A strong upper trough dove southeast across the Northern and Central Plains on April 9th, reinforcing a cold front southeast into the Southern Plains. The approach of this storm system enhanced a southerly low level jet, which allowed for the return of a warm front north across East Texas, North Louisiana, Southern Arkansas, and extreme Southeast Oklahoma, resulting in very warm, humid, and unstable air in advance of the front. The combination of this increasing instability, wind shear, and strong forcing ahead of the cold front and associated upper level storm system resulted in a prolonged period of severe thunderstorms across much of the region, with numerous reports of large hail and occasional damaging winds across Southwest Arkansas. An isolated tornado also touched down across Southern Little River County along a line of severe thunderstorms along the cold front. These storms finally exited Southwest Arkansas during the early morning hours of April 10th with the passage of the cold front.

A strong squall line within an embedded supercell produced a broad swath of wind damage starting near Foreman and ending near Ashdown. The damage was mainly limited to snapped and uprooted trees laying in a southeasterly direction, although a few structures did exhibit minor roof damage from the wind, while many others were directly damaged by falling trees. The surveyed path length was around 17 miles, with a maximum path width around 8 miles. The estimated wind speeds ranged from 70-90 mph.

Tornado in LITTLE RIVER, ARKANSAS

Crop damage: 0.00K
Reported by: NWS Storm Survey

A brief EF-1 tornado with estimated maximum winds near 90 mph touched down near Little River 21 and the intersection of Little River 15 and Little River 713, where an area of concentrated convergent tree damage occurred in the midst of much wider straight line wind damage throughout the southern portion of Little River County. Damage to structures in the tornado path was very minimal. It is possible that the tornado path extends farther than what the storm survey indicated, but the actual survey length was limited by road access.
