On the afternoon of the 24th, a stalled frontal boundary extended through northwestern Arkansas and far southeastern Oklahoma. This boundary began to lift to the north with widespread showers and thunderstorms initiating north of the boundary and affecting much of northwestern Arkansas. Recent heavy rains had saturated the ground and the additional heavy rainfall with this activity resulted in widespread flash flooding. Large hail was also observed with the stronger storms. The activity continued into the early morning hours of the 25th.
