As strengthening low pressure tracked through the Great Lakes on March 28, a strong cold front approached the mid-Atlantic coast. A narrow ribbon of modest instability developed ahead of the front. With strong wind fields in place and strong forcing from the cold front, a line of convection developed. The minimal instability caused this to be a low-topped convective line with little, though not zero, lightning. However, the strong forcing and wind fields caused the line to become a fairly prolific producer of straight line wind damage. A number of severe wind gusts were measured, with numerous reports of tree, utility, and some structural damage.
