..Southern New England/Mid Atlantic into the Southeast...
Multiple clusters of thunderstorms may be ongoing at the start of
the period Thursday morning from portions of the Mid Atlantic into
the Southeast. The location and severity of any such clusters is
quite uncertain at this point, but weak-to-moderate instability and
favorable deep-layer shear will support some wind/hail risk from
Thursday morning into at least the early afternoon. Large-scale
ascent is forecast to generally weaken Thursday afternoon, resulting
in a general decrease in storm coverage and intensity with time
along the surface boundary.
Further north into southern New England, strongly forced frontal
convection will be possible from late morning into the afternoon. If
sufficient low-level moistening occurs ahead of the front, some
damaging wind threat may evolve, but confidence is too low at this
time for any probabilities this far north.
