A crossing mid-level shortwave supported development of showers and thunderstorms with 2000-3000 J/kg of MUCAPE and weak deep layer shear. Anomalously high PWAT values, even for July, up to 2.0 inches were more than sufficient for any thunderstorms to produce high rainfall rates and flash flooding.
