The tornadoes occurred in an atmosphere that was highly sheared, with large values of helicity, but only modest values of CAPE - a favored environment for tropical cyclone tornado outbreaks. In addition the outbreak area was in the northeast quadrant of the advancing remnant low pressure area, enhancing the potential for tornado development. Like many documented tropical cyclone tornado outbreaks, this event was characterized by several mini supercells, small shallow mesocyclones, and a surface boundary which helped increase horizontal vorticity and strengthen the low-level mesocyclones.
The paper will review this tornado outbreak, with an assessment of its synoptic and mesoscale environment within the scope of current and historical research of tornadic events associated with tropical cyclones. The presence of a mid-level dry air intrusion will also be examined, with a determination of whether it played a significant role in the magnitude and severity of the outbreak.
