The system was expected to pull warm/moist air northward over the front, resulting in widespread downpours.

 

The WSR-88D (Doppler Weather Radar) showed thunderstorms bowing out (backward C-shaped) in western Arkansas early on 04/21/2017. The bowing was caused by strong to damaging winds punching through the storms from behind (the west).
