   Mesoscale Discussion 0353
   NWS Storm Prediction Center Norman OK
   0621 PM CDT Sun Apr 14 2019

   Areas affected...Western Pennsylvania and far southwest New York

   Concerning...Tornado Watch 69...

   Valid 142321Z - 150015Z

   The severe weather threat for Tornado Watch 69 continues.

   SUMMARY...The severe threat continues across tornado watch. The
   highest severe weather potential is across northern Pennsylvania and
   far southwest New York.

   DISCUSSION...A squall line has now become well developed in western
   Pennsylvania and is starting to accelerate eastward. This line of
   storms will pose a threat for damaging winds as it moves east.
   Isolated embedded mesovorticies are possible in the line, but the
   low-level shear vector remains mostly parallel to the line which
   should tamper a more widespread threat. The highest tornado
   potential will be along and near the warm front in northern
   Pennsylvania and southern New York. Currently, the strongest storm
   in the band is located along the warm front and is showing at least
   broad rotation. This storm and any that develop near it will likely
   pose the greatest tornado threat for the next few hours.
