Thunderstorm Wind in Columbia County, Arkansas

Power lines were downed along Highway 79 north of Magnolia.

A weak surface frontal boundary drifted south into Southern and Southeast Oklahoma, into Western and Central Arkansas during the afternoon and evening of May 25th. A very warm and moist air mass along and south of the front yielded ample instability over much of the Four State Region, as large scale forcing increased in response to a series of upper level disturbances that shifted east along the front. As a result, scattered strong to severe thunderstorms developed near and south of the front over portions of extreme Northeast Texas and Southwest Arkansas during the late afternoon and evening hours on the 25th, with several reports of damaging winds that downed trees, as well as isolated instances of hail. These storms gradually weakened by mid-evening with the loss of instability and the departure of these weak disturbances.
