Areas affected...eastern NC and southern VA

Concerning...Tornado Watch 688...

Valid 271633Z - 271830Z

The severe weather threat for Tornado Watch 688 continues.

SUMMARY...A few brief tornadoes remain possible through the rest of
the afternoon as a weakening band of showers with embedded
thunderstorms moves across parts of eastern North Carolina and
southern Virginia.

DISCUSSION...Despite numerous low-level mesocyclones during the late
morning to midday, tornadogenesis has largely appeared elusive
within a persistent band of convection from the central NC/VA border
area southward into coastal far southern NC. One strong meso with
the deepest updraft last hour may have briefly produced in southern
NC per an ILM LSR. Low-level winds have subsided across the coastal
plain via LTX VWP data, but do remain sufficient for a brief tornado
threat amid 74-78 F surface dew points and temperatures in the low
80s. Farther north, low-level hodographs remain rather enlarged, but
will shrink throughout the afternoon. Morning CAM guidance suggest a
breakup to the convective band should occur, which will yield a more
cellular mode. This would favor potential for a few tornadoes, but
should be tempered by the otherwise diminishing shear/ascent
environment.
