SPC MD 1649MD 1649 CONCERNING SEVERE POTENTIAL...WATCH LIKELY FOR ORTIONS OF SOUTHERN VIRGINIA...WESTERN NORTH CAROLINA...FAR NORTHEAST TENNESSEE...SOUTHEASTERN WEST VIRGINIA 
Mesoscale Discussion 1649 NWS Storm Prediction Center Norman OK 1256 PM CDT Sat Jul 18 2026
Areas affected...ortions of southern Virginia...western North Carolina...far northeast Tennessee...southeastern West Virginia
Concerning...Severe potential...Watch likely
Valid 181756Z - 181900Z
Probability of Watch Issuance...80 percent
SUMMARY...Scattered to numerous thunderstorms will continue to increase in intensity this afternoon with a risk for damaging wind gusts. Trends are being monitored and a Severe Thunderstorm Watch is likely.
DISCUSSION...Thunderstorms continue to develop across the higher terrain of WV, NC and VA at 1755z, and also along a confluence zone extending from northern VA into western NC. Despite weak mid-level lapse rates, diurnal heating of a moist boundary layer has contributed to MLCAPE of 2000 to 3000 J/kg and low-level lapse rates of 8.5 to 9 deg/C. In the presence of minimal CINH, storms should continue to increase in coverage through the afternoon and move generally east. Shear in the cloud-bearing layer will average 20-25 kts across northern portions of the discussion area and 15-20 kts farther south, sufficient for updraft organization and a risk for damaging wind gusts.
Trends are being monitored and a Severe Thunderstorm Watch will be needed shortly.
