HM I also like the 2/25-3/7 period. You looked into that at all? I did well with my 1/25-1/30 prediction back on the 12th.

 

Well there seems to be an issue in the Tropical Forcing department with 2 areas creating a signal. Therefore the signal has become muddied; but, I suspect general Indonesian forcing to take hold in late Feb for a time, bringing warmth. I would say just after that period might get interesting again but I'll get back to you on that once I let the Tropics settle into the old brain later today.

 

Good job with the 1/25-30 call. What are some of the things you are basing your calls on so I can understand why you are going cooler to end the month?

there are different schools of thought in this forum.....there are definitely those that punt events that are a nuisance.....but many of us would welcome a mixy hybrid that thumps 2-4".....I never punt those events in any winter...

 

Yes, I think it is very understood that this Feb pattern isn't the best. But, you have to respect a looping PV in Canada and an active southern stream. Yes, this doesn't force a storm but it certainly increases the chances for one (plowable snow, 2"+).

 

I think 1975 and 1993 show some similarities to this year's global parameters with 75' being too niña for this year and 93' being too niño/volcanic for this year (+AO tendency from Pinatubo).

If a sloppy wet snowstorm was being modeled ~ 2/10 after a couple of crappy clippers and inland runners, there would still be complaints about the lack of NAO and how this winter has gone. I told the MA to punt when we should earlier in the winter but I can't say to punt yet with this period coming up. If I'm wrong, I'm wrong but I really do think there is something to this period coming up.

Glad that you are dropping some good info in here for us. I hope it does pan out the way you think it could and will be interesting to watch.

Hey it's nothing; I enjoy talking about this stuff. I hope it pans out too because this winter has been dreadful.

yeah...plus I also enjoy the discussion and learning process too.....January 30th is a little early to say we can't get a 3"+ event...

Same here, I enjoy the discussions and learning. Given the issues with the MJO right now, I wouldn't totally buy into "no more winter" after mid-Feb. However, I would keep expectations way low for a few reasons:

1. Stratosphere is beginning to recover in the upper levels. It is possible this could downwell to bring +AO conditions for March. However, my own feelings on it are that it won't be that easy this year since bottom-up disturbances may still be possible. Everyone fears this because it is what happened last year after the SSW mid-winter.

2. The default pattern this winter and default tropical forcing would favor warmth.

3. Lack of snow cover is a big problem going into late winter and mustering up sufficient cold air for snow. We'll see if we can get this repaired to our north over the next couple of weeks.

looks good at 384

 

lol...or looks good at "next year".

 

all kidding aside...the reality is that we're in a rut and it's hard to break out of ruts.  it takes work.  we're gonna need a bigtime pattern changer, and i'm not experienced enough to know when that will be.  i do appreciate weather like this, though...if it's not gonna snow at least i don't have to be outside freezing my ass off.

The euro run is a lot more promising than the GFS run...Lots of model mayhem...I wouldnt write off the 8-10th

I did a CWg article that got waylaid by comcast e-mail server problems and then the incoming line of convection.  I don't like the 8th- 10th at all unless the mean 7 day pattern is really way off.   The mean by the 9th is a warmer than normal pattern so you'd have to be extremely lucky to get anything.   The southern stream getting going is nice if we can get a storm to go to our south.  Initially, I don't think they will.

DT said something about next weekend, I believe the 10th, possibly a coastal. Showed above precip on graph up the coast  Dont know exactly what graphs he was using but it showed precip to just inland including the main I-95 cities.Also , I think he said snow too.

Now that is what I call a definitive forecast lol.

Did you read what you wrote?

that is what I wrote, I,m simply telling you what he said. and you replied

If you dont call that a definitive forecast with day, date precip type and type of storm , then I dont know what to tell you!! I,m a newbie but read and listen to all points of views To me that is definitive. If not you so be it!!I,m done posting. .

I've seen a lot worse patterns than the 18z GFS at day 10...rex block/split flow so we get a southern stream and systems move across the south.....it is not an otherwise great pattern but it could deliver something small-medium

 

I've never though the last couple lr runs were "terrible". Not showing snow is one thing but it's not like there isn't cold air available and the ridge west keeps re-establishing itself over and over. The pv isn't static so it flexes and wanes its influence in the ml's over and over. I've conceded that a nice -nao prob wasn't happening. All things considered we're looking pretty good. At least imo anyways.

All I've watched for all winter is getting enough of a W coast ridge to usher the clippers down our way.  We have seen that happen some and I would like to think we will cash in on one with some STJ assistance.
