Favorable upper level dynamics due to Texas falling in between the southern branch of the polar jet and the subtropical jet, along with a southwestern Texas shortwave disturbance moving northeast into southeastern Texas, created an environment conducive for the development of training, back-building thunderstorms. Thunderstorm clusters expanded eastward across areas of western and southern Harris County during the late afternoon hours. These storms produced copious amounts of rain that lead to the localized flooding of numerous metropolitan area roads. There were reports of small hail covering the ground over southern Houston.
