An area of low pressure moving out of the Southeast began to explosively intensify as it moved over the mid-Atlantic. On the morning of February 7, the eastern mid-Atlantic was briefly within the warm sector of the deepening low. An environment of extreme wind fields was present, and temperatures and dew points rose enough for sufficient instability to develop to sustain convection. A line of low topped but intense convection developed, and despite producing little thunder and lightning it produced a long swath of wind damage over the mid-Atlantic, along with a few tornadoes between Virginia and Maryland.
