normal rainfall for the monsoon season: Nogales, Sierra Vista, Wilcox, Ajo, Globe, Apache Junction, Flagstaff, Kingman, Page, Prescott, Show Low, and Winslow. In Colorado, drought expanded and intensified on the map in response to anomalously warm temperatures, decreased soil moisture levels, and elevated evaporative demand. Looking at climatological rankings for the past 30-day period, numerous locations ranked among their warmest or near warmest mean temperatures on record, including: Montrose, CO (warmest on record; +3 °F departure); Dinosaur, CO (warmest on record; +4 °F departure); Grand Junction, CO (2nd warmest; +4 °F departure); Trinidad, CO (2nd warmest; +4 °F departure); Denver, CO (2nd warmest; +3 °F departure); Rock Springs, WY (3rd warmest; +4 °F departure); Casper, WY (3rd warmest; +5 °F departure); Salt Lake City, UT (5th warmest; +4 °F departure); and Pocatello, ID (5th warmest; +4 °F departure).
