Tundra Posted October 13, 2016 Report Share Posted October 13, 2016 Still lots of uncertainty on how this Sou'wester will form and track up the coastline. Expect more model flip flopping as we get inside a day out and even then we will need to rely on the GOLU model because these Sou'Wester's sometimes veer off course. A slight shift here and there will make all the difference in the World. Quote Link to comment Share on other sites More sharing options...

Tundra Posted October 13, 2016 Report Share Posted October 13, 2016 I don't know if anybody has heard of this model but it's the MF-ARPEGE. It was on the meteocentre.com website. Basically it's the France Model. Here is it's newest 12z run. The wind gusts are insane. http://img.meteocentre.com/models/arpege_amer_12/WGE_PN_054_0000.gifhttp://img.meteocentre.com/models/arpege_amer_12/WGE_PN_060_0000.gifhttp://img.meteocentre.com/models/arpege_amer_12/WGE_PN_066_0000.gif Quote Link to comment Share on other sites More sharing options...

In KOMO planning meeting now. Will tweet more soon. Sounds like NWS/media outlets starting to lean towards Puget Sound-focused scenario. It's a fair guess at this point. I'd say Puget sound is likely to see some of the strongest wind gusts in a few years for sure. I think Vancouver, BC and Portland are more likely to have a dud storm given they're on the periphery of the current trend. Quote Link to comment Share on other sites More sharing options...

Guest Winterdog Posted October 13, 2016 Report Share Posted October 13, 2016 I am selfish but BRING IT!! Even though I do share a fascination with all of you about the coming storm I have to admit I am not looking forward to the hardship and discomfort it may bring. Days without power, cooking on the barbecue, no internet, heating with the wood stove, stumbling around in darkness etc. are not enjoyable. Instead, give me an arctic front with plummeting temperatures and blowing snow. There is a beauty with the snow that makes the hardships blend with the aesthetics of a smoothed and freshened landscape as opposed to the damp, dark, and broken sweep after a major wind storm. I pray there is no loss of life resulting from this reckless visitor. 2 Quote Link to comment Share on other sites More sharing options...

I pray there is no loss of life resulting from this reckless visitor. That is totally understandable. I'm pretty fortunate because I live in an area that is usually very quick at restoring power. I can't think of a time in my life where the power was out for more than 18 hours or so (that includes when I lived in more rural areas than I do now). But I could definitely see it becoming a drag after a day or so. Quote Link to comment Share on other sites More sharing options...

westcoastexpat Posted October 13, 2016 Report Share Posted October 13, 2016 You're probably right and this is a nonevent for everyone. No need to panic or prepare, just a normal breezy wet day. I definitely don't agree that it will be a nonevent for everyone. 55-65 mph gusts are nothing to sneeze at in my opinion. I don't think it's fair to say that it will be a "normal", "breezy" day. We haven't had a storm like this in a few years. Especially with the trees having their canopy, power outages will be likely for a lot of areas. I'd also say that having water jugs would be prudent, especially given the high rainfall... reservoir water could become contaminated.

Seems common up here, for something that looks like a direct hit, ends up turning towards northern Vancouver island in the last 24hrs. I think what makes forecasting so difficult for the PNW, aside from the topographical elements, is the lack of sampling before a system comes onshore. For example, forecasting for a winter storm out east becomes a lot easier once the system makes landfall in the west, because the system has so many stations monitoring its behaviour -- as a result, models tend to converge on a solution. But for the PNW, you've got a system out in the ocean with very sparse buoy data. It's very difficult to model a system with such limited data. It's mainly why I tend to be more conservative when forecasting for events in the PNW in the medium range. We are entering the short range forecast now, with 48 hours until Songda strikes... this is when the modelling gets really interesting.

Prairiedog Posted October 13, 2016 Report Share Posted October 13, 2016 Climatology takes over most of the time with these storms. It's truly the exception that we get smacked. Not unlike snow storms and arctic outbreaks. Climo. Time and time again these storms spin up, bomb and make a beeline north. It's just what they do. It looked like it had a chance to nail the Portland area but I never felt it would just because of climo as much as the models (some of the models) said it would hit near here somewhere. If it were within maybe 12-18 hrs and it looked like a lock then I'd jump on the band wagon. It will still and can possibly get pretty windy here in the N. Willamette Valley but it probably (at least at this point in time) won't be one to write home about. Now watch it make an idiot out of me. I won't be upset if I'm wrong and I loose power for a few days. I like windstorms! I don't like seeing people having to deal with the stress of property damage or worse either. 1 Quote Link to comment Share on other sites More sharing options...

We are entering the short range forecast now, with 48 hours until Songda strikes... this is when the modelling gets really interesting.The vast majority of data assimilated into the modeling is satellite derived. There are dozens of radiosonde launch sites upstream/over the Pacific, and when you get down to it, the real error differential between the NPAC/west coast and NATL/east coast is statistically insignificant. An error in one domain will correspond to an error in another domain, which will correspond to an error in another domain, so on. So in the end, you're dealing with the inescapable void of chaos (blah blah, can't measure the speed and location of a particle simultaneously, blah blah).

westcoastexpat Posted October 13, 2016 Report Share Posted October 13, 2016 18z GFS looks to be about the same strength/track as 12z. 973mb off coast of Olympic Peninsula, 980mb up near Vancouver. 18Z GFS tightens the gradient on the south end, shifting the impacts a tad north but increasing the strength on the southern side of the low. Astoria to Olympia really gets hit incredibly hard on this run... We're talking 70+ mph gusts GFS does continue to ease off on Portland... still a good wind storm there but nothing devastating.

TT-SEA Posted October 13, 2016 Author Report Share Posted October 13, 2016 I'm thinking Hannukah Eve storm in '06 is another good analog to look at, in conjunction with Inauguration Day storm. Although, the Hannukah Eve storm came in more due-west and was a tad stronger (957mb) but still relatively similar to this one. Trajectory on the 2006 storm made a big difference for my area. That was a perfect track and strength to hit this area. A storm moving northward along the coast is going to hit areas near the Sound much harder than out here.
