   Concerning...Tornado Watch 529...

   Valid 282053Z - 282300Z

   The severe weather threat for Tornado Watch 529 continues.

   SUMMARY...A consolidating line of storms will continue to pose a
   risk of damaging/severe winds, and perhaps some tornado threat,
   across the Mid-Atlantic region over the next few hours.

   DISCUSSION...Latest radar imagery from KLWX and KCCX show the
   continued consolidation of a line of thunderstorms across
   south-central PA into northern VA. Although most wind reports have
   remained in the 35-45 mph range, several instances of wind damage
   have been noted, and KLWX velocity imagery depicts at least a couple
   of embedded swaths of stronger winds. Downstream, temperatures have
   warmed into the 80s, which is supporting a pocket of MLCAPE near
   1500 J/kg. Additionally, the KLWX VWP is sampling a nearly straight
   hodograph featuring around 45 knots of 0-6 km BWD. This
   thermodynamic/kinematic environment should be favorable for
   continued organization of the line and an attendant threat for
   damaging/severe winds as it approaches the I-95 corridor over the
   next 1-2 hours. While severe winds remain the primary concern,
   adequate low-level wind shear orthogonal to the developing line may
   support a few embedded circulations.
