...NO SEVERE THUNDERSTORM AREAS FORECAST...

...SUMMARY...
Isolated thunderstorms are possible from the Outer Banks into
southern New England late Tuesday into early Wednesday. Severe
thunderstorms are not expected.

...Synopsis...

An upper trough will pivot northeast from the Midwest toward the
Mid-Atlantic/Northeast on Tuesday. A prior cold frontal passage
across this region will result in limited boundary-layer moisture
despite increasing low-level south/southeasterly flow ahead of a
surface low. The exception will be along the immediate coast from
near the Outer Banks to southern New England Tuesday night into
early Wednesday. Surface-based instability will remain limited, but
weak elevated instability amid increasing large-scale ascent and
cooling aloft may be sufficient for isolated thunderstorms from the
Outer Banks (Tuesday afternoon) into southern New England (mainly
after 00z). Severe storms are not expected.
