Areas affected...portions of western into southern Pennsylvania
Concerning...Severe potential...Watch unlikely=20
Valid 262300Z - 270030Z
Probability of Watch Issuance...20 percent
SUMMARY...A few damaging gusts may occur over the next few hours.
The overall severe threat should remain isolated.
DISCUSSION...An MCS has been steadily organizing over western PA
over the past couple of hours. This MCS will continue to propagate east-southeastward amid a buoyant airmass, characterized by over
2000 J/kg MLCAPE. Furthermore, deep-layer westerly flow around the
upper ridge is promoting roughly 35 kts of effective speed shear,
oriented roughly perpendicular to the MCS leading-line. This may
foster continued organization of the MCS, with a few strong,
damaging wind gusts possible. The best chance for damaging gusts
will be with storm interactions between cells embedded in the MCS
with those in the free warm sector. However, severe gusts should
remain more sparse, so a Severe Thunderstorm Watch issuance is not
currently expected.
