   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.
