I'll take it and am also drooling over the map @40/70 Benchmark published a few days ago. Both of my guest rooms are put together so plan on coming out for the paste bomb 

I may have to put in my reservations ahead of schedule

This better be a good winter out at DCL.  I'm gonna be chasing out there for every event.  I'm not even gonna pay to get the drive up the mountain plowed so I can use snow chains instead.

@BlizzardWxWhen are you going to have the new EURO seasonal uploaded onto your site?

The other site shows -.41 as of 9/10. Still a rise, but not as dramatic.

Sorry on the slow reply, we have a new baby in the house so I've been pretty checked out. I am now doing some backend overhaul to clean up some bad coding from one of my AI agents but I will get the seasonal forecast on there soon if it didn't fix itself already. Anybody who has worked with AI knows what I am talking about when I say extreme tunnel vision in AI agents makes coding "islands" and if you don't manage it carefully it can get pretty out of hand. 

The PDO calculation is a little higher on mine, probably because I went to some effort to try to normalize out the global warming signal. It should at least trend up and down at the same rate as NOAA but have less of a negative bias.

At least the IOD has finally popped positive as long expected. This along with the rising PDO and resumption of the strengthening El Nino all points towards a different winter ahead than what we have seen for much of the last decade. I suspect warm and wet down here for most of it, with a window for some cold or snow sometime Jan or Feb.

Congratulations on the new baby and love the site.

Please let me know about anything else you want added. I am going to attempt a shorter time scale MEI at some point as well, like perhaps a rolling 1 month average that updates daily or something like that.
