Summary Episode 2 had larger cross-barrier bulk IWV flux and precipitation rates compared to Episode 1 The AR rode up and over the SBJ during both episodes, but there were structural differences: Episode 1 SBJ southeasterly at ~25-30 m/s, ~0.2-1.5 km MSL SBJ-AR interface extended to west edge of Central Valley and sloped SW-NE at 1-2 % Episode 2 SBJ southerly at ~20-25 m/s, ~0.3-2.5 km MSL SBJ-AR interface extended to west half of Central Valley and sloped SW-NE at 2-4 %
