   Concerning...Severe Thunderstorm Watch 467...

   The severe weather threat for Severe Thunderstorm Watch 467

   SUMMARY...Local severe risk continues across portions of
   southwestern Pennsylvania and a small portion of adjacent West
   Virginia and Maryland.  New/downstream WW not anticipated.

   DISCUSSION...Latest radar loop shows a band of storms moving across
   the mountains of southwestern Pennsylvania, and southwestward into
   northern West Virginia.  The strongest storms are ongoing near an
   MCV crossing the Indiana County vicinity, where transient rotation
   and possibly a weak/brief tornado touchdown may have occurred in the
   past hour.  Local risk for an additional/brief tornado and/or strong
   wind gusts will continue across northeastern portions of WW 467.

   Some instability extends northward into south-central Pennsylvania,
   east of WW 467, per RAP-based objective analysis.  This may allow
   local/limited severe risk to persist over the next couple of hours,
   east of the watch.  However, it appears that risk will remain
   isolated -- likely negating the need for new WW issuance.
