...Parts of the northern Mid Atlantic...
Although there remains substantive spread within/among the various
model output, 30-50+ kt southerly flow in the 850-700 mb layer may
linger into the day Thursday across much of the northern Mid
Atlantic region, generally coincident with the corridor of
seasonably moist boundary-layer air. Although lower/mid
tropospheric lapse rates are forecast to remain weak, weak to
moderate CAPE may still develop and contribute to scattered
thunderstorm activity with daytime heating. In the presence of
moderate to strong shear in the lower to mid-levels, the environment
may become conducive to organizing lines or clusters with the
potential to produce locally damaging wind gusts. Latest guidance
appears increasingly suggestive that hodographs could become
characterized by substantial clockwise-curvature in low levels,
particularly across parts of eastern Pennsylvania and New Jersey
into south central and southeastern New York state, which may
support a risk for a couple of tornadoes.
