Scattered thunderstorms formed along a nearly stationary frontal boundary draped across the Mid-Atlantic. Increased dew points on the southern side of the front ranged from the mid 60s to lower 70s. These dew points along with temps in the upper 80s resulted in instability between 1500 and 2000 J/kg. The higher instability combined with deep layer shear values 30-40 knots led to the development of afternoon and evening scattered severe thunderstorms.
