SUMMARY...Scattered storms will form this afternoon and a few could
contain enhanced gusty winds.
DISCUSSION...CU fields continue to increase with daytime heating
ahead of a cold front currently extending from western NJ into
central NC. A few deeper showers were already organized along the
front from eastern PA into NJ, with gusty winds noted along the

southeast VA into NC, with thunderstorms expected. While surface
winds are already strong in association with the front, any
thunderstorm downdrafts may augment wind speeds to near-severe
levels locally.
