I have already started a thread on the potential for a winter storm around 12/11, and I think the pattern that we had in the last couple of months would EVOLVE to something we had late January '06 into early February '06.
http://www.nycmetroweather.com/forums/inde...?showtopic=8259
But it is very interesting that the GFS follows my logic...
I think the GFS has a cold bias between Nov 27th up until the 4th of Dec
I 100 percent agree with the GFS about a strong cold front around the 4th...and the potential to see daytime highs in the 30s.

12z GFS:

Now what happens on the Dec 9th-384 GFS is not all fantasy at this point...
Energy in the SE Pacific eventually gets picked up by a trough/short-wave energy building down, and moves-in and around the coast because of a ridge in the Atlantic.
Main players:
-Ridge in the west
-coupled with a Ridge around MX and the Gulf
-Ridge in the Atlantic (favorable)
-Upper level Low covering the Northeast with its cold
-Another upper level Low in Canada... coming on the backside...the picker-upper for the energy down south
-Upper level High in Canada (somewhere west and close by) ...the mechanism that will drop the trough.


Check this out...(looks like the cold upper level High is way up there on the left...and the trough is in Canada on the right):
btw, this is still a bit too unclear and convoluted...but I really like that strong ridge building into the west along with that ridge around MX...a good step forward.

MY THEORY-PATTERN CLAIM:
STRONG TROUGH--COASTAL STORM--WINTER STORM POTENTIAL FOR THE MID-ATLANTIC/NORTHEAST FROM 12/9-12/13 (avg 12/11)

A PATTERN IS A PATTERN...IT REPEATS ITSELF!!!!!
Generally speaking,
A tropical entity marks a new cycle of the same pattern. (Kyle, Omar, Paloma, Invest 96L)
Just take the day a pronounced-remote tropical entity formed, find the difference between that tropical entity and the entity that formed in the last cycle.
So you have...
1)
START DATE:
Weak-Invest 96L (11/24 to 11/28, to be safe...because usually each tropical entity marks a warming trend in the EAST) and then Paloma (11/5)
28-5= + 23
24-5= + 19

2)
THE EVENT DATE (END OF CYCLE):
The benchmark/date for the event that you are trying to find...which is 10/28/08- This is when we had that strong coastal/ some snow and that strong trough...I am assuming that this is just a cycle in a pattern so something like this should happen again? Right? (started with 9/28/08..then 10/28....but I elaborated the pattern to 11/20/08) It did happen again.

I take 11/20/08- the date I came up with on November 3rd using my pattern...remember that I was generally right...we had very cold conditions...and we had a couple of coastal chances that resulted in a few snow showers...I will also assume that this event marks the end of a pattern.

-Now you just add the (positive) difference you found in step 1 to step 2 in order to find the next date of a similar storm:
(Start difference subtracted or added (in this case) to the event date)

20+23=13 of the next month or 12/13/08 TO
20+19=9th of the next month or 12/9/08
AVG DATE: 13+9/2= 22/2=11- December 11th, 2008 for the next coastal with cold air advection in the area.


Now what I am assuming here is that this pattern is progressive and moves at a constant rate from one month to the next; however, that is not always the case. The High/Ridge out west failed to move east, causing our 11/20 system to drift out to the east. This is considering that we had the cold air advection but we did not have enough warm air advection.

Also, one must note that the major changes is where everything forms because of the amount of cold air allotted. The monthly variations should tell that story. I also note that storms usually formed farther west and south with each passing month. Should that ring a bell? I mean think about it. Hurricanes form the same way...first they can form in the Atlantic, then the threat drifts to the east Caribbean by October, then to the deep-west Caribbean by November/December.

Anyways, in order to know if your cycle will move at the same pace as the one before...you must have an analog. I found similar features and pressure/temperature variations in late January 06 to February 11-12th as i did in Nov 5th to Nov 23...which brought me to the same general date-12/11 (using the 2/11 snowstorm as a benchmark)...It is the same date for a THREAT of a major storm/coastal with a strong trough present.

This is assuming that January 24 06 to February 11-12 is as cold as the November 24th- Dec 11-13th period ...and it is assuming that even though the
1/24/06-2/12/06 has differences with 11/5-11/23, it still managed to come to a similar result...Result for both analog period and November period: a strong trough and a coastal threat. Giving me some belief that there is a natural pattern present.

Now I am just using the long-range models (GFS) as guidance.

You have to love how he points out potential cold air when those temps are being observed currently yet he'll do a whole topic/post on a storm literally weeks from now.

It's worth it because most folks around here are realistic about weather and weather potential. So just separate out the juvenile wish-casting posts from realistic ones. The pattern we will be in does allow for the potential of a coastal storm and once you cross the first day or two of December you take that potential a lot more seriously. But you only use 4-6 day out models for reference and then you see if they can consistently hold the storm, and hold it in a near stationary track and position, for a day or so of runs before making a realistic assessment. To use a 10-15 day out GFS - well that's pure fantasy and wishing along with the need to make a thread based on wishing and hoping rather than science. Just look at how his thundersnow thread is about to crash and burn.

If you give these people a hard enough time they wont want to post. Sometimes it is better not to ignore but rather give them a hard time. Whatever happened to the guy from Buffalo or someplace out that way. Forget his name. I dont hear from him anymore as well as others we gave hard time to.

Brett,
Nothing in meteorology is sound, at this point I think there is the potential for such a winter event to occur around the given time. I started a thread on the pattern that I think we are in , and I believe a new cycle in this pattern will start today and last until December 12.
Basically, the pattern starts on the cool side depending on the month, then warms up and fluctuates, then cools back and below the starting avg due to a strong upper level trough, which eventually results in a coastal. This pattern is seen in November, October, September.
There are all also sub-patterns in every one pattern, governing how entities form, and progress. I picked January 24th to Feb 12 06 because of a similar pattern in temperature and pressure that we have seen from November 5th to November 23rd. I used the GFS and the EURO as guidance in order to see if similar entities are seen on November 24th that have been present on January 24th 06, and my comparison has been fairly positive.
Also, I think my comparison should be fairly positive because of the 'amount' of cold air that is already in place and the potential amount of cold air that can be in place in December (given the records). I think late January 06 to early Feb should work out well for the next couple of weeks.
I started this thread because the GFS at this point resembles the late January '06 to early February pattern, which eventually leads to a strong storm roughly 5-6 days after the strong cold front. Does that sound familiar? It should... Overall, the two major differences in the monthly patterns is the duration of a specific event ,and the amount of cold air that is in place.


I continue to like the 384hr GFS. This pattern fits the Feb 10 06 like pattern...
I mentioned the main players in the first post

We are getting hotter...the 384 hr looks more plausible in terms of the players involved...I especially like the complex forming in south TX.

Oh new era grow up and stop throwing your toys out of your pram!
All people are trying to say to you is the storm is too far out in time to have any clue what will happen
Hell you can't even know if it'll still be there 10 hours from now.
Too much can happen between now and then to talk about this potential storm with any seriousness.
Just note that it's there and wait to see what happens.

Hope is what keeps us moving. A wise person should never think that his forecast is right; however, a wise person should always hope that his forecast will turn out to be right. Hope marks positive change, without hope a person cannot change his views for the better. I hope to be right so I can correct my mistakes before I am undoubtedly wrong. As an example, I hope to be right as in I hope to win. There is always that chance you will win, but having hope gives you the extra edge to push yourself and come closer to being the actual winner, or in this case coming closer to making the actual right call.
