Areas affected...eastern NC into northeast SC

Concerning...Severe Thunderstorm Watch 540...

Valid 232240Z - 232345Z

The severe weather threat for Severe Thunderstorm Watch 540
continues.

SUMMARY...Overall severe threat appears to be slowly diminishing.
However, a few strong gusts are still possible with the strongest
cells. The severe threat will come to an end as convection moves
offshore in the next couple of hours.

DISCUSSION...A line of strong storms ahead of a surface cold front
will continue to shift east/northeast across the NC/SC coastal
vicinity the next 1-2 hours. Some strong gusts are still possible as
the downstream airmass remains unstable. However, low-level lapse
rates are generally poor and stronger downdraft winds will mainly be
driven by water loading with a corridor of PW values over 2 inches
along the coast. Furthermore, effective shear weakens with eastward
extent. Recently, radar reflectivity loops have indicated outflow
surging ahead of the line across portions of NC, indicating
convection could be struggling to maintain organization with
decreasing shear, and storms behind the outflow have indeed weakened
some. Overall this could be signaling a decrease in severe potential
as convection approaches the coast. Nevertheless, a few strong gusts
are still possible with most intense cells over the next 1-2 hours
as storms move offshore.
