If you see 2 or 3 closed 500mb contours SE of LI, really nothing else to be said-those have been our top snowfall producing setups. Inland wouldn't do quite as well but maybe close because of less wind (wind can hamper ratios by breaking up the flakes) and excellent moisture transport in the CCB. And we all know these love to put a NW fronto band in there somewhere like West Milford which always seems to get hammered in these.
I have about 32" now so if there's 12" from this that gets me to 44" which I'd consider quite good. My average here going back 30 years is probably about 35". Islip is 31" I think.
The storms aren’t officially chosen until next year for this winter I think but given the huge geographic area affected and BOS walking away with 23”, it’s a very high likelihood. It’s based on severity times number of people affected.
Doesn’t really matter to me what TV met X is forecasting right now, it’ll go up by this evening. 6-12” in the city is probably a good call at the moment, chance highest for 12”+ in Suffolk and coastal NJ.
Hopefully the Euro can finally jump on so we can start really talking bigger amounts (GFS is still probably excessive until other guidance jumps on. Other models are still further east/more strung out with the low).
Looks like the phase happens in a good spot and the 500mb low consolidates so we have a good enough mid level setup to generate lots of precip for most of us.
If the phase is cleaner and happens in a better spot/sooner, it’ll be better for us. We don’t want all these vorts ahead of the trough though, that’s what spawns these convective lows.
Well as great as the GFs was for us, we really need to see other guidance jump on to have any faith in that kind of outcome. A minor/moderate brush still very much on the table.
Mar 2017 was the second worst bust where I live other than Mar 2001, maybe even actually worse. 12”+ predicted, ended up 4” maybe all washed away by the end. Utterly horrendous. Other than that disaster 16-17 was actually a decent winter.
