-parallel bands produced by horizontal roll convection (e.g., Kelly 1982 , 1984 , 1986 ; Kristovich 1993 ; Laird and Kristovich 2004 ). Hybrid events that have characteristics of LLAP bands and broad coverage events, typically with an apparent connection to a LLAP band from an upstream lake (e.g., Lake Huron or Georgian Bay). This morphological regime is synonymous with the hybrid classification of Niziol et al. (1995) , who referred to LLAP band and broad-coverage events as type I and II, respectively

-disaggregated precipitation is generally larger than the ETI observations, consistent with undercatch. From 0300 to 0600 UTC, the NR ETI erroneously reported no LPE despite an increase in snow depth. c. Lake-effect mode classification The overall mode of lake-effect precipitation during IOP2b fluctuated between broad coverage and intense LLAP bands, with broad coverage sometimes occurring concurrently with a LLAP band (i.e., LLAP with broad coverage). Following Veals and Steenburgh (2015) , we use 0.5° radar

. As decreases, the blocking and deceleration decrease, with unblocked flow for (e.g., Pierrehumbert and Wyman 1985 ; Smolarkiewicz and Rotunno 1989 ; Smith 1989 ; Durran 1990 ; Galewsky 2008 ). This relationship assumes dry flow, however. For saturated flows, the moist Brunt–Väisälä frequency can be used to characterize stability (e.g., Fraser et al. 1973 ; Barcilon et al. 1979 ; Durran and Klemp 1982 ; Jiang 2003 ). The flow regime has a profound influence on the distribution of
