GobBluth Posted November 21, 2016 Report Share Posted November 21, 2016 Positive signs with the 12z in that the pacific gets shut down. Until then, it's going to be a very stormy and incredible snowpack building pattern over the next 7 days.good phrasing. it's seemed the pacific has been raging far too strong to allow for blockage.

Phil Posted November 21, 2016 Report Share Posted November 21, 2016 Not sure why Phil is being criticized honestly. While it's true that the -NAO may help us out, I doubt we see any substantial cold until the Pacific shuts down. We're all hungry for some cold, but lets not lower our standardsThanks man. I agree with your take. 1 Quote Live Weather Cam: https://www.youtube.com/live/KxlIo8-KVpc?si=xKLCFYWbZieAfyh6 PWS Wunderground https://www.wunderground.com/dashboard/pws/KMDBETHE62 PWS CWOP/NOAA: https://www.weather.gov/wrh/timeseries?site=F3819&hours=72 Link to comment Share on other sites More sharing options...

Yeah people getting excited over the coming week or so for any kind of appreciable cold air are going to be sorely disappointed.

I've been watching this time frame for quite a while as tropical forcing enters the EHEM, promoting height rises over the pacific. Curious as to what signs you see? Thanks A combination of things, but I would say the biggest thing is a bit more of a signal in the longer-range noise...and several runs of decent agreement in NE Pacific teleconnections (EPO, PNA) suggestive of some sort of digging trough along the west coast or across the interior west (depending on placement of offshore ridge). Looking at a cluster analysis of the Euro weeklies over the past week there's been a clear shift in member camps toward a pattern conducive to a cold west, however it still remains a minority solution set (~30%). Seeing a similar pattern now translating into the 11-15 day period in terms of both 500 mb height anomalies and teleconnections on the ensembles has bolstered confidence in the overall pattern change. Details are still to be determined. Of course the biggest risk is that the cold tends to slide down into the Plains with minimal/just leakage into the interior west (which would mean little effect for western OR/WA). 2 Quote The Pacific Northwest: Where storms go to die.

Hopefully we continune to see improved model runs and maybe a bit of consistency to go with them Keep us updated! I don't tend to forecast out 30 days or seasonally, or put a lot of stock in the CFS/Weeklies beyond about 15 days...but I am encouraged when I see some semblance of agreement and what appears to be a solution that models are coalescing around. I don't mind the monthly and seasonal predictions, it's all interesting, but I don't generally put stock in them beyond just a broad-brush tendency in a year with a pronounced ENSO signal for example. 1 Quote The Pacific Northwest: Where storms go to die.
