Your going to want to see models deepen this into upper 980’s or at least lower 990’s by 18z Sunday if you want good CCB and Banding , it’s certainly not a foregone conclusion at this point , esp out west
We have seen some runs do thus particularly at noon time and evening and 0z runs not have nearly the CCB of earlier (except for Boston / Se mass ) . I think that is the biggest wildcard and it was back and forth with this idea for last 36 hours . 0z nam was sort of an anomaly as it had a quick violent burst for S SNE wee hours Sunday am and not much part two except S shore and cape
