Given all of the rain, flooding was almost non-existent locally. That changed on the 15th. The front had lifted a bit to the north by this time, and was draped across central Arkansas. Before dawn, a large cluster of thunderstorms hit areas along and north of the Arkansas River, mainly north and west of Little Rock (Pulaski County). At least two dozen reporting sites registered four inches of rain or more.
By 700 am CDT, a whopping 7.20 inches was reported at Damascus (Van Buren County)! That is two months of rain in just a few hours. Elsewhere, an impressive 5.95 inches of rain poured on Center Ridge (Conway County), with 4.90 inches at Ozark (Franklin County), 4.75 inches at Hattieville (Conway County), 4.10 inches at Conway (Faulkner County), and 4.08 inches at Coal Hill (Johnson County).
A subdivision flooded and cars were under water at Clarksville (Johnson County). It was the same story at Russellville (Pope County), and it looked like a lake near Arkansas State University. Roads were blocked off in Enola (Faulkner County) as water flowed over the pavement.
After dark on the 15th, isolated storms in the far north/west flooded Highway 59 near Natural Dam (Crawford County). There was a quick two to three inches of rain from Mountain Home to Gamaliel (both in Baxter County).
We went from flooding to severe weather on the 18th, mainly from northwest into central Arkansas. Ten miles southwest of Harrison (Boone County), a barn was destroyed by damaging straight-line winds. Trees and power lines were blown down just northeast of Subiaco (Logan County) on Highways 197 and 288, and also along Highway 22 at Midway (Logan County). Trees were toppled along Highway 27 at Havana (Yell County).
Isolated storms redeveloped on the 19th, mainly across the north. One storm produced quarter size hail at Rodney (Baxter County).
