September 2018 Weather in the Pacific Northwest

12Z ECMWF says we get into the action starting around 9 or 10 p.m. tonight.

 

I think that's a bit too late. Showers already into Port Townsend. Clouds are building here.

This front and the satellite look very much like Friday at the same time.

 

ECMWF shows some precip in the Cascades late this afternoon but the main frontal band waits until after dark to move into the Seattle area.

The ECMWF has a Wilmington, NC landfall for the third cycle in a row. Has been pretty consistent there.

 

Will it embarrass the GFS once again? Time will tell.

850s drop to 3 on the 12z GFS ensemble.  That's getting pretty nippy.

I told you a few weeks ago that you have had your straw man privileges revoked. You keep forgetting. ;)

 

Obviously people are upset with all the dying trees and these hellishly nice summers because they love this place.

Aren't you moving ASAP?

 

It's not love it AND leave it...

My preferences can beat up your preferences’ dad.

As I mentioned the other day I think this whacko ENSO regime we are in is probably responsible (at least in part) for these consistently hot summers lately.  We have been in a rut of summer El Nino head fakes or at least spikes to the warmest anomalies of the year during the summer for a while now.  It's fascinating how autumn, winter, and spring have shown no sign of the consistent warmth that summer has displayed.  At this point I think this month has a good chance of finishing on the cool side of normal.

You're right, Portland and other cherry picked locations were actually semi-arid until 1870 or so.

Definitely an exception to the rule, but there was an extremely hot, dry period from 1000AD-1250AD, which encompassed most of the western two thirds of North America below 50-55N, including the PNW.

 

There are indications that the Pacific Hadley Cell might have been even more expanded back then compared to now, given the rainfall gradient appeared to be displaced further north by ~ 500-1000 miles during the worst stages of the megadrought (depending on how one selects, interprets, and spatially interpolates the various available proxies for such phenomena).

 

Moral of the story: it could be worse.

Renton, WA was extremely lush the entire time, though.

We're out of range for the 12km NAM still, but you can see it is favoring the more southern route like the EURO.

I think the moral of the story is that it could never be worse than what it is doing at dca RIGHT NOW.

It takes the absolute worst possible track for Wilmington Metro. Looks like landfall is just to the west of Wilmington on Bald Head Island. It would bring tremendous storm surge up the Cape Fear River. us_model-en-087-0_modez_2018090912_99_480_149.pngus_model-en-087-0_modez_2018090912_102_480_149.png

Glass houses and stones.

 

Lots of stones.

Yeah it is a really bad track for them. Downtown Wilmington is kind of on a hill over 30' amsl, but most of the city is under that.

Gusty out. Rains are coming again.

 

Same here. Breeze feels good. 72 currently. Bit warmer than I expected today.
