Thunderstorm Wind in Lafayette County, Arkansas

Tree limbs downed and several chicken house were damaged at the intersection of County Road 19 and County Road 21.

A warm front extended well to the north into Northeast Oklahoma and Western Arkansas during the mid to late morning hours on March 4th while a cold front front continued to approach from the west. Pressure falls were strong in this region with over 2 millibar falls per hour. As a result, it was evident that a strengthening low-level jet was increasing warm and moist air advection northward. Meanwhile, surface observations otherwise indicated only marginally strong instability extending across the warm sector in Southeast Oklahoma and the surrounding Ark-La-Tex region. Regardless, this environment continued to support a damaging wind threat along the advancing squall line of thunderstorms and proved to be sufficient for widespread wind damage across much of Southwest Arkansas.
