Areas affected...portions of eastern Maryland and Pennsylvania into
Delaware...western New Jersey...and eastern New York

Concerning...Tornado Watch 605...

Valid 072101Z - 072230Z

The severe weather threat for Tornado Watch 605 continues.

SUMMARY...The severe threat continues across Tornado Watch 605. All
severe hazards remain possible. The severe threat may also develop
farther north into eastern NY, where a new WW issuance may be
needed.

DISCUSSION...Supercell structures across northeast PA, and a QLCS
along the PA/MD/VA border area, continue to approach the Hudson
Valley (Tornado Watch 605 area). A few instances of low-level
rotation have occurred with the northeast PA storms, with continuous
reports of damaging gusts being received with the aforementioned
QLCS. Over the Hudson Valley, an adequate buoyancy/vertical shear
parameter space exists to promote a continued severe threat with the
ongoing storms as they approach the Delaware River. Damaging gusts
appear to be the main threat given increasing linear storm modes.
However, a couple of tornadoes may still occur with persistent
supercells and/or QLCS circulations. Adequate buoyancy has also
materialized farther north into east-central NY, where approaching
storms are also increasing in number and intensity. Pending
convective trends, a WW issuance may be needed across portions of
the Upper Hudson Valley.
