The Weather Research and Forecasting Model is used within a semi-idealized modeling framework to investigate what modulates intensity, location, and cross-band asymmetry of precipitation in events such as this. Convection-allowing resolution and a sophisticated microphysical parameterization represent key LES processes while simplified initial and boundary conditions allow for controlled manipulation of model state-space and facilitate testing of specific hypotheses. Mesoscale experiments with horizontal grid resolutions of O(1000m) explore how background flow, lake geometry, terrain, and mesoscale convergence interact to control surface precipitation patterns. Low-level sublimation and preferential advection of hydrometeors by the cross-lake component of the geostrophic wind do not drive cross-band asymmetry. However, the interaction of cross-band asymmetry in the low-level wind field with lake-triggered convection may be a primary control on outflow dynamics and band asymmetry. Mesoscale experiments are supplemented by higher resolution simulations (O(250m)) to provide further insight on the interplay between sub-band convective features and mesoscale dynamics, and test the sensitivity of model results to horizontal resolution.
