Thunderstorm Wind in McCurtain County, Oklahoma

Several large trees fell onto a mobile home west of Valliant on Sandpiper Road near the Choctaw County line. One fatality occurred at the scene when a 48 year old female was killed by a fallen tree. One injury was also reported to a male resident in the home.

A longwave trough dug south into the Southern Plains during the daytime hours of October 20th, with southerly winds increasing ahead of the trough helping to return low level moisture north from the Gulf of Mexico. Above normal temperatures were seen across much of the region as readings climbed into the mid 80s to near 90 degrees, which enhanced instability during the late afternoon through the evening hours across much of the Ark-La-Tex area. While an isolated severe thunderstorm developed over portions of East Texas during the evening, which moved into Northwest Louisiana before diminishing, additional strong to severe thunderstorms developed during the late evening through the early morning hours on October 21st across Southeast Oklahoma and Northeast Texas, which later pushed into Southwest Arkansas and North Louisiana ahead of this trough and associated strong cold front. These storms produced several reports of damaging winds which downed trees and power lines across portions of McCurtain County Oklahoma, before diminishing shortly after daybreak with the departure of this system.
