Winter 2015-2016 speculation and discussion

Right.  There is no sign of overwhelming cold that suppresses the SJS.  If December ends up for arguments sake at +3, the CANSIPS suggests a D-F of around 0 to -1 total anomaly, which would put in in relative agreement with the JMA in our area.

 

Normal climate model caveats apply.

Add to that the Euro and Eurosips. CFS2 is the only torch, but it has been consistent with a very wet February, which would be very nice climo-wise.

The euro weeklies look really sad, week 4 the AO remains really positive.  The Euro monthly progs show a pretty good pattern for Feb and a slightly warm but not atrocious pattern for Jan.  If the euro weekly is correct for week 4 it's hard to see early January being very good though that far into the future,  the Euro weeklies could be way wrong.

Wes, from what I've seen the last few years, the weeklies are hit and miss. They did well last year with the AO though. Never really showed much promise there and it verified. Since they are just an extension of the 0z ensemble run they can be a little jumpy. Basically, the weeklies roll forward from d15 of the ensembles so if they are more wrong than right then the weeklies are usually even wronger. lol. 

 

With that being said, no blocking seems pretty obvious until something breaks there. And the low height anoms in the conus being focused out west seems like a fair forecast as well. Weather is never static like that though. I'm just hoping at the very least between now and the end of the month we get a modest pna + epo ridge even if transient. At least put us in the game for a long shot. Door to door futility of a winter month gets on my nerves. Last Dec sucked.

CANSIPS are showing a relatively dry February, which I thought was interesting.  It's showing cold and wet for January, which would be a pleasant shock, in my opinion!

God help us if this year is a fail. Looking down the line to the virtually certain NINA of next year, and probably the year after that, we run the risk of some pretty awful winters. And please, someone bump this if my suspicions turn out to be wrong.

 

What makes you say a Nina is virtually certain?

IDK Mitch.  I kinda liked the past three winters.  They were basically neutrals, but the two prior to last year were on the cold side of neutral.

every lr model I have seen (Euro, CFS2, JAMSTEC, POMA) have ENSO 3.4 below 0 come June/July of next year heading colder into the fall

 

Do any of those models even have any skill that far out? I have a hard time believing that's a lock.

 

If we get a weak La Nina the year after an El Nino the 95/96 comparisons will start coming in anyway. We'd also be due for our 7 year HECS, so I'd say I'm ok with a weak La Nina next year.  :D

Almost every big Nino has been followed by a Nina as well.

last year was as close as you can get to a weak NINO but not officially making it and the prior year was a La Nada, so those points I see

but next year, as it now looks, has ENSO temps dropping through the summer, which is a whole new look that I do not cherish from the last 2 winters

hey, hopefully I'm wrong on my statement that a NINA is virtually certain (didn't say absolutely certain) and temps flatten out, but the look of the climate models suggest ENSO keeps falling through the fall

That's a good point.  IIRC, in the spring of 2014, many of them were predicting a NINO for last winter..

Last winter was pretty close to a Nino. Of course the talk was super nino and the models were way overdone. But it's pretty clear still that you tend to see Nina after a big Nino. Not a given but worth considering.

We've had decent luck with a La Nada after a mod or strong NINO, but the NINA's (-.5C or less for 5 or more tri-monthly) have not been decent.

Winterwx, here's what I'm basing it off of in case you were wondering.

The hurricanes will be rockin' though.  Summer severe should take an uptick too.  You see, there are always pluses.

Not necessarily. If I recall, The winter of 2010-2011 was a La Nina winter, which followed the moderate El Nino of 2009-2010. The lag in the pattern caused the southern stream to still be fairly active in December of 2010, and that month rocked in the southern Mid-Atlantic. Granted, it's not a totally solid connection. There was also a lot of blocking. But still, the southern stream was still active and hadn't quite shifted out of the El Nino pattern.

2010-2011 should probably not be mentioned here. It featured below normal snowfall at BWI, IAD, DCA and RIC. Meanwhile, New England was clobbered.
