Winter 2012-2013

If busted forecasts were so valuable people would have accurate winter forecasts by now. That isn't the case, and anyone who does better than 55/45 is a genius (and not real). The 'accurate' forecasts people tout are based on a small sample of years, and as long range forecasts accumulate the winning & always goes down (besides the fact that 'verification' is subjective).

Re: analog96--

usedtobe may have never called for a big winter but at the same time analog has never called a correct forecast, so which is worse? usedtobe is fantastic & one of the MA subforum's most valuable assets, especially during the winter.

Did they change the calendar so that July is now part of winter? :whistle:

No, but they have taken March away. We are down to Dec/Jan/and first two weeks of Feb.

Sure, we may get a freak storm here and there like last October, but the winter season has def. shortened.

CFS

Ant,

This is the old version of the CFS, there is a newer version, CFS V2 that is out on the CPC website.

Here is what it has to say for December into January

usT2mMonInd5.gif

December looks solid, negative temp anomalies in the east and positive temp anomalies in the west, suggesting a +PNA and an east coast trough. Also note that it has positive anomalies by Greenland and the Davis Straight, which may indicate a -NAO.

January looks okay for our area, not as much blocking as December FWIW, but there is still ridging going on in the west.

Take this all For What It's Worth, since this is a not so reliable climate model, and it is still several months away.

Latest JAMSTEC for DJF has quite the weak Nino signature with a sexy look across the mid latitudes. Warmth in the nern Plains/sern Canada and chill across the South/East.

Classic west based weak Nino w/ warmest SST's in the regions 3.4/4

Take it FWIW. For me, I won't be thinking about my winter outlook until late November, after last year's debacle.

2002-03 repeat? Pay attention to the 2nd week in October. In 2002 we dipped to below normal and really never recovered (save the one day spike here or there) until mid-late April. It is the 10 year anniversary of that winter just like last year was the 10 year anniversary of the awful 01-02 winter and look what happened in 11-12.

Interesting coincidence.

I dont like how Alaska is cold on those maps. That usually means that there could be a Alaska death vortex over there.

Lots of acorns on my oak tree. Doesn't that mean a snowy winter is incoming? (or is it the other way around?)

-.1 to 0 is 95% of the cold readings showing up on that map. The rest is actually above normal except extreme western areas but still that is only -.1 to -.3

That's harmless. I'd do cartwheels if that map comes to fruition.

Kind of weird since weak Ninos do not support a Miller A track at all. Then again, its the JAMSTEC.
