well it looks like the bronx gets it good for the 2nd time in a week..most snow maps currently have us at 4-7 inches across the borough more as you head immediately just north and west of the cross bronx(i95),not bad at all id say considering the models are now starting to limit plain rain until the end of precip. :thumbsup:

How so? South west being good or bad? I'd imagine south west means less of a warm up?

The sw winds at the surface would be a fetch over land rather than from the ocean and more importantly not from the Gulf Stream region. The SW trajectory would mean the wind not only has more friction imposed on it from topography, but it likewise has to transverse cold land and only the shallow water close to the island. Therefore NYC and LI would likely remain a couple degrees cooler. Combine that with the current Arctic cold in the area and temperatures will be that much harder to rise to and above freezing.

Nice.

Agree, if that is indeed the case in the end. Also, in my view, ocean temps are not cold enough to prevent the changeover. However, I do think they are cold enough to act as more of a buffer then they would in say DEC. At least as far as surface temps go.

It is my understanding that the ocean is above normal warm, to the point that it is affecting migratory fish patterns.

Ehhh what? Near shore waters the ones we care about in this case are about as cold as they have been in 20 years at any point. Very close to shore as in a couple miles they are in the low 30s (remember salt water freezes at 28)

10-50 miles out mid to upper 30s and all the way to the north Gulf Stream wall (150+ miles out) upper 30s to low 40s

This is going to have a huge impact on what happens on the south shore of the western island.

Uptons map would work great for a November/December storm. Not a once every 20 year cold ocean storm. Not sure what they are thinking lately. Ups down and downs up out there

A friend and I were discussing Upton recently and surmising what may be going on and he came up with what I think is a pretty good explaination. Going through the atmospheric sciences classes, we both found that they are beginning to focus very heavily on computer programming. Undergrad focused more on this than the forecasting side we found, though the science side was also heavily weighed upon as well. Additionally, Upton now requires a master's degree to work for them as a forecaster and consequently the canidates become further indoctrinated with computer programming skills. Now while the program trains you very proficiently in both the science and computer programming aspects, they do not teach how to apply this knowledge to forecasting anymore. We were being taught to find the problems within the algorithms on the computer models, however, not to apply the science of what the computer models are doing incorrectly. We both believe that this is where Upton is having issues.

Agreed. But just today I read a fisheries scientist talking about how much warmer the Atlantic is, and it is  likely causing fluke populations to drift further north. I guess he means over an entire season.

Interesting discussion. Can be seen in other fields as well. I remember a friend whose doc told him his labs and scans were fine, but he looked bad and he might be in kidney failure. He was. That comes from experience.

Very good analogy. And very applicable here. When experience tells you early in the season it's very hard to snow on the south shore and you see a marginal setup but a forecasts are for snow you just know it will not. This is the inverse. Very cold water with a SW flow and 850s fairly uniform across the region early in the game why does it snow in NYC and not western Long Island. I say it does and I'm 99% certain

He means the waters offs shore closer to the gulf stream...there a lot warmer and I to didn't believe it till I saw a map
