DISCUSSION...Isolated strong storms across VA have gradually intensified this evening, with short-term guidance suggesting a continued increase in storm coverage with time. While thermodynamic profiles are not particularly favorable (with weak lapse rates and rather cool surface temperatures), seasonably strong northwesterly mid/upper-level flow (as noted on the 00Z RNK sounding) associated with a mid/upper trough over the eastern CONUS will provide sufficient deep-layer shear for organized storm structures. Relatively organized multicells and perhaps a couple of marginal supercells may evolve with time across the region. With marginal thermodynamic profiles and the onset of nocturnal cooling, storms may struggle to achieve severe intensity. However, any organized cells or clusters could pose a threat of locally damaging wind through the evening, while a brief tornado and small to near-severe hail cannot be ruled out with any persistent supercell. ..Dean/Smith.. 07/27/2026 ...Please see www.spc.noaa.gov for graphic product...
