BLI snowman Posted December 17, 2015 Report Share Posted December 17, 2015 Coming through, loud and clear! Note the word "at" followed by "best". Also note that I'm prognosticating for the mere earth-bound locations around our region. The divine holy zen spots such as OLM are likely to get absolutely plastered with wet cement.

Deweydog Posted December 17, 2015 Report Share Posted December 17, 2015 2009 was kind of a freak thing and isolated strictly to the Portland area. But it goes to show...the highly unlikely can and does happen.Yeah, those well-mixed, progressive WNW flow snowstorms can be a real ***** to forecast...

BLI snowman Posted December 17, 2015 Report Share Posted December 17, 2015 I just dislike propaganda put out by certain people and then the expectation that everyone buy into the propaganda. I don't dislike the love of cold and snow. I love cold and snow. But a real discussion is often derailed by delusion. You see the situation clearly. Matt does as well. So does Jared. And, as I mentioned, I really like Rob's detailed analysis. The bottom line is that things haven't really trended towards a meaningful pattern change at this point. We're a ways off still. The real story has been and will continue to be the filthy amounts of rain, either though it's understandably far less enticing a discussion to have. Also, in looking at our wettest Decembers on record, there's really no clear signal. Big mixed bag of patterns the rest of the winter. Decembers like 1996, 1955, 1933, 1917, 1882, and 1867 really stand out for their rain and there's some huge contrasts there in JFM. 1 Quote Link to comment Share on other sites More sharing options...

BLI snowman Posted December 17, 2015 Report Share Posted December 17, 2015 This thing is pretty hit/miss GFS-lite model output most of the time, but it shows about 3.7" of rain at PDX on Thursday and it usually doesn't error too far on the wet side. Gonna be some problems if that happens. Quote Link to comment Share on other sites More sharing options...

Phil Posted December 17, 2015 Report Share Posted December 17, 2015 PV breaks up. A least it will shake things up. We might score at the onset of that change.Question is, will the tropical forcings still favor NPAC height rises by the time it breaks up (mid/late January)? 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...
Phil Posted December 17, 2015 Report Share Posted December 17, 2015 Never said that. Usually quotation marks are for quoting people.You kind of implied it. There is plenty of cold air sitting just to your north on these runs. The PV is not what's holding that from sliding a little further south.

ShawniganLake Posted December 17, 2015 Report Share Posted December 17, 2015 Very cool... do you think it will stay snow as the precip gets heavier? I am not sure how it works up there in this situation.Usually the heavier precip helps, at least until the upper levels warm or until a south wind scours out what cold air there is. Typically these are a rain to snow to rain situation. I was surprised it started as snow actually. Precipitation is modelled as being pretty light up here, looked like the 7-10am period might produce an inch or so. It's borderline, it's 40 degrees and raining only 5 miles from here and 500ft lower. Quote Link to comment Share on other sites More sharing options...
