Event narrative

Trees downed along Highway 371 north of Magnolia and throughout parts of Columbia County.

Wider weather episode

A quasi-linear convective system (QLCS) advanced east southeastward into the Ark-La-Tex and Lower Mississippi Valley on June 26th. Ahead of the QLCS, the environment was characterized by MLCAPE values over 2500 J/kg, but deep-layer vertical shear remained relatively weak at only 10-20 knots and mostly unidirectional. Coupled with anomalously high precipitable water values in excess of 2 inches, the primary severe threat was from wet microbursts, in addition to damaging wind gusts from QLCS outflow. As a result, several reports of damaging wind gusts were recorded across Southwest Arkansas along the advancing QLCS.
