Thunderstorm Wind in Little River County, Arkansas

Tree downed in Winthrop.

An expanding cluster of thunderstorms shifted across Southwest Arkansas during the morning hours on May 23rd. Some bowing became evident within these thunderstorms, suggesting at least a slightly organized cold pool. This convection occurred in tandem with a weak cyclonic mid-level circulation evident in water vapor imagery, and near the nose of an associated 40 knot southerly low-level jet. The forcing aloft, co-located with an axis of 1500 to 2000 J/kg slightly elevated CAPE, helped to sustain this convection throughout the morning with a few reports of isolated damaging wind gusts and flash flooding across parts of Southwest Arkansas.
