TT-SEA Posted September 28, 2015 Report Share Posted September 28, 2015 12z euro still going with it.image.gifYep... it's going to happen. ECMWF is too adamant. Just checked the detailed map from the 12Z ECMWF and it's sunny for most of the region by Saturday afternoon and in the upper 60s. So it still could be a very nice weekend. The rain comes through quickly on Friday night.

TT-SEA Posted September 28, 2015 Report Share Posted September 28, 2015 Full 12Z ECMWF run is great. Sunday has the potential to be really nice... sunny and well into the 70s (near 80 around PDX). And then just a continuation of ridging all of next week.

The operational 18z GFS doesn't even break the wave into Alaska/depicts a destructive interference pattern. You can already see that it's heading in an ugly direction..one that will probably lead to a large GOA vortex and warm rain on W/SW flow.

Phil Posted September 28, 2015 Report Share Posted September 28, 2015 ECMWF ensemble mean looks fairly benign with some ridging in the long range The EPS has offshore vorticity much farther west in the 11-15 day range, allowing for a sharper ridge into Alaska/retrogression potential w/ northerly flow aloft. The GEFS puts a giant vortex in the GOA, flooding the region w/ SW flow.

Black Hole Posted September 29, 2015 Report Share Posted September 29, 2015 ECMWF weeklies that came out today look warm and dry for the core of October. Hints of a pattern shift towards the end of the month but that's a long way out. CFS has been showing this for a while though so I guess the slow start to real fall weather we have seen in recent years will continue.

TT-SEA Posted September 29, 2015 Report Share Posted September 29, 2015 00Z Canadian sticks to the ULL scenario for Friday night/Saturday morning. Most of the weekend ends up nice. That seems to be a good thing overall... it blocks up the pattern more next week and results in a longer period of nice weather.

I guess 1997 was pretty wet in October.I think 1986 was technically moderate. As far as warmth goes in strong ninos it's limited, at shawnigan lake at least. 65 had a warm October but 57, 72, 82, 97 were average to below. For moderate ninos, it's a 50/50 split for October temps. 63, 86, 87 mild. 91, 02, 09 cool. Quote Link to comment Share on other sites More sharing options...

I guess 1997 was pretty wet in October. All over the month. 2009, 1997, 1982, 1972, and 1957 all had significant cool and/or troughy periods for much of the West in the first half of the month. The good news for you is that several of them were relatively dry for the PNW. How wet it was at your particular location in the West is another matter, but I don't think that's what Black Hole was talking about with the Euro weeklies in mind.

TT-SEA Posted September 29, 2015 Report Share Posted September 29, 2015 ECMWF has not wavered at all with the ULL solution... GFS still has not caught on.

TT-SEA Posted September 29, 2015 Report Share Posted September 29, 2015 And the GFS just came around on the 12Z run. The ULL scenario is better for nicer weather afterwards.

Jesse Posted September 29, 2015 Report Share Posted September 29, 2015 The GFS finally caved. What I like about the solutions that show the ULL is that its passage seems to keep the really warm weather at bay for the first week of October. Runs without the ULL had the offshore ridge build directly over us next week, while runs with the ULL keep it mostly offshore. Quote Link to comment Share on other sites More sharing options...
TT-SEA Posted September 29, 2015 Report Share Posted September 29, 2015 Probably 80 at PDX on Sunday with the ULL scenario. Warmer than earlier GFS solutions.

TT-SEA Posted September 29, 2015 Report Share Posted September 29, 2015 And now the 12Z Canadian has abandoned the ULL solution.
