Wider weather episode

Strong low pressure tracked through southern Canada on April 21. A warm front associated with the low moved through the mid-Atlantic during the morning hours, with a strong and fast moving cold front following closely behind for the afternoon. This was an unseasonably strong cold front which marked the leading edge of a much colder than average air mass moving into the region behind it. A strongly forced and highly sheared environment existed ahead of the front. Widespread morning cloudiness and rain showers limited instability, but a brief window of clearing allowed for heating and destabilization to occur. A severe squall line developed, producing considerable wind damage over eastern portions of the mid-Atlantic. A weak tornado also occurred along the New Jersey coast.
