Front Ranger Posted February 15, 2018 Report Share Posted February 15, 2018 The CMC ensemble mean is usually warm/high biased with heights, and even it sees the massive -NAM/-PNA phase locking to open March. That's skipping ahead quite a bit. The EPS is showing a deep -PNA at day 10...not so much with the -NAO. Quote A forum for the end of the world.

Farmboy Posted February 15, 2018 Report Share Posted February 15, 2018 FWIW, looking at models today, there’s some obvious disagreement regarding which wave to break into the Eurasian/NAO domain (which is probably necessary to sustain the -PNA through next month). The GFS was keying in on the first wave yesterday, but now it’s moving towards the ECMWF idea of having the second wave do the trick, which makes more sense mechanically, but will require an extra 5 days. Not a huge difference maker in the long run, but couid have short term implications for late February.Sounds like what Phil is trying to say is "winter cancel" for the sunday-tuesday event boys....

Front Ranger Posted February 15, 2018 Report Share Posted February 15, 2018 Phil went from being some kind of a savant to some kind of an amateur in about a ten day span there. Perception is a funny thing. People tend to get carried away one way or the other. Phil is a good LR forecaster. But LR forecasting is hard. If you get more hits than misses, you're winning. He says a lot of different things that relate to LR forecasting, and sometimes he'll look really good, other times really bad. And sometimes it has more to do with perception than accuracy. 1 Quote A forum for the end of the world. Link to comment Share on other sites More sharing options...

Yep, I agree. This is true for everyone who tries to forecast on longer timescales. We all have our unique stumbling blocks, strengths, and areas of general intrigue. I’ve been burned by strong western Pacific convection several times over the last year. Not something I’m happy about, but you’re always gonna screw up here and there, so all you can do is learn from it and move on. My area of academic research is actually intradecadal climate variability and paleoclimate, not seasonal forecasting. So I’m more “comfortable” forecasting ENSO/ocean oscillations and long term changes to circulation than I am forecasting seasonally. 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...

There’s already a -NAO/-NAM aloft, in the context of the resonant wave-2 pathway for WAFz communication. So your point is pointless, both in the physical sense, and in the context of my post. These 500mb/middle tropospheric circulations don’t occur in a vacuum. The entire system is in communication..it was the SSW/PV breakdown that was the trigger that opened the climatological communication pathway between the PNA/NAO, regardless of which one manifests first in the lower troposphere.

Phil Posted February 15, 2018 Report Share Posted February 15, 2018 That aforementioned pathway of communication between the PNA and NAO has always existed. It can be opened/closed/mediated on short timescales depending on the state of the NAM and degree of vertical coupling present (for example, coupled/baratropic, coupled/baroclinic, noncoupled/baratropic, noncoupled/baroclinic), which can hinge on QBO/tropical forcing conduits, etc. But again, it’s always been there. It’s why most of 2017/18 has been +PNA/+NAO in the face of an overwhelming -EPO. It’s why the SSW reflects a pathway to reverse said system state.

Front Ranger Posted February 15, 2018 Report Share Posted February 15, 2018 18z GFS also shows less snow than 12z, especially for the south sound. Models continuing their wiffle-waffling on snow totals, as expected. The only model which has been fairly steady is the Euro... fairly steady in not showing much, that is. Remains to be seen if that's a good thing or a bad thing. Yeah, and even the Euro has waffled between favoring the north sound or areas further south. Quote A forum for the end of the world.
