Mesoscale Discussion 1674 NWS Storm Prediction Center Norman OK 0611 PM CDT Wed Jul 17 2024 Areas affected...Portions of southern New England and the Mid-Atlantic Concerning...Severe Thunderstorm Watch 552... Valid 172311Z - 180115Z The severe weather threat for Severe Thunderstorm Watch 552 continues. SUMMARY...A severe threat of damaging winds, and perhaps marginally severe hail, will continue across portions of southern New England and the Mid-Atlantic over the next 2-3 hours. Local watch extensions in time appear likely. DISCUSSION...Latest radar trends indicate two areas of damaging wind concerns across northern MA, and southward into far eastern PA. A small bowing segment, and a cluster of relatively robust updrafts are present within these regions. Although MLCIN should slowly begin to increase with the approach of sunset, surface observations across NJ ahead of the cluster suggest an undisturbed, buoyant air mass remains in place. Temperatures in the upper 80s to low 90s, along with dewpoints in the low 70s, is contributing to MLCAPE ~1000-1500 J/kg. Cell mergers occurring through this evening will have the opportunity to produce severe wind gusts with deepening cold pools. This may especially be true across portions of southern NJ where slightly stronger low-level flow exists. A bowing segment or two will also remain possible here. A local extension in time will likely be needed for portions of the watch. ..Barnes.. 07/17/2024 ...Please see www.spc.noaa.gov for graphic product...
