Areas affected...Parts of the Mid Atlantic
Concerning...Severe Thunderstorm Watch 335...
Valid 142222Z - 150015Z
The severe weather threat for Severe Thunderstorm Watch 335
continues.
SUMMARY...The damaging-wind threat may increase into this evening.
Additional watch issuance is probable.
DISCUSSION...Widely scattered strong storms are ongoing early this
evening from south-central VA into western MD and eastern PA.
Moderate buoyancy resides across parts of VA/MD, within a very
warm/moist environment, while continued low-level moisture transport
may allow for some additional destabilization with time into NJ and
eastern PA. Effective shear of 30-40 kt will continue to support
potential for organized convection, and an increase in storm
coverage is expected as a midlevel shortwave trough approaches the
region from the Ohio Valley.
Ongoing semi-discrete convection will pose a threat of damaging wind
and perhaps marginal hail, and a brief tornado cannot be ruled out.
The anticipated increase in storm coverage could lead to modest
upscale growth and one or more localized swaths of damaging wind
through the evening. Additional watch issuance is probable to the
northeast of WW 335 in response to these threats.
