On the 26th, a large upper level storm system moved towards Arkansas from the southwest causing a stalled front in the Plains to move northeast across Arkansas. Thunderstorms along the front surged into Arkansas during the early morning hours of the 27th. On the 29th/early on the 30th, the atmosphere became very unsettled around the front, and storms flared up. Heavy to excessive rain overspread the area, and severe storms accompanied the storm system as well.
