The 12z GFS is a repeat of Feb 8-11, 1994. We get 4" from a mod snow event on 2/5, then a MECS/HECS on 2/7. Certainly an interesting pattern coming up. What a winter we have had, even just in terms of storms to track.

 

For fun, the larger storm on the GFS was 12-18" for all with 18-21" in the Philly/SNJ area. 8-10" of snow in a 12 hour period. All per SV.

The first storm is probably some type of mix ..but looks like a very interesting week

If this GFS is right with its handling of the MJO heading into 7 then the EPO wins as the ridge will get beaten down

If the Euro is right ( I don't think it is ) the that SE is stronger and its wetter

Watch the MJO it will give u an indicator as how strong the S E ridge will be.

The Euro ensembles continue to block up tha PAC thru the poles and wants to block

Greenland too the GFS has neutral look to it in the LR.

So I will focus on the MJO if it comes around then its game on .

Feb 3-10 on the 18Z GFS looks like a total of 25" SNOW(2.5"equiv., almost all while under 32 2mT) for two events in NYC. On another note there still appears to be a sliver of heavy snow reserved for the extreme SE coastal areas next week, before our turn. Good Luck to all.

I also note that some members of the GEFS want to celebrate the coldest day in NYC history-Feb. 09, 1934[-15] by making a run for that target! Of course will not happen even with snow covered ground near and far of us, but graph looks wild!

I have created a February outlook blog at liveweatherblogs.com for the NYC Metro region.

 

Instead of spamming threads with posts like this, why don't you provide an actual link, as well as a paragraph or two of your forecast? It would be more effective for generating traffic to your site, and less obnoxious for people like me.

It's not my site, but I inserted a link.

Much better :)

 

Though the interface/design of that site is beyond terrible & freezes up my computer; you should probably start your own!

 I know. I talked to the developer of the site, and he is going to upgrade the software.

Not just software -- everything. Too many graphics, no real information, crazy faces staring at me from the sidebar... you should jump & start your own because whomever developed/owns that site has zero clue what they are doing.

First of all - that has to be the worst weather web site around - having to scroll through all the nonsense first - secondly you state in your link 

 

"So, with all the signals covered I think that the month of February will be average to slightly above average in terms of temperatures for the East Coast giving the current mjo state and the NAO/PNA configuration going right along with climatology, and average to slightly below in terms of precipitation just as climatology suggests, because of the unfavorable state of both the NAO/PNA which would increase the likelihood of a ridge along the east coast signaling drier conditions."

 

so how does  this prediction look for snow ?

How does a NEG PNA promote dry anything ? You injecting PAC moisture into the conus .

How does a SE ridge promote dry region ? Your aiming the moisture NE .

Nuet NAO is a non signal IMO

The MJO according to the GFS prob heads to 7. I'm not saying this is 94 or something epic

But I think it's anything but dry

Warm ? OK if you believe the SE ridge overcomes a NEG EPO driven pattern and the MJO out of 6 .

GRIM!!

IMO not good. The SE ridge will be poking it's ugly head, and will flood the area with warm air leading to rain chances when a storm does develop.

The SE ridge at 500 MB does not translate at 2meters with a NEG EPO

The entire height field is connected from the PAC thru Alaska over the pole. You're source region is arctic not polar. That low level cold air will push the baroclinic zone further than what the 500mb maps think it will be .

If there was a storm threat the SE ridge would promote a lake cutter. If there isn't a storm threat, that ridge would create warmer, and drier conditions for the region.

My issue with dry is the PAC is open for business. If we cut the cfsv2 in half its wet ( think this has done well )

No lake cutters with a neg EPO and the MJO heading thru 7. it may push the baroclinic zone north of 80. But

Pos tilted troughs tht come out of the panhandle don't like to cut.

They like to exit off the east coast close to where they entered on the west coast

Can't say zero cutters but I'm comfortable with tx to the nj

Yeah ,that's the power of the -EPO ridge and the strong Arctic high pressure pushing down form the north.
