A west to east oriented shear axis aloft extended along the Middle Red River Valley of North Texas into Southeast Oklahoma to along the Arkansas/Louisiana border during the morning hours of July 3rd, which enhanced large scale forcing for the development of a concentrated area of showers and thunderstorms over portions of Southern Arkansas. A very moist environment was in place across this area as well, which enhanced rain rates as these showers and thunderstorms remained nearly stationary over much of Union County Arkansas through much of the morning hours after daybreak. Widespread rainfall amounts of 3-6 inches fell across Union County, with isolated higher amounts of 7-9+ inches measured across Northern and Central portions of the county. This resulted in widespread flash flooding across much of Union County, flooding and washing away multiple roads, with high water entering multiple buildings in El Dorado. These showers and thunderstorms diminished during the afternoon hours on the 3rd.
