Probably biased in that regard with what to expect typically. Expand Yeah some of those scrapers can give PTSD in the interior. But in my long experience with central MA wx, I feel like as long as you are on the east slope of the ORH hills, higher elevation is going to equal more ice and more snow. The extra elevation outstrips any other variable when you are still on the east side of the spine. Once you go west of the spine far enough, things change since you start to lose the orographic enhancement on easterly and northeasterly flow.

Sure every time a place gets less precipitation there was more sinking air there than other areas, I guess ties all of them together regardless of where on a map they are… but we can do better than that basic premise in trying to dissect it meteorologically. They are absolutely a lower snowfall area but for a variety of factors, mid-level dry slots, warmth punching north, proximity to warm water, etc. But does it stand out more than neighboring areas in like SE Mass I guess is what I’m struggling with meteorologically. If it’s normal climo, there should be an easy answer. Link to comment Share on other sites More sharing options...

Expand I’ve seen the CCB slam SE areas including the Cape and this sort of mini slot develops in srn RI and into extreme SE CT. Maybe into areas west of New Bedford too. It’s definitely the dryslot in the mid levels, but sometimes the CCB from 850-700 can mask that off to the east. Sure maybe the prime DGZ dries out, but you have a firehose of moisture and small to medium sized flakes there. It doesn’t happen in every storm, but besides the March 2013 event, January 2005 and I remember January 2011 was an issue there too. It’s not due to downsloping, but perhaps maybe a standing wave that can develop if conditions favor. That’s what happened in March 2013 to the extreme. Big isentropic lift or upglide in ern areas. Sinking air to the point that sun sun was visible in RI, and then upglide again in CT. There was also a s/w in NY state that likely aided the totals near Kevin. 1 Link to comment Share on other sites More sharing options...

Expand Boom awesome, that’s the discussion detail I needed. It all makes sense. I think I was just balking at the standing wave being a climo normal pattern. Between the CCB and mid-level lift west also makes sense… you guys right on the coast are still pulling big QPF (even if low ratio) as it pivots on the coast… then the usual lighter/disjointed lift gap found in most storms between the CCB and the H6-H7 mid-level stuff. Looks like there’s a lot of reasons for GON-PVD-TAN line SE to have issues, ha. Cards stacked against them. I guess I never really looked at them as a “sinking air” on east flow type location.
