Mesoscale Discussion 2043 NWS Storm Prediction Center Norman OK 1227 PM CDT Sat Sep 06 2025 Areas affected...Parts of central/eastern VA. southern MD...and northern NC Concerning...Severe potential...Watch unlikely Valid 061727Z - 061930Z Probability of Watch Issuance...20 percent SUMMARY...The area is being monitored for increasing severe-thunderstorm potential this afternoon. The stronger storms will be capable of producing damaging winds and isolated severe hail. A watch is not currently expected, though trends are being monitored. DISCUSSION...Boundary-layer cumulus is becoming increasingly agitated along a prefrontal trough extending from central/eastern VA into northern NC, and initial signs of convective initiation are evident. Continued diurnal heating/destabilization amid lower 70s dewpoints should support isolated to widely scattered thunderstorm development over the next few hours. Despite poor midlevel lapse rates, the warm/moist PBL will still yield moderate surface-based buoyancy, which will favor gradual updraft intensification. Additionally, around 35 kt of effective shear may promote loosely organized cells/clusters, with a risk of locally damaging wind gusts and isolated/sporadic marginally severe hail. Current thinking is that the severe threat will be too localized/marginal for a watch, though trends are being monitored. ..Weinman/Hart.. 09/06/2025 ...Please see www.spc.noaa.gov for graphic product...
