The seemingly impenetrable heat wave and dry spell that had punished Oklahoma since early June continued through nearly all of July, giving Oklahoma the type of scorching hot weather unseen in the state since the brutal summers of 2011 and 2012. A strong cold front snuck through the heat dome’s defenses near the end of the month to bring some relief, but the damage was done. The combination of hot weather, a lack of significant moisture, and relentless sunshine combined to plunge Oklahoma into flash drought that had covered the entire state by the end of July.
