Mesoscale Discussion 1927 NWS Storm Prediction Center Norman OK 0104 PM CDT Tue Aug 11 2026 Areas affected...portions of the central Appalachians into the NC/VA Piedmont Concerning...Severe potential...Watch unlikely Valid 111804Z - 112000Z Probability of Watch Issuance...20 percent SUMMARY...The threat for occasional damaging wind gusts and perhaps isolated marginally severe hail will expand downstream over the next several hours. DISCUSSION...An ongoing MCS currently extending across portions of southern West Virginia has largely waned in intensity over the past 1-2 hours with modest cloud top warming noted via recent satellite imagery. Regardless, expectation is for this activity to continue south-southeastward through this afternoon along a surface buoyancy gradient. This threat is expected to remain generally isolated, however, owing to the more weakly sheared environment. Trends will continue to be monitored, but a downstream watch appears unlikely at this time.
