Jesse Posted January 29, 2016 Report Share Posted January 29, 2016 Sure is a dream killer this far removed from the solstice. I think PDX could still easily pull off mid-20s for highs with that kind of airmass. Lower with any cloud cover. Quote Link to comment Share on other sites More sharing options...
High Desert Mat Posted January 30, 2016 Report Share Posted January 30, 2016 What would temps be in pdx with -20 850mb temps in mid February?Mid 20's at best I would assume. Single digits to low teens in my neck of the woods. It would rival what we had here in Redmond during the event two years ago around Feb 10th week. I had highs of 5-6 degrees for almost a week with 34" of snow on the ground Quote Link to comment Share on other sites More sharing options...

BLI snowman Posted January 30, 2016 Report Share Posted January 30, 2016 I want to say 850 temps were only around -13c then though at the peak. Yeah, I think that's about right for PDX. http://mp1.met.psu.edu/~fxg1/NARR/2014/us0205.php With snow and strong CAA there's no reason why Portland couldn't still see a high in the mid 20s or lower this time of the year. It just depends on the setup. Portland pulled off a high of 29 on March 3, 1960 thanks to falling snow, strong east wind, and arctic air to the east.

snow_wizard Posted January 30, 2016 Report Share Posted January 30, 2016 Interesting turn of events on the 18z GFS. Not as outlandish as it may seem with some ensemble support and a strong maritime continent MJO wave strongly supports a significant cold period during week two. It's quite interesting to note the ECMWF ensemble control model has been strongly hinting at a significant cold snap for the NW during week two on many of its runs. The 12z ECMWF also trended westward with the ridge during week two. something to watch for sure. I'm not saying it will happen, but it's not out of the question. 1 Quote Death To Warm Anomalies!

snow_wizard Posted January 30, 2016 Report Share Posted January 30, 2016 I also see the WRF has gotten more bullish on lowland snow chances early next week. Pretty favorable trends even in the shorter term. One thing I will say for sure is it appears a major Arctic blast is going to effect parts of the United States during week two. If by some chance it hits here it would be tremendously against Nino climo. that would make it all the more sweet. Off the top of my head I can't think of a single significant Feb cold snap during a Nino of any strength. 1 Quote Death To Warm Anomalies!

Off the top of my head I can't think of a single significant Feb cold snap during a Nino of any strength.Yeah, someone is going to get crushed in February. The upcoming wave activity looks stronger, and different in nature, compared to the January event. The upcoming round is largely a result of (initially) destructive intraseasonal forcing under the seasonally progressive antecedent forcing (ENSO). Even without the destructive interference, a retrogression of the NPAC vortex would occur for the aforementioned reasons. The January event evolved out of constructive intraseasonal interference, timed perfectly to allow for a dual Eurasian/North Pacific wavebreak that fought the PV.

Since ENSO data started in 1871, only February 1995, February 1905, and February 1900 fit the bill and managed subfreezing highs at Portland or Seattle with an El Nino. That's 3 times in 140 years. It's obviously about 100% more common in a Nina February. Quote Link to comment Share on other sites More sharing options...
snow_wizard Posted January 30, 2016 Report Share Posted January 30, 2016 This really makes me suspicious of a big Western ridge. This MJO placement has brought troughs every time it has happened this winter, and normally does in other years also. also very destructive to El Nino. Quote Death To Warm Anomalies!

Phil Posted January 30, 2016 Report Share Posted January 30, 2016 Careful with those phase diagrams, Jim. They're easily contaminated by stagnant forcing, off-equator forcing, as well as CCKW activity. Also, intraseasonal/MJO forcing will affect the mid-latitude circulations differently depending on the ENSO/QBO/PV state, particularly in a year as anomalous as this one, FWIW.

I have made peace even in an increasingly wet regime this decade. Looking back at calendar years for SEA (that is how its shown on WRCC): -10 year period from 2000-2009 had only 1 year above 40 inches of precipitation. -Since 2009 there has been 4 out of 6 years with more than 40 inches of precipitation... including 48+ inches in 2012 and 2014. For comparison... from 1960-1990 there was only 8 years with more than 40 inches in a 30 year span. Its been a very wet decade here. Probably a sign of things to come with a warming climate.
