Thunderstorms Monday across the Southeast
As an area of low pressure and the associated fronts slowly move eastward on Monday, severe thunderstorms may develop from eastern Georgia through the coastal Carolinas. Although ongoing showers and thunderstorms, along with cloud cover, will limit instability, a few strong to severe thunderstorms may develop. Large hail, damaging winds, and tornadoes will all be potential hazards with these storms. As these storms move eastward into the night time hours, damaging winds and isolated tornadoes will become the primary concerns.
