Areas affected...Mid-Atlantic States

Concerning...Severe Thunderstorm Watch 481...

Valid 011902Z - 012100Z

The severe weather threat for Severe Thunderstorm Watch 481
continues.

SUMMARY...Multiple clusters spreading across the Piedmont to Coastal
Plain should produce swaths of damaging winds as activity reaches
Chesapeake/Delaware Bays and the adjacent Mid-Atlantic Coast.

DISCUSSION...Scattered to widespread thunderstorms are ongoing with
multiple consolidating clusters over central to southeast PA and
northern VA. The northwesternmost of these has maintained coherent
but sub-severe outflow that should spell the end of severe potential
in its wake. With potential for cold pool intensification, this
cluster may accelerate and merge into the leading clusters. This
would consequently increase damaging wind potential across the DE to
Chesapeake Bay vicinity. Low to mid 90s surface temperatures, away
from any immediate marine influence, are common in these regions,
supporting peak MLCAPE of 2000-2500 J/kg ahead of the clusters.
Strong to localized severe gust potential is expected to peak in the
next 2-4 hours.
