In a display of Oklahoma’s famously chaotic weather patterns, August brought historic rains to portions of central and eastern Oklahoma while drought continued to intensify and spread over other sections of the state. A remarkable 6 to 12 inches of rain fell from northwest to central Oklahoma within 12 hours on Aug. 11, with a volunteer observer near Noble in Cleveland County recording 11.01 inches—a 500-year rainfall event according to NOAA statistics.
Oklahoma tried its best Al Pacino impression from “The Godfather Part III” during August, being pulled back into drought after nearly escaping its clutches completely thanks to record moisture the previous three months. The heat and dry weather roared back with a vengeance, however, and flash drought erupted for the second consecutive summer. Only 13% of the state was in drought on Aug. 8 according to the U.S. Drought Monitor, contained entirely in small patches across far southwestern and north central Oklahoma.
Three strong cold fronts brought the summer heat to its knees during August, but drought took advantage of a mostly dry month to proliferate across western Oklahoma. The far southeast was anything but parched, however, after several rounds of heavy precipitation and a brush with the outskirts of Hurricane Laura left it with nearly a foot of rain for the month. There were sporadic outbursts of severe weather during August.
