What’s intriguing to me is that around 15-18z as LLJ cranks, lapse rates steepen in lower levels. So although max LLJ lifts out, the low is so wrapped up that slight CAA mixes to and above 925 perhaps briefly.
But Ray to your point, sometimes the CCB cranks with the 850 jet and while not as intense as mid level deffy....there can be a subby area as you stated. I guess I wouldn't blame the CJ directly...but I know what you mean.
Ray calls that area from about me down to Duxbury and just inland an ocean effect circle jerk. Usually if that happens, he’s sucking exhaust because the low is too far SE to really shove moisture towards his way.
I got semi porked jn the Feb CJ where I was. I think I had like 16” or so, while 8 miles east had 30. Another one of those “will I ever see a two foot storm…” questions.
