   The severe weather threat for Severe Thunderstorm Watch 189
   continues.

   SUMMARY...Severe risk -- mainly in the form of large hail and
   locally damaging wind gusts -- is ongoing in conjunction with storms
   in progress across parts of northern and central Texas.

   DISCUSSION...Latest radar loop shows a cluster of storms ongoing
   across western North Texas and the Big Country region, near and just
   ahead of a western Texas dryline extending from east of Childress to
   west of San Angelo.  The storms are occurring on the northwestern
   fringe of rich Gulf moisture (low 70s dewpoints) being advected
   northwestward across the eastern half of Texas ahead of the dryline,
   which is supporting strong instability (mixed-layer CAPE in excess
   of 2500 J/kg).

   With low-level southeasterlies veering/increasing to around 40kt at
   mid levels, shear sufficient to support updraft rotation has
   sustained several supercells, which have produced hail up to golf
   ball size.  As the low-level southeasterlies increase nocturnally
   into this evening, storms will continue to redevelop across the
   north Texas vicinity, along with continued severe threat.
