March 13-14th Nor'easter Threat

The lack of clarity surrounding the evolution of this storm is astounding. The most important period of this entire evolution occurs around 36-48 hours and models are still all over the damn place with it. The NAM gets close to even giving the mid Atlantic some snow. Go figure.

Pretty surprising to see so many changes from run to run on every model. Just goes to show you how delicate this setup is.

The southern stream is too strong and ends up pushing it much further east with less phasing. We’ll see about that. 

It's the NAM so I wouldn't be concerned. But what looks likely is that we have this inverted trough feature as the storm comes in that might be spinning up this western low appendage, and it screws people near the coast because that inverted trough brings in 40 degree maritime air on strong easterly wind. Another reason we want this offshore low to develop quickly, so the flow can back around to offshore and dynamics can overcome the crap initial airmass. That inverted trough and the too slow development of the low are the main factors that are ruining it near the coast.

We looking at the same euro run?

What Euro run am I looking at? The Euro shows rain for most of the storm (monday into monday night), and then  a little back end snow on tuesday. That map shows a few inches for the NYC area, and when you take ratios into account it would be less than that. An inch or two of slop. Every model shows most of this storm being rain for the NYC area. Hopefully we'll see some changes, but right now it isn't looking great.

Not our storm for sure

Maybe for most of NJ, NYC and LI.  Our northern posters would get smacked if that run were correct.  That's what he's taking issue with.
