A strongly forced, narrow line of heavy showers raced eastward across the area during the late evening and early overnight hours. Despite limited instability and no lightning detected with the shallow convection, the presence of an intense wind field in excess of 50 knots just above the surface promoted corridors of wind damage with the passage of the line.
