Mesoscale Discussion 1664 NWS Storm Prediction Center Norman OK 0918 PM CDT Tue Jul 16 2024 Areas affected...Portions of the Delmarva region Concerning...Severe Thunderstorm Watch 548... Valid 170218Z - 170345Z The severe weather threat for Severe Thunderstorm Watch 548 continues. SUMMARY...Damaging winds remain likely across eastern Maryland and into Delaware and southern New Jersey. WW 548 has been locally extended in time to address this potential. DISCUSSION...The line of storms that has recently crossed from eastern PA into northern and central NJ has shown a gradual weakening trend in IR imagery and lightning trends - likely the result of an undercutting outflow noted in regional radar imagery. As such, the severe threat for much of this line appears to be waning. However, further south across central to eastern MD, IR imagery continues to show intensification of convection to the west of Chesapeake Bay. The environment downstream of this activity appears to be only modestly capped based on a modified 00 UTC WAL sounding. While deep-layer wind shear remains marginal (around 25 knots based on the sounding), approximately 2000 J/kg MLCAPE remains in place, which will support the potential for additional intensification of somewhat organized clusters as storms move east into DE and southern NJ. Wind gusts between 45-55 mph appear most likely, but severe gusts will remain possible. WW 548 has been extended in time until 03 UTC when these storms should reach the coast. ..Moore.. 07/17/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...PHI...AKQ...LWX...
