Observations of the surface structure of supercell thunderstorms are presented utilizing data collected with a recently developed, rapidly-deployable surface observing system dubbed StickNet. Boundaries within the supercell are diagnosed for five deployments during the Multiple Observations of Boundaries in the Local Storm Environment (MOBILE) field campaign of 2007. Analysis reveals that a weak thermodynamic boundary suggestive of storm-modified inflow air can exist across the forward-flank reflectivity gradient of the supercell in both tornadic and nontornadic storms.
