It is well established that a nocturnal maximum in the diurnal cycle of summer rainfall occurs over a substantial portion of the Great Plains. This nocturnal rainfall maximum is associated with mesoscale convective systems that are, unfortunately, poorly represented in current weather and climate models. This presentation will discuss gaps in our understanding of nocturnal convective systems and present ongoing observational and modeling research on this topic, including recent work by current graduate students (B. Blake, M. Chasteen, K. Haghi, and S. Lillo). This research will be presented within the context of trying to explain why the Great Plains has a nocturnal maximum in rainfall. The presentation will conclude with some thoughts on how these ideas will be tested during the upcoming PECAN (Plains Elevated Convection At Night) project.
