Mount Holly, NJ CWA - Starting to See Development

Over the last 13 minutes, we are starting to see development in the Mt. Holly CWA.  At 1918Z, there were a few showers but at that time, no lightning present.

Just a short 13 minutes later (1931Z), two storms have developed in the unstable air mass and are producing a decent number of GLM Flashes.

Unfortunately, the existing cloud cover has limited the use of the Derived Stability products today.
1917Z - GOES-16 Derived Parameters (UL - CAPE, UR - LI, LL - PWAT, LR - Sandwich)
Looking at the SPC Meso page, there is decent MLCAPE and Effective Bulk Shear over the CWA.
