An upper level low pressure system shifted east from Montana east into the Dakotas on April 20th, with the attendant trough extending southward through the Rockies before ejecting east through the Central and Southern Plains during the afternoon and evening. A strong southerly low level flow ahead of this trough ushered very warm and humid air back north into the Four State Region on the 19th-20th, which primed the area with moderate instability ahead of an associated cold front that entered the region during the afternoon. Large scale forcing increased by mid and late afternoon through the evening along and ahead of the front and upper trough within the warm, moist, and unstable sector, enhancing scattered to numerous shower and thunderstorm development across portions of East Texas, Southeast Oklahoma, and Southwest Arkansas. Multiple reports of damaging winds and large hail were observed, with an isolated tornado also touching down in Midtown Tyler in Smith County. Localized flash flooding was also reported on the Texas side of Texarkana before the storms weakened during the evening with the loss of heating and reduced instability.
