Wow.. Oklahoma city!! HECS for them perhaps with this solution

I think they may get a bit shafted...the 500mb vort goes overhead which is odd to me...typically we would not see big snows there unless the 500 low was over N Texas...the later runs might shift the axis more into S KS.

NYC is snow through 51 hrs as per soundings. So, at least 2 inches of snow before the changeover.

And through 48 hours here is what has fallen

.25" is on NYC thru 51.

We are in lala land on the NAM and if you ask me on every other model at this range as well. Don't trust anything this far out this year, especially if you're located in a borderline location.

[MJO812]

You would be surprised how far a strong amplified low can go. It has happened before and it will happen again.

I would wait until tonight's runs to say that . I wouldn't be shocked to see this storm trend colder, especially if there is a strong high to the north.

NYC is snow through 51 hrs as per soundings. So, 2-3 inches of snow before the changeover.

And through 54 hours it is this

http://www.nco.ncep.noaa.gov/pmb/nwprod/analysis/namer/nam/12/images/nam_p48_054l.gif

But i do not know exactly how much of that happens between hours 51-54 when it is no longer snow. Seems to me it would be about 1-3" of snow

[SnowGoose69]

.25" is on NYC thru 51.

That is probably way underdone as well...I posted earlier that someone in MA/CT/NY/NJ will see double digits on Tuesday with that WAA shot.

NCEP experimental has 3 hour increments.

This is what's fallen thru hour 51.

.25"-.50" from NYC on west...

[Edge Weather]

Snow in NW NJ through 54 hrs as per soundings. So about 3-4 inches of snow for NW NJ before the changeover.

[TheTrials]

Tell ya one thing, the srefs and nam at 500 mb at 84 hours is pointing to good things for the next event.

[Guest stormchaser]

Oh i fully agree. Just looking at this objectively that's all. By the way werent the 12z runs today supposed to have recon data in them does anyone remember???

Thank you, appreciate the images

[ag3]

Our SW will be on the California coast for the 0z runs.

We can expect changes tonight.

Could be for the worse or better.

NAM starting to back you up.

[Edge Weather]

The snow chart from StormVista from the 12z run has almost all of Eastern PA at 8+ inches of snow except the extreme SE part of the state but includes areas only miles for Philly, and puts Warren and Sussex Counties in NJ at 4-8 inches.

You're all snow through 48 definitely, and you're probably eeking snow out of 54 as well, depending on how thick the warm nose at 850mb actually is. From 60-78 you're getting ZR, then plain rain. Verbatim on the NAM, I see 2-3" of wet snow, followed by 0.20" of ZR/IP/mess, then about 1" of plain rain. Not my idea of a good time.

I would think its still too early in the game for this yet

[NorEaster27]

I am getting pretty concerned about a rare freezing rain event in the city from this storm.

[chubbs]

Down here in phl area. The NAM has better front end snow compared to previous runs and still warms it enough to avoid a big ice storm

[Edge Weather]

I pretty much guarantee that is exactly what will happen.

thing to watch is if the high continues to strengthen in southeast canada and doesn't try to escape east - then thats a sign the low will try and redevelop and take the path of least resistance - plus climatology and the current set up favors this ....

[EasternLI]

Hmmm....Trending colder as we approach the event....sound familiar?? As is usual, much will depend on what happens with the HP.

[SnowGoose69]

I am getting pretty concerned about a rare freezing rain event in the city from this storm.

If the track shown ultimately happens I think they will go to rain since there could be southerly surface winds...I'd me more wary of either very big snows Tuesday or possibly significant freezing rain tuesday night if the initial WAA wave lasts a long time, long enough for the mid layers to really warm enough for ZR.

[Tiburon]

If the high escapes to the east, that initiates a maritime flow off the Atlantic--that's game over for everyone anywhere NEAR the cities.

[Edge Weather]

Please provide a link for this. Thanks.

NCEP experimental has 3 hour increments.

This is what's fallen thru hour 51.

.25"-.50" from NYC on west...

[chrisNJ]

ABE's sounding is right around 32 degrees toward the end of heavier portion of the 2nd event. It typically runs warm, so my guess is a "wicked" ice storm for the Lehigh Valley. Nothing like adding 3-5 inches Tuesday on top of the existing snowpack, then 0.5" of ice to encrust everything.

[Edge Weather]

Last night was supposed to have it. But I am not even sure they got planes there. They were not sure they would have planes available.

Oh i fully agree. Just looking at this objectively that's all. By the way werent the 12z runs today supposed to have recon data in them does anyone remember???

If the high escapes to the east then I agree but I am not sure that happens yet. We could be looking at an ageostropic north wind down the hudson which is what we saw in the sleet storm of 07.
