Phil Posted December 31, 2015 Report Share Posted December 31, 2015 Jimbo may seriously regret that east coast weenie hate speech. Karma is one hell of an atmospheric driver.Lol, at least you know who/what to blame if everything goes to s**t. In the midst of a super-niño, it's probably not the smartest thing for a PacNW wx-weenie to do. That's analogous to an Atlanta weenie trash talking Juneau in 1949-50.

TT-SEA Posted December 31, 2015 Report Share Posted December 31, 2015 Up to 39 at SEA... but with a dewpoint of only 17. Don't think fog will be a problem for the fireworks tonight as was mentioned in the news yesterday. We have the benefit of getting into a very dry air mass before the inversion really gets going. That is very nice given its been such a wet month and you would think an inversion would have the added help of lots of residual moisture. But now the ground is hard and frozen. And with some cooling at the upper levels on Sunday and Monday... the inversion might never become really established. http://s30.postimg.org/bgkqm0q5t/seattle3.jpg Quote **REPORTED CONDITIONS AND ANOMALIES ARE NOT MEANT TO IMPLY ANYTHING ON A REGIONAL LEVEL UNLESS SPECIFICALLY STATED** Link to comment Share on other sites More sharing options...

BLI snowman Posted December 31, 2015 Report Share Posted December 31, 2015 face value, what precip type? Unfortunately the precip is associated with a warm tongue of air aloft. If we get the precip to rotate this far north, 800/850mb temps are almost certainly going up above freezing. Which would mean freezing rain at best (worst).

Phil Posted December 31, 2015 Report Share Posted December 31, 2015 True, but this isn't your everyday meridional flow. The AO is progged to absolutely tank. That's some major Arctic blocking being shown.I think the rapidity of the transition to the -NAM is more notable than the strength of the blocking itself. I think we all foresaw the midwinter NAM flip based on the forcing parameters in play, as we were discussing it back in October/November. Looks like the GEFS consensus is for a drop to around -3 or -4 standard deviations. So while significant, not very unusual. Of course, this doesn't preclude the -NAM winding up stronger than is currently being modeled. We observed a stronger -NAM back in March of 2013, and a truly prolific -NAM back in 2009-10. http://www.cpc.ncep.noaa.gov/products/precip/CWlink/daily_ao_index/ao.shtml 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...

Colder here than yesterday... only 29 right now. Not sure I am losing anything to sublimation either given the frozen nature of the snow cover. Our trees lost their snow in the fog on Monday and now the wind. But nothing has melted on the ground. Sledding is great for the kids.

snow_wizard Posted December 31, 2015 Report Share Posted December 31, 2015 Well, the 00z EPS mean has the 0C 850mb line down into Florida during the 11-15 period. That'd be quite the turnaround. Just because the 0 line is in Florida doesn't necessarily mean it will be overly cold in the NE. In this recent cold period California dropped below zero at 850mb in most places and yet the PNW never went below -7 or so. Right now the Eastern troughs are shown to be transitory.

The GFS and ECMWF agree on tanked EPO and AO at the time the PNA should start to drop again. Look like the WPO may also go negative for the first time in quite a while.

Right now the Eastern troughs are shown to be transitory.There's nothing transitory about this. After January 10th, troughing will be primarily located over the east/southeast for the remainder of winter, minus a potential warm shot during late January. A monstrous +AAM surge is now ongoing, and this momentum will propagate poleward and should supercharge the STJ, preventing any sustained -PNA/-EPO. Late January offers the potential for a relatively quick -EPO shot, though.
