Areas affected...central and eastern Maryland into northern Virginia
Concerning...Severe Thunderstorm Watch 555...
Valid 101939Z - 102145Z
The severe weather threat for Severe Thunderstorm Watch 555
continues.
SUMMARY...The threat for damaging wind gusts may increase through
late afternoon as the ongoing storms encounter a more unstable air
mass.
DISCUSSION...Strong to potentially severe storms currently emerging
from the Blue Ridge Mountains are moving into a hotter and more
unstable air mass, characterized by MLCAPE of 2000-2500 J/kg and 0-3
km lapse rates of around 8 C/km. Moreover, The KLWX VWP is sampling strengthening westerly winds above 3.5 km AGL, which may aid in
storm organization. The extent of the damaging wind threat will be
dependent on the degree of cold-pool organization that can occur.
However, the more favorable parameter space with eastward extent
suggests that threat should increase through late afternoon.
