CMC did bring back the miller b though. Just a bit late.

If ur looking for a storm to come out of the northern branch and blowup , you are goin to need way more buckling of the trough. You would want to see the system running off the delmarva at worst , hatteras would b better

A storm is not goin to come to the jersey shore , stop and make a left hand turn. With the flow currently progged So if that's the path then you will see all the deepening to far to your east.

It's likely that we are cold and dry during this period but then there are big differences between the Euro and GFS for next Friday , lotta time to sort

06Z GFS has raised temps. during final week of Jan.  by about 8 degs. per day from its previous 06Z run.      Has been happening since mid-Dec to various GFS runs.   It does make it wetter as a consolation prize.

Someone posted the 850 temps for some places down in the south that were modeled at 240 or 300 hours and showed what they are now...this is always a fun thing to do with the GFS...a few winters ago it had -20C 850s at Jacksonville at Day 10, it ultimately verified at around 0C

I am surprised there's not more comments on the 0z ECM...that's an extremely impressive airmass Tuesday-Thursday next week with many suburbs probably falling below 0F if they have snow cover. The 0z ECM shows a reload at Day 10 with the PV diving into Southeast Canada and -16C 850s moving back into NYC. We haven't seen this type of sustained cold for a while. I think the snow threats will develop with that pattern, and we'll probably see squalls with an arctic FROPA.

The GGEM brought back the miller B yes that is currently progged to be OTS but it also has another big storm at hr 228

The Euro is just a day faster with this system , just not as deep at the 7 - 8 days timeframe .

The GFS has the ridge in the east followed by a frontal passage.

Totally different look .

Many days to work out details . but I am inclined to believe that the trough is still in the east next weekend .

well,

1. you need to fight off the dry air, which is shown in this sounding

NAM_218_2013011712_F12_40.5000N_74.5000W

2nd, your bl is pretty darn warm so you need heavier precip rates to wet bulb down, .1 over 6 hours won't do that.

STOP WITH YOUR SCIENCE.

I find that unusual too. Just baffling when you think about it.

You guys seem to forget that this is the norm. To get snow all the way to the coast on a consistent basis is rare. Even for mid-January.

Relax guys, we're still not even half way through the heart of the snow season. Still a solid 6-8 weeks to go.

This is our coldest part of the year on avg. Having bl issues in mid January, in which climo supports our coldest avg is unusual.

You live by the Ocean. In this part of the country it's a lot more about longitude than lattitude. Unless you live in Maine. That's why DC can get all snow and NY can get rain.

No Dc can get all snow with a hugging costal low, because our wide direction torches our bl. I can count on my one hand how many time I have seen dc all snow, and NYC rain. Your post is just a off the wall statement

ths is kind of silly...nyc averages a good amount more snow than dc it is the lack of a good cold air mass and precip  rates
