A broken squall line of showers and thunderstorms produced scattered pockets of strong winds and a few tornadoes. The strongly forced squall line was accompanied by several transient meso-vortices within an environment of very strong low level wind shear. Very limited instability reduced the longevity of these meso-vortices. Dew points  in the upper 50's ahead of the line proved sufficient for a few tornadoes. A very strong low-level jet in excess of 80 knots supported the wind damage and tornado events along the line. Lightning was absent at times from the line. The line formed ahead of a strong cold front that trailed southward from a low pressure center passing north of the region. A very strong 500 mb shortwave pivoted east-northeast from the southern Plains, further enhancing the convection despite weak instability.
