BLI snowman Posted October 31, 2017 Report Share Posted October 31, 2017 I could actually buy a milder winter overall with a stronger stand alone arctic airmass or two if anything.

umadbro Posted October 31, 2017 Report Share Posted October 31, 2017 On top of everything else I have liked about the 6 weeks the record or near record warmth the past few days is a feature that almost always leads to cold winters also. The evidence just keeps mounting. Looking at late October / early November record highs for Landsburg we get. 1921 - Really good winter1944 - The only total loser of the bunch1949 - We all know...1958 - Good January blast and snow in Feb1962 - Very cold January1965 - White Christmas for Seattle and a snowy winter for Seattle.1970 - Good solid winter for most areas2006 - Good late November blast and a great January for the Seattle area2010 - Wicked November blast, wicked late Feb blast, and a near miss huge snowstorm in January. bolded years were cold ENSOHow many were back,to back weak la ninas?

VancouverIslandSouth Posted October 31, 2017 Report Share Posted October 31, 2017 We could see a situation where an AR may transition to snow before the precip runs out. Those are fun! December 1996 also featured some chilly weather in the preceding November. Quote Link to comment Share on other sites More sharing options...
VancouverIslandSouth Posted October 31, 2017 Report Share Posted October 31, 2017 I think the WRF may be bringing the cold air in too fast, which is pretty common. The 12Z showed 1 to 2 feet of snow across SE Vancouver Island on Friday. In reality, best case scenario is probably 1-2” of wet snow as the moisture pulls off to the south. Looks like it's going to be highly elevation dependent and it's getting lost in resolution there. The 1 1/3 km resolution won't look anything like that. Still I think Friday morning has a decent shot at being snow. The timing is good for snow to start the day, but it will be hard pressed to stick around. Also, looks like you may get your first frost tonight. Even here the winds have died down and the air is much drier. Currently 48F. Quote Link to comment Share on other sites More sharing options...

I think this one will have more generalized cold than last winter and not as wet. IMO everything is aligned more perfectly for a cold winter than any since at least the mid 1980s. I will say my NPS index strongly indicates at least one major blast so you could be right about that aspect of it.

I'm not sure the Willamette Valley has ever had 100 days with sub-freezing temps in a given winter since records were kept. I'm sure there have been plenty of those days in a year but even last winter, which was the coldest since I moved here in 1989, only had some 50 days with sub-freezing temps at most.

Front Ranger Posted October 31, 2017 Report Share Posted October 31, 2017 Very cold winter in the works. The incredible lack of low pressure over the NE Pacific for the last several weeks is shown to continue for a long time to come. Analogs to this suggest a great winter coming. I'm leaning more toward a winter that features long frequent stretches of cold weather and drier than normal instead of shorter lived and more intense Arctic blasts, although a couple of sharp cold waves are pretty likely. Winters that would fall into the group of what I'm currently thinking would be ones like 1916-17, 1948-49, 1984-85, 1992-93, etc. All I know is something is up this season. One caveat to this is the possibility of a wetter winter that would be made up of short lived AR events that could provide significant precip in spite of much of the winter being on the drier side. Last winter fit that bill pretty well through early February. Quote A forum for the end of the world. Link to comment Share on other sites More sharing options...

wx_statman Posted October 31, 2017 Report Share Posted October 31, 2017 FWIW, we're overdue for some legitimate CAA at the mid-levels. Horse Creek, a favorite RAWS site of mine at 3,400 feet as it sits in the thermal belt during heat ridges and also represents mid-level CAA during the winter, hasn't seen a maximum below 20 since 2/5/2014, when the high was 18. The lowest since were a pair of 21's on January 3 & 4 last winter. This location hasn't seen a maximum below 15 since 12/15/2008, which had a high of 11. A single digit maximum hasn't happened since 8 degrees on 12/20/1998. For comparison, the upper level beasts of February 1989 and December 1990 produced maximums of -3 (on 2/3/1989) and 1 (on 12/20/1990). 3 Quote Link to comment Share on other sites More sharing options...
