February 9th Possible Inverted Trough

9 hours of snow in the NNJ and NYC Metro area - this is 10:1 ratios - comes in at night giving us 12-15:1 ratios- here is a bookend surprise to Friday



This LP crawls from AC to the BM - RGEM, NAM have it in meoscale - HI TRES NAM, RGEM - this woudl be wave 3 comeback in a huge way for many who got skunked by today's Junmo part duece.

some places will get some light snow tonight as precip rotates back over us then tomorrow late afternoon thru wens morning moderate snow for most as a coastal develops south of nyc 2-4" at 10-1 ratio's

Yes skinns I have a warning with 4to8 I don't believe t

Mt Holly has almost all of ocean county south 5-6 inches....good storm

Yes jake your right just saw it I guess they think Cnj is going to get the goods

@ Skins and those who may seem confused - what Al and I are discussing is the possibility of another coastal popping up along the Jersey coast Tuesday night into Wed this is NOT the IVT at this time. The ivt is going to be s of us cnmj to philly and south to dc

Yes, a lot of recent guidance shows a decent storm for CNJ

yes they are - you could get two mecs back to back!!!

Here is my first call for tomorrow:



While this is only based on data through today's 12z runs, I would not be surprised if I have to add a little bit to the northern/western extent of my 3-6" zone, and maybe add a 6-9"/"locally up to 8/9" area based on what I have seen so far today. While there is still a broad consensus that the IVT stays largely south of NYC, some of the modeling is starting to hint that it may end up further north than it has been progged to, and instead of only targeting Baltimore/D.C. and possibly Philly, it looks to me like it has crawled northward to now also include central NJ and the eastern half of LI. This idea has support to me in looking at the mid-levels, as what used to be a shortwave begins to become sheared out as it rounds the base of the trough. Through PVA, it looks to hold together long enough to possibly bring some moderate snows further north. This also translates to H7, where a local closed-low beneath this shortwave/PVA may aid in enhancing omega for a  period of time tomorrow midday and afternoon. Another concern of mine is that these same forcing mechanisms may be just enough to develop a relatively weak coastal system right along the coast, and almost as an extension of the IVT, when combined with the large degree of baroclinic instability between the warm Atlantic and incoming Arctic airmass. While it may be weak and the forcing mechanisms may be declining in strength, this developing surface low could throw more moisture back over its northwestern side, mainly in the form of bands with some stratiform precipitation. This will be a key feature to watch in the very short-range guidance, as well as how the mid-level energy allows the levels beneath to evolve. Just my thoughts.

GOOD CALL RB AND LOOK AT THE FOLLOW UP WAVE - I AM GOING TO START A NEW THREAD FOR THIS

i was looking at the future cast it does not look good espe for nyc and east

I am going to look at this in more detail when I get home but I think the dynamics at play are in fact due to the IVT. The axis simply shifts.

I want everyone to be very clear on this. IVT has HUGE bust or BOOm potential. I am willing to bet you will get folks down in the DC area crying because they busted because it either never materilaized, or set up different than what was modeled. This is the nature of an IVT. I NEVER trust the models verbatim to where they set up and trust even less so the amt of QPF they spit out over the areas they do show it set up. What appears to be a 4-6" event under the IVT can turn into 12-14" in a heart beat. Not saying that happens here but it has and will happen again.

We are all in the game still for this event.

 tx  We are not too far from each other I am in Hazlet...

FOLKS,

NAM, RGEM are calling for a coastal to pop up off teh jersey shore and travel ene to the benchmark at this time. Al is the first to catch this and I give him credit here.

18ZRgem map of liquid

The map above is at 10:1 ratio but this bad boy is coming at night and it woudl be a 12 to 15:1 ratio type storm.

I'm not worried about the ivt more about the coastal.

snj is mostly rain for this one since the coastal is forming right over your heads



rain

that is about .5 -.7 " of liquid if it serves on the rgem. nice little storm

12Z Metogram precip charts

better view of rgem



falls at night so should be better for stickage

0z runs are big tonight for this

rgem still snowing...
