ORH_wxman Posted January 30, 2021 Share Posted January 30, 2021 6 minutes ago, powderfreak said: Winter Hill for sure, ha ha. Without joking though, it has been interesting to see that there hasn't been a distinct ORH Hills enhancement look but more of a general speed convergence enhancement look as the moisture comes ashore in E.Mass. Like land friction or something causing a pile up of air as it comes off the ocean... the QPF plots almost look like a tide coming inland and then decreasing as you move away from the coast. All the global models have that look. Just strong convergence as the air piles up on land like a massive traffic jam, and that strong easterly flow has no where to go but upwards as there's a speed convergence going on in the low levels. Funny you point that out because that is a lot how Mar 2013 looked too. Saw this QPF Max over coastal E MA. To be fair, this firehose doesn’t look as prolific as that one but it’s still impressive.

I don't think you get as low QPF as some guidance suggests...I understand how banding works. It's the CTRV I am concerned about. Link to comment Share on other sites More sharing options...

Do you have the qpf maps saved from the Morch 2013 storm? I’d like to see what they printed out vs. what actually fell and where. Link to comment Share on other sites More sharing options...

It’s strengthening but not bombing out. So that sort of limits the magnitude of the lift. However, I’ve noticed that models will sometimes under forecast QPF in favored areas on deep layer easterly flow so we'll have to see how it looks as we get closer.

It’s always easier increase as you get closer than back off from a public reaction standpoint. Lol I remember when 8 to 14 was top end.

Saw this QPF Max over coastal E MA. To be fair, this firehose doesn’t look as prolific as that one but it’s still impressive. Yeah it's real even in the weaker/lighter solutions. Of course there's a larger scale deep layer easterly flow and mid-level lift spreading precip way west, but that's like E MA version of meso-scale precipitation genesis... almost like orographics. But the lift is from speed convergence of the flow coming ashore not terrain, and some ever so subtle veering of the flow from ESE to ENE under 850mb helping the lowest levels. It's just going to pile up air into E MA. That type of strong low level lift also should result in an area of sinking/subsidence air nearby... almost like a standing wave pattern for a time. Very similar to upslope when you get waves of lift/sink develop. Of course any mid-level deform banding can overcome that lower stuff too. Need to watch for some more acute minimums that may not be traditional. I'm very high confidence at this point in E. MA QPF max... even glancing blow and weaker, you will get that stronger lift there relative to elsewhere. The mechanism for convergence is pretty strong, sustained cross barrier flow with the shoreline. 2 Link to comment Share on other sites More sharing options...

I don't think that we will have the usual subby area away from the low level convergence associated w coastal front....the easterly flow should nix that. I think the subby will be brutal just west of where ever that ends...probably just west of ORH, since immunity to porkings are built into their climo....plus terrain should augment precip on easterly fetch. I feel like Steve to ORH best....Kev will be okay, but once you get west of him and lower in elevation...oof. Link to comment Share on other sites More sharing options...
