   Concerning...Severe Thunderstorm Watch 623...

   Valid 152314Z - 160045Z

   The severe weather threat for Severe Thunderstorm Watch 623
   continues.

   SUMMARY...The threat for severe thunderstorms continues across WW
   623.

   DISCUSSION...A few supercells have developed across portions of WW
   623, supported by a moist/unstable airmass and modest 35-40 kt
   deep-layer shear. Primarily straight-line hodographs will continue
   to support splitting supercells capable of all hazards, though the
   tornado potential appears somewhat limited given the lack of
   low-level flow/curvature of hodographs. The primary threat will be
   for large hail (especially with any long-lived left split
   supercells) and damaging winds. Some additional convective
   development is anticipated as a frontal impinges on the northern
   portions of the watch area, with visible satellite imagery showing
   deepening cumulus indicating new initiation.
