   Areas affected...portions of eastern Maryland into Delaware

   Concerning...Tornado Watch 529...

   Valid 282227Z - 282330Z

   The severe weather threat for Tornado Watch 529 continues.

   SUMMARY...A locally higher tornado threat may materialize in the
   next 1-2 hours.

   DISCUSSION...Multiple supercells have matured ahead of an
   approaching MCS. These supercells are intensifying within a very
   moist low-level environment, where 2000+ J/kg MLCAPE is present, and
   where the DOX VAD shows a modestly sized/curved low-level hodograph
   and over 200 m2/s2 0-3 km SRH. In addition to showing a modest
   increase in low-level rotation within the supercells, the absorption
   of these supercells into the MCS may promote conditionally favorable
   storm interactions which may briefly heighten the tornado threat.
   The best chance for a tornado will likely be within the next 2
   hours.
