In Arkansas, it was a mild start to the month. Storm systems and fronts went around the high, and brought several rounds of rain.

A couple of days later (the 3rd), a weak tornado (rated EF1) was spawned in Jonesboro (Craighead County) around 630 am CDT. Roof damage occurred at an apartment complex, and several windows were blown out. Fence and siding debris was also found.

On the 4th, there was a slow moving storm system in southwest Missouri. The system triggered thunderstorms in northern Arkansas. The storms produced torrential downpours and more than three inches of rain in parts of Baxter County. Damaging wind gusts downed trees a mile east of Vilonia (Faulkner County) close to 100 pm CDT. Before the gusts started, a man was injured by lightning while removing a hammock from a tree. An hour later, five boat docks were overturned on Beaver Lake roughly five miles southeast of Gateway (Benton County).

After the weather calmed down, more storms arrived from Oklahoma before dawn on the 5th. These storms affected the southwest counties. The clouds unleashed more than six inches of liquid near Foreman (Little River County) according to a local resident. At Winthrop (Little River County), Highway 234 was closed due to high water. A few miles southeast of Ashdown (Little River County), Highway 71 was down to one lane.
