Mesoscale Discussion 1632 NWS Storm Prediction Center Norman OK 0241 PM CDT Mon Jul 15 2024 Areas affected...Southeast PA into MD/DC/northern VA Concerning...Severe potential...Watch unlikely Valid 151941Z - 152145Z Probability of Watch Issuance...20 percent SUMMARY...Isolated damaging wind is possible through late afternoon. DISCUSSION...Convection is gradually deepening this afternoon from south-central PA into northern VA, within an increasingly hot and well-mixed environment. While stronger large-scale ascent is displaced to the north of this region, continued heating/destabilization could support a gradual increase in storm coverage and intensity through the remainder of the afternoon. Deep-layer shear is generally modest and low-level flow is rather weak, but isolated damaging downburst winds will be possible with the stronger cells, as temperatures approach 100 F across the region. Northern portions of the MCD area could see another round of strong to locally severe storms this evening, as an MCV currently moving across western PA glances the region. ..Dean/Hart.. 07/15/2024 ...Please see www.spc.noaa.gov for graphic product...
