I have two questions, number one where is the cold air for tonight? I see basically 30 as the lowest temperature in ny state including western and northern parts. Second question is I don't ever remember getting a good snowfall in the 3-6 inch range with a northwest wind, do any of you remember a situation like that. Otherwise I'm psyched for our first snowfall for nyc and I will happy to observe from Brooklyn (home) and woodmere (work) and in between (belt parkway is sure to be a fun ride tomorrow if this snowfall happens.

 

I agree on the wind deal, I mentioned that earlier today I don't recall any event in particular where that occurred, a 330-360 wind yes but not 280-300...the temps and DPs will drop behind this boundary shortly, there are mid 20s dewpoints all over C PA...I think even the warmest areas will be 33/26 or so when the snow starts.

Our first snowfall was last night. I measured an inch, so that's pretty real to me

this is more than 3 hrs....come on

 

i'm talking about the heavy rates shown on the nam sim radar. They last no longer then 3-4 hrs…then will go back to lighter rates. He was calling for 8-10 amounts, this will not last that long to amount to that much...

 

 

 

plus you will be the one crying tomorrow when you see the back edge in baltimore

RGEM still isn't all that great, and has the heaviest amounts offshore. This is the kind of system where until I see the band getting ready to clock me on radar, there's room for doubt. The worst of this may still be mostly offshore, so we all need to watch carefully the trends in the morning. Especially north and west, this can still be a letdown.

All that I said was that if it verifies, however likely or unlikely, that someone could get 6-10". That's 1-3" hour rates for 3 to 4 hours, you do the math.

The RGEM is so insanely intense with the offshore band it appears to have subsidence to the north, its solution if it occurred would not be that bad an outcome for us if that megaband didnt form because you'd probably have a juicier more uniform area of snow

not really, I'll be happy with 1-2 on 12/10, it's early, anything now is a bonus

Yeah-it's going to come down to how the radar looks as it's approaching us. I hate (or love) these kinds of systems-either feast or famine.

Is the dry air eating the northern fringe of the megaband?
