Areas affected...portions of southeast Pennsylvania and New Jersey
Concerning...Severe Thunderstorm Watch 489...
Valid 302141Z - 302315Z
The severe weather threat for Severe Thunderstorm Watch 489
continues.
SUMMARY...The severe threat continues across Severe Thunderstorm
Watch 489. Strong to locally severe wind gusts (50-65 mph) remain
the primary threat, though a couple instances of hail also cannot be
ruled out. The severe threat should gradually diminish as storms
move offshore.
DISCUSSION...Multiple organized thunderstorm clusters and short line
segments continue eastward across portions of the Mid Atlantic. Some
of the storms have a history of strong to severe wind gusts, and a
61 mph wind gust was recently measured in Camden County, NJ. These
storms are benefiting from an adequately unstable and sheared
airmass (i.e. 2000-3000 J/kg MLCAPE with 40-50 kts of effective bulk
shear). Regional VADs show that mainly speed shear is present via
elongated but nearly straight hodographs. As such, strong to severe
multicells and short line segments should continue eastward with a
strong gust/hail threat for at least a few more hours. Later this
evening, the severe threat should wane when storms move offshore
into the Atlantic.
