0119 PM CST Wed Mar 05 2025
Areas affected...Northeastern West Virginia...northern
Virginia...western Pennsylvania
Concerning...Severe potential...Watch possible
Valid 051919Z - 052115Z
Probability of Watch Issuance...40 percent
SUMMARY...Damaging wind and hail threat may increase with
thunderstorm development this afternoon.
DISCUSSION...Diurnal heating along a secondary cold frontal boundary
located across West Virginia into western Pennsylvania has allowed
for convective development over the last 30-60 minutes. Temperatures
have warmed into the 60s ahead of this boundary, yielding around 500
J/kg of SBCAPE to develop. Looking at the mid-levels, a 500 mb
90-100 kt jet continues to move northward across the area,
supporting 0-6 km shear around 90-100 kts. CAM guidance suggests
further development is possible along the boundary through the
afternoon. Given strong shear profiles, some loosely organized cells
may pose a risk for damaging wind and hail. Convective trends will
be monitored over the next couple of hours for potential watch
issuance.
