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.
