MCV Fuels Afternoon Wind Threat Across Carolina Piedmont — SevereWX

A remnant mesoscale convective vortex (MCV) over the central Appalachians is kicking off scattered thunderstorms from eastern Georgia into central and northwestern South Carolina. These storms are expected to organize into clusters and push east-southeast toward the Atlantic Coast through the evening.

Surface temperatures are baking into the low 90s°F, with dewpoints in the low-to-mid 70s°F fueling 2000-2500+ J/kg of MLCAPE. Steep low-level lapse rates, high precipitable water (over 2 inches), and 30-knot westerly mid-level flow are setting the stage for damaging downdrafts.

The prime risk zone lies across central South Carolina's Piedmont and Coastal Plain, where gusts could reach 55-70 mph—enough to down trees, power lines, and cause widespread outages. Southern North Carolina and far eastern Georgia may see scattered hits too.

SPC's Mesoscale Discussion 1585 flags a 60% chance of a Severe Thunderstorm Watch in the next 1-2 hours. Keep an eye on updates from NWS offices in CAE, CHS, GSP, RAH, ILM, and FFC.

Stay prepared: Monitor radar closely, secure outdoor items, and have a severe weather plan ready. Power outages are possible—charge devices now.
