December 2013 and January 2014 were among the snowiest months in recent memory for the lee-side of Lake Ontario, providing numerous intense long-fetch bands to study during the OWLeS field project. The Mobile Integrated Profiling System (MIPS) played an active role in sampling the internal structure of lake-effect snow bands during the OWLeS field campaign. The primary goal was to place the MIPS in the core of long-fetch bands on the east side of Lake Ontario. The MIPS sampled the core regions for extended time periods during eight IOPs, sampling a variety of radar structures quite similar to those of mesoscale convective systems and severe local storms but on smaller vertical scales. MIPS vertically pointing radar data commonly displayed Bounded Weak Echo Regions (BWERs) associated with updrafts, over-shooting tops, outflow boundaries, and cloud top Kelvin-Helmholtz waves. In one case, a snow squall developed a gust front and exhibited an overhanging weak echo region filled with updraft. Liquid water was commonly sampled in the convective core regions by the microwave profiling radiometer. Integrated liquid values up to 1 mm were common. This presentation will consist of an overview of profiling radar and thermodynamic retrievals from the UAH MIPS, as well as a discussion of the significance of these profiling observations when combined with data from scanning radars and aircraft facilities.
