Virginia Supercell, Line Storms Prime Large Hail, Winds for North Carolina — SevereWX
Virginia Storms Organize for Severe Push into North Carolina
The Storm Prediction Center highlights a growing severe weather setup across northern Virginia into north-central North Carolina through late afternoon and early evening. A supercell churning in north-central Virginia is tracking southeast amid decent deep-layer shear, priming it for large hail up to 2.5 inches and damaging winds. Low-level flow remains weak, focusing threats on hail cores and gusts.
Southward, a mixed-mode thunderstorm cluster along a surface boundary in south-central Virginia is shifting southeast into a juicy environment. Daytime heating has spiked temps into the mid-90s°F with steep low-level lapse rates and moderate-to-strong instability. Even as shear weakens south, cold pool development could amp up wind damage potential to 60 mph as the line advances.
SPC pegs the odds of a Severe Thunderstorm Watch at 80%, covering this stretch from roughly the DC suburbs through central Virginia and into the Triangle area of NC. Peak threats: 1.50-2.50 inch hail and 60 mph gusts.
Check the SPC Mesoscale Discussion graphic for the latest outline. Storms could intensify downstream, so monitor radar closely.
Stay prepared: Secure outdoor items, seek shelter if storms approach, and have multiple alert sources ready—NWS warnings, apps, or NOAA radio—for quick action on hail or wind hits.
