Areas affected...West central Arkansas

Concerning...Severe Thunderstorm Watch 126...

Valid 160344Z - 160515Z

The severe weather threat for Severe Thunderstorm Watch 126
continues.

SUMMARY...Occasional wind damage and/or a brief tornado or two will
be possible with bowing segments/mesovortices through 05-06z.

DISCUSSION...The bowing line segment across west central AR has
maintained intensity for the past 1-2 hours.  The downstream
environment is sufficiently buoyant to support strong updrafts.
Additionally, the SRX VWP shows a 40-50 kt rear-inflow jet and
low-level/deep-layer shear vectors (per LZK VWP) are oriented
favorably across the N-S line segment to maintain updrafts tied
closely to the leading edge of the cold pool.  In the near term,
these factors will maintain the threat for occasional wind damage
and a brief tornado or two with mesovortices in the line.  By
06-07z, the storms will likely move east of any substantial buoyancy
and are expected to weaken.
