Phil Posted October 1, 2018 Report Share Posted October 1, 2018 Looks like I’ll be living vicariously through you guys for the next several weeks at least. Funny how, during the autumn, a poleward displaced ITCZ/Hadley Cell network in a niño forcing regime can emulate a niña in the extratropics. It’s one of those bizarre overlaps in the spatial nature of the seasonal cycle. Recall we saw something similar the late autumn/early winter during the super niño of 2015/16.

Phil Posted October 1, 2018 Report Share Posted October 1, 2018 2015 was a near record warm October for many parts of the west. Like 2014.The pattern I’m referring to occurred in Nov/Dec 2015, when the subseasonal cyclicality of AAM was more structurally analogous to today. The structure will almost never match perfectly, though.

Phil Posted October 1, 2018 Report Share Posted October 1, 2018 Then why do you keep bringing up 2014-15 and 2015-16. Back to back duds.I’ve seldom discussed 2015/16 in the context of winter analogs..and there was an Arctic blast in Nov 2014. Just because I “talk” about certain years doesn’t mean that I’m relying on them as analogs. No two analogs are alike...you can’t use analogs to predict the weather on a week to week basis. You use analogs to isolate homogenous low frequency tendencies, from which you can (possibly) extract the likelihood of particular weather/climate events occurring in a particular region, or timeframe.

In reality... there should probably be some other small areas of purple in elevated spots out here like my area with orographic enhancement with the persistent c-zones.

Which was amazing as it was timed around the same time as the 1955 blast. The November 2014 blast was one of the greatest early season cold waves on record for parts of the West. - Boise saw three straight lows below 6 degrees, the earliest they've ever seen that.- Casper, WY had their earliest single digit highs on record and set their all-time coldest temperature for November with -27.- Cheyenne, WY had a high of 1, by far the earliest they've had a day that cold and their second coldest high on record for November.- Boulder saw a low of -11, by far their coldest that early and second coldest temp ever in November- DEN's high of 5 and low of -10 were both the coldest on record for November Overall that month, though, the main cold was centered in the Upper Midwest.

The Arlington to Monroe area was the wettest relative to normal of any area in the western lowlands, and that's reflected well on the map. It's never going to take into account every little micro-climate like yours. Plus, the September average rainfall for your exact location could easily be over 5".

Front Ranger Posted October 1, 2018 Report Share Posted October 1, 2018 Going back to the question of whether seeing cold patterns now is a good or bad thing...I think history would indicate it's more of a good thing, especially with weak ENSO. A lot of winters that went on to be good to great for the PNW/West had significant cold events in the mid Sep to mid October period, with all different ENSO backgrounds. But many non-Nina years that ended up peaking early or just being terrible had very little cold early in the fall (1991, 2002, 2014, 1993, 1952, 1980, 1987, 1957).

Phil Posted October 1, 2018 Report Share Posted October 1, 2018 Trough just sits and sits...We need this in winter. Well, the wavenumber would never be this high during the winter (Aleutian Low + GOA ridge + western trough can only occur during the summer and autumn). So technically speaking “this” particular pattern is unlikely to repeat itself.

You were probably very close to normal, even if that map technically show you a little above. Sandpoint had 1.41", which is slightly below normal for them. Quote A forum for the end of the world.
