Front Ranger Posted August 29, 2017 Report Share Posted August 29, 2017 Judging by the models I'm guessing this happens in about five days? Yeah, I was curious too about how long the downstream feedbacks from the WPAC usually take to play out. Thought I've read 2-4 days, but can't remember for sure.

TT-SEA Posted August 29, 2017 Report Share Posted August 29, 2017 When I reviewed low solar years in the late 19th and early 20th century locally, I was impressed by the seasonal extremes on both sides. Lots of long, dry, warm summers and cold, snowy winters. I was thinking it would have a been a great time to live here... maybe its happening again.

TT-SEA Posted August 29, 2017 Report Share Posted August 29, 2017 Lol. Its true! 1906-07 for example. The summer of 1906 was awesome (by my standards which means the opposite of 1983 and 1993 type summers) and the winter of 1906-07 was also great. Lots of snow and cold here... bottomed out with high of 18 and a low of 4 on 1/14/1907 with 18 inches of snow on the ground. The summer of 1908 was spectacular... and the winter of 1908-09 was cold and snowy. The summer of 1909 was gorgeous... and 1909-10 was insanely cold and snowy here.

Kayla Posted August 29, 2017 Report Share Posted August 29, 2017 FWIW, playing around with autumn analogs, I keep getting a warm September, cold October, warm November type signal. Not exactly the most common progression, so I'm still tweaking things to see if it changes, but I find it interesting nonetheless. AKA last year?

The true trend over recent decades has been hotter summers and warmer, wetter winters. Consistent with a warming regional climate/ globe on the whole. There is plenty of evidence that lower solar activity is correlated with increased NH blocking, though. Most recently, 2008-11 was the lowest 4 year period of solar activity since the 1910s. It was also a very blocky period for the NH, and featured 4 major Arctic outbreaks in 3 winters for the PNW. Point being, I do think lower solar activity is your best bet for enjoyable winter weather at this point. Summer...harder to say. Quote A forum for the end of the world.

The true trend over recent decades has been hotter summers and warmer, wetter winters. Consistent with a warming regional climate/ globe on the whole.I'd argue it's a lot more complicated than simply warmer global temperatures. There are a number of factors that have pushed the system into a more +PNA/+NAM winter circulation in recent decades, and most of this would have occurred independent of any change(s) to the global temperature beforehand.

I am sure its just wishful thinking on my part... after the extended period of cold and snowy here last December and January with so many sunny days with snow on the ground... followed by an incredible long, dry, sunny summer. I am intentionally ignoring the mess that was spring in between.

Phil Posted August 29, 2017 Report Share Posted August 29, 2017 This isn't a result of warmer temperatures. It's a result of changes to zonal/meridional tropical Pacific SST gradients.

From what I understand, the largest watersheds into the metro area are to the W/NW. Couple of large dams there that were close to having spillage. Rain to the NE is not good, but as long as it doesn't fall too fast, the drainage system they have in place will function at roughly the same level it's functioning now - at least that's what I've heard from those living in the area.

There are also at least two watershed tributaries to the S/SW of the city, draining N/NE-ward. So I'm not optimistic, but I would love to be proven wrong here. Especially with the center of convergence poised to move north again later tonight or tomorrow, I don't like the look of this situation over the next 24hrs.
