Areas affected...portion of eastern Maryland and Virginia into
Delaware
Concerning...Severe Thunderstorm Watch 491...
Valid 302203Z - 302330Z
The severe weather threat for Severe Thunderstorm Watch 491
continues.
SUMMARY...The severe threat continues across Severe Thunderstorm
Watch 491. Strong to severe wind gusts (50-65 mph) remain the
primary threat with the stronger storms, though an instance of
marginally severe (around 1 inch diameter) hail is also possible.
DISCUSSION...Multicells and occasional transient supercells are in
progress across eastern MD into DE and eastern VA, which have shown
signs of intensification over the past couple of hours per latest
MRMS mosaic radar data. Though deep-layer shear is not as strong as
farther north (i.e. around 35 kts or so of bulk effective shear),
this amount of shear is more than adequate given 2500+ J/kg MLCAPE
in place. Regional radar data suggests these storms may be producing
wet downbursts, so strong to severe gusts remain possible through
the remainder of the afternoon, in additional to an instance or two
of marginally severe hail.
