A slight severe risk was draped across much of the CWA due to a surface convergent boundary over western counties with an approaching cold front from the north. Supercell thunderstorms developed along the convergent boundary during the late afternoon before forming into a complex line of storms along the front that lasted into the overnight hours. There was ample instability with CAPE over 2000J/kg coupled with decent shear up to 30KT and moisture influx due to the more saturated and unstable southeast low level flow. Early on with the supercells, funnel clouds and large hail were the main threats. Once the line developed and pushed south and east, damaging winds and hail became the hazards with many reports that verified a number of the warnings that were issued.
