February 13-14 potential snow storm

For whatever reason the most intense QPF stays on the east side of the storm. 6-8" for most at 10:1. QPF is over 0.75" for most and 1" plus east.

 

It'll correct itself soon anyway. What's great is that we are finally capturing a storm that 4 days out. The best part about this is that we aren't in the highest potential jackpot yet. This is starting to look a whole lot more interesting.

Still time to go on this-I wouldn't get excited for another 24 hours at least.

Inside the bench mark scares me

If the low's bombing out it will keep everything cold much closer to the low center than a weaker storm. I wouldn't be worried for NYC unless the low was over Montauk or so. I believe the 2/25/10 storm which bombed out and gave Central Park over 20" came ashore in Suffolk County. So did 12/30/00 which was snow into western Suffolk.

so as it stands now it looks like the coast mixes is that what your saying???

A dynamic storm would give most of the area heavy wet snow...Eastern LI is usually a tough call. Otherwise it's too early to talk about precipitation type and be exact about it.

Didn't it come ashore near Boston? The upper low just sat south of LI and captured the surface low. Once the surface low was moving wnw then west over mass LI changed to snow and we got dumped on as well...not the 20.9" by saw but 10+. The storm ended up looping back south then east right underneath LI before parking itself. Then it slowly dissipated as it drifted ene

Well this has certainly increased our appetites for the runs later on tonight, hasn't it.

 

I think the GGEM is still way too extreme, but the Euro suggests a strong consensus may be in the offing the next day or two.  The thing to me that gets my attention on the Euro, is the closing off of H5.  Euro is a bit later with it than a few of the other models, but it's suggestion can't be ignored at its face value.

A question for the mets?

Why does it seem that the heaviest QPF is on the east side of the low as compared to the western side?

I heard a met say it's convective feedback but I have no idea and I don't really wanna start with the whole convective feedback thing bc I am certainly not a pro and I would like to hear another met validate that before I even take it seriously.

Agreed, that's a pretty bad post. To be fair, though, the 40/70 benchmark has generally been discussed from NE's point of view, so a tightly wound benchmark system could well have a tight/unsavory precip cutoff in the NYC metro region.

This! Dynamic storms inside (not a coastal hugger though) the benchmark are always the best for our area.

It shouldn't. With this upper level evolution, if the storm takes a track inside the benchmark it is likely going to be decently wrapped up and the resulting lift and dynamics will be sufficient for snow away from the immediate coast (probably there too).

 

The one wild card still is the shortwave over the Great Lakes. Not only does that act as a kicker, but it totally kills the cyclones development on the NW side. No CCB, no dynamics, nothing interesting at all if that feature trends stronger or farther east.
