...THERE IS A MARGINAL RISK OF SEVERE THUNDERSTORMS ACROSS PARTS OF
THE MID ATLANTIC...

...SUMMARY...
Thunderstorms capable of locally gusty and damaging winds are
possible across parts of the Mid Atlantic on Wednesday.

...Synopsis...
A rather amplified upper-level pattern is expected across much of
the CONUS on Wednesday, as a trough deepens from the Great Lakes
into the Mid Atlantic and Northeast, a ridge remains dominant across
the High Plains and Intermountain West, and a mid/upper-level low
moves northward just off of the Pacific Northwest coast. A cold
front is forecast to move slowly southward across parts of the OH
Valley, Northeast, and Mid Atlantic, while another cold front moves
southward across the northern Plains and upper Midwest.

...Mid Atlantic...
Scattered thunderstorm development is expected across a broad region
from the OH/TN Valleys into the Mid Atlantic and Carolinas Wednesday
afternoon, within a moist environment along and south of the cold
front. Deep-layer shear will be weak to negligible across the region
due to very weak flow aloft, so storm organization is expected to be
limited. However, some threat for locally damaging wind gusts may
evolve across parts of the Mid Atlantic, where stronger
heating/destabilization is currently expected, and weakly difluent
upper-level flow may enhance storm coverage. Weak westerly flow in
the 850-500 mb layer may be sufficient to support one or more
eastward-propagating outflow-driven clusters, in addition to a
threat of isolated wet microbursts.

...Interior Northwest...
The eastern fringe of stronger midlevel flow associated with the
upper low offshore of the Pacific Northwest will overspread parts of
northeast WA/southeast OR and adjacent northern ID on Wednesday.
Some uncertainty remains regarding the degree of destabilization and
storm coverage across the area, which precludes the inclusion of
severe probabilities at this time, but some potential for high-based
storms capable of locally strong/severe gusts may evolve Wednesday
afternoon and evening.
