The goal of this study is to highlight interesting cases obtained from the PX-1000, and examine polarimetric characteristics of MCSs at X band. During the 25 June 2015 IOP, the PX-1000 observed both leading and trailing stratiform precipitation and comparative analyses of these stratiform regions will be presented. An intense rear-inflow jet was also observed with varying near-surface wind profiles. The second MCS case focuses on a mature leading line, trailing stratiform (LLTS) during which intense near-surface winds were observed. Polarimetric characteristics of an intense convective band behind the primary convective line and a robust trailing stratiform region will be analyzed from the 6 July 2015 IOP. The analyses will use velocity-azimuth display and quasi-vertical profiles in conjunction with PPIs and RHIs to examine the kinematic and microphysical characteristics of these cases.
