On the afternoon of Oct 4 a strong system moving through the northern plains brought a cold front to the region. An unstable air mass was able to move into the area ahead of the system setting the stage for thunderstorms. As the main trough moved through the plains in continued to deepen allowing for strong winds. The combination of wind shear and instability lead to an outbreak of severe thunderstorms in northeast KS as the cold front progressed eastward. Damaging winds were the primary outcome from this event.
