This study analyzed the electrical, microphysical, and kinematic characteristics of a developing mesoscale convective system (MCS) observed in Oklahoma on 6 June 2012 during the Deep Convective Clouds and Chemistry (DC3) field experiment. The northern portion of the MCS was within range of the Oklahoma Lightning Mapping Array and three mobile radars providing dual-Doppler and polarimetric radar observations between 2048 – 2300 UTC. Gridded flash parameters (including flash extent density and average flash size), the dual-Doppler wind field, and the microphysical results of both a C-band hydrometeor classification scheme and a diabatic Lagrangian analysis depict the co-evolution of lightning, microphysics, and kinematics in three dimensions in both the convective line and stratiform regions of the MCS.
