A warm front moved north through parts of the mid-Atlantic during the late morning and afternoon of March 3. A cold front followed closely behind it in association with strengthening low pressure moving through the eastern Great Lakes. An upper level shortwave was also approaching the area. The cold front moved rapidly through the region during the evening hours. Ahead of it, a weakly unstable but strongly forced and highly sheared environment existed. Widespread showers and some embedded thunder developed, and while lightning activity was limited the strength of the forcing and shear profiles allowed for some damaging wind gusts to occur.
