Phil Posted December 30, 2020 Report Share Posted December 30, 2020 Stuff like this matters, and it’s why the next 10 days are so important. 18z GFS vs 00z GFS. Both major SSW events but very different wave positions/structures. (Not saying it’s bad or good or anything..just observing).

Well, it’s a weather forum in the midst of a rather (so far)uneventful winter, so I’m wondering what else you’d prefer to talk about? Endless posts about how it’s 41 and raining in the “swamp” or those that suggest Eugene is a snow-deprived wasteland, derelict and forgotten by Mother Nature? Or perhaps mocking “we’re fuc$&!” (MLK!) posts after every bad run? I personally enjoy the speculative, sometimes-bordering-on creative analysis in these moments. Pretty boring place otherwise. Keep it up, I say. Not to mention the naysayers would have no identity otherwise. Just like me. 5 Quote Link to comment Share on other sites More sharing options...

Meatyorologist Posted December 30, 2020 Report Share Posted December 30, 2020 "Half a mile underground in New Zealand, a starry sky twinkles. Or so these glow worms want you to think. The Waitomo Caves are home to bioluminescent larvae, destined to become the much less sparkly Arachnocampa luminosa gnat. Like fireflies, these worms glow using chemical reactions. Unlike fireflies, they use their powers for hunting, not finding love. The lights confuse moths — which use the real night sky to navigate — and their wings get tangled in the gooey strings of beads dangled by the worms on the cave ceiling. The worm then reels the disoriented and sticky moth in. Slime seeps into its breathing holes, and it's still alive when the worm begins to feed." 3 2 Quote Weather stats for MBY Snowfall: -Total snowfall since joining: 50.25" -2018-19: 21" -2019-20: 2.5" -2020-21: 13" -2021-22: 8.75" -2022-23: 5.75" -2023-24*: 0.25" -Most recent snowfall: 0.25”; January 17th, 2024 -Largest snowfall (single storm): 8.5"; February 12-13, 2021 -Largest snow depth: 14"; 1:30am February 12th, 2019 Temperatures: -Warmest: 109F; June 28th, 2021 -Coldest: 13F; December 27th, 2021 -Phreeze Count 2023-24: 31 Link to comment Share on other sites More sharing options...

But lots do, including the CPC, many private companies who need long range forecasts to make business decisions, etc. And it wouldn't be very fun if all we looked at was the 7 day. And, despite what you think, just about everyone on here knows how unreliable it can be. so we are more concerned about trends, ensembles, etc. 4 Quote Link to comment Share on other sites More sharing options...

AbbyJr Posted December 30, 2020 Report Share Posted December 30, 2020 Its been mentioned on here before but I'll mention it again. That is, it seems that many back east seem to think that every SSW event is going to favour them for arctic air. I'll add that its a bit frustrating that its so hard to find any commentary on how the upcoming SSW event may impact the NW US. Rather, its always talk about how it could send major cold down into the NE US. The question is whether or not there is any data to back up the idea that SSW's always favour the east? Perhaps there are just more weather enthusiasts and commentators in the east and at least some of them have a cold bias? To be fair, those back east could say that we have a cold bias in the PNW.

What are all of your thoughts? Arctic air invading the US has a general tendency to favor the east, so theoretically they’re right. SSW’s are a grab bag phenomenon. It shakes the snowglobe in ways that can’t be directly attributed to nearly the level of continuous progression you’d like. Cold air will be on the move, which is a good thing for everyone who likes cold air. 5 1 Quote My preferences can beat up your preferences’ dad.

Someone asked Judah Cohen if the SSW could affect the PNW and he said the PNW is only affected by the Pacific Ocean. To be honest, that statement is laughable. I'm not saying he's not an expert in his field, but rather that its quite strange to suggest that the Pacific Ocean is the only factor in our climate and weather patterns. Does he not realize that February 1989 and February 2019 likely would have played out completely different in the PNW absent of a SSW event? I'm sure there are other examples too. Fact is that there are so many different factors. There have of course been SSW's that have not led to a PNW arctic blast but those were likely during +ENSO years and or without a favourable QBO state. But wait, are we sure he actually said that? Looking at this tweet, he does mention Western cold from a SSW. Quote Link to comment Share on other sites More sharing options...

Perhaps there are just more weather enthusiasts and commentators in the east and at least some of them have a cold bias? I think it's just that SSW makes it much easier for arctic air to push South in general and since the East has no mountains between them and the Arctic, it will always be much easier for them to get hit. SSW still opens up possibilities here too though if we can get a block around 150 latitude.

What are all of your thoughts? Yeah that’s east coast weenie mythology. There’s wild variability from event to event, of course, but when you look at it in aggregate, a higher proportion west coast cold outbreaks feature amplified surf/disrupted TPVs than east coast events, and just as many occur during/after SSWings as those in the East. Which could simply reflect the fact the NW US needs more of a meridional component to receive arctic air than the East. In the end, polar blocking increases the odds of middle latitude cold anomalies almost equally at both coasts. ENSO/QBO modulates that to an extent. 2 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...
