All these records being smashed..maybe the Hunga Tonga eruption actually has reshuffled the deck somehow? :lol: 

Something like 8% of the total H2O mass above 100mb came directly from the eruption. Almost unimaginable.

It's possible, it could also be we were a bit "due" for a cooler than average spring, which makes sense given the -ENSO background state.

Agreed.

Friends of ours that lives at Lake Chelan posted a very snowy picture of their backyard on FB and wished they had held off on planting several new plants. 
Up here at home it’s been dry and cloudy. Had a low of 34. Might mow this afternoon.

Interesting. Basically says since the volcano erupted in the Southern Hemisphere, there isn't a mechanism for it to have much impact on the Northern Hemisphere. Volcanoes that erupt near the equator have a bigger impact globally and Northern ones impact us more.

Yeah the background state is as impressive as anything observed this century and would favor a cooler spring regime regardless.

But this pattern appears to be as impressive as anything observed since the end of the LIA. Could simply be the perfect alignment of variables on the subseasonal scale. Well within the realm of possibility. And perhaps the more likely explanation.

But it also wouldn’t surprise me if the immense injection of H2O (and other substances) into the stratosphere may have somehow affected the tropical-subtropical convection and circulation. Some of it even reached the mesosphere.

Almost 60km high. Blows Pinatubo out of the water..literally.

Problem is that only refers to the SO2 content (which is responsible for cooling the lower troposphere when injected into the stratosphere). 

In this case there was an insane amount of water vapor injected into the stratosphere (and even the mesosphere!) which may not cool the climate, but may drastically impact the structure of radiative/thermal fluxes and perturb tropical convection and global circulation. Perhaps even more significantly than SO2 alone would.

We’ve never had a massive phreatic eruption in the satellite era before, so this is a live experiment, of sorts.

That is nonsense and goes against everything we know about the Brewer Dobson Circulation and thermal-radiative balance (esp given the eruption was near the equator and roughly 20% of the ejected material is already in the NH).

It could be the eruption has a net warming effect on the climate when it’s all said and done. But the idea that an eruption just south of the equator (during boreal winter especially) cannot affect the NH is absurd.

The last real cold April in the region was 2011. Mother nature’s probably just tipping the scales back.

April 2017 was more incessantly wet and cloudy than it was cold, April 2011 was more of a continental nature. If anything 2011 was probably more “pleasant” outdoors, at least around here.

I remember spring 2011 being exceptionally chilly, and a lot of cloud cover overall. Interesting we also had the late February cold snap in 2011, though that was a bit more pronounced than the one this year.

Tim mentioned the foliage has stopped progressing in his area. I haven't noticed that as much, because things are still fairly dormant up here, there are some leaves coming in on the alders, and vine maple are budding, but it will be interesting to watch the progression of the field grasses. Because I have grazing livestock that is always something I pay a close attention to. 

We bought the place in 2011, and I remember clearly how short the grass was when I first visited the home in early June. I have never seen it close to that short in any of the years since, and some of the understory vegetation had also not fully leafed out yet. Usually that's a process which occurs very rapidly in late April and early May. Will be interesting to see if this cold snap has any delaying effects on the process this year.

I don’t remember spring 2011 all that well because I was a kid then and I kind of still am. Was it very cloudy on the valley floor particularly? I remember 2012 being rainy though.

I get why Tim and Mossman complain about spring troughing... they’re in an NW flow orographic lift area. Very different geography. Hillsboro and Corvallis are both shadowed so even the troughing here still often produces “nice” weather. Just need an extra layer on is all.

You may be correct on the moisture being generally wetter in 2017. April 2011 totaled almost no snow in K-Falls, so quite a bit different than 2012/2017. though it did graupel a heckuva lot in Spring 2011 on those afternoons with spotty showers all over the place.

I notice there's fewer references to Spring 2010 after it started getting cold. I still lived in NW Oregon at the time and don't remember hating that season really. Even tho it had an insanely wet May, it was more temperate than the one's we've been discussing lately?

March was extremely cloudy. Salem had measurable rain on 28 of 31 days. 

April it was more showery. A lot of days like yesterday and today in the valley. 

May was also damp, and very gloomy by May standards here.

some short range models hinting at a couple inches tonight.  NWS made this statement a couple hours ago

 

The not so surprising, but very difficult to forecast, situation 
  where a very small scale circulation moving through the cold and 
  conditionally unstable airmass over Eastern Washington and North 
  Idaho has manifested in the form of heavy snow in the Wenatchee  
  area this morning. Storm reports reporting localized snow  
  accumulations of up to 16 inches near East Wenatchee, Washington  
  as of 830 AM this morning are verifying this morning. The  
  circulation is showing signs of weakening and slowly moving  
  northwest away from the area. With the expectation that pavement  
  temperatures will warm and at some time should at least inhibit,  
  if not work against, accumulation we will continue to mark the  
  activity of the snowfall associated with this small scale  
  circulation with a nowcast. Where and when could the next small  
  scale circulation make use of the cold conditionally unstable  
  airmass and produce a localized intense snowfall? In addition to a 
  circulation moving northeast that looks to move through Grant and 
  Adams county later this morning and early afternoon short term  
  Ensembles suggest such a circulation could approach the Spokane  
  and Coeur d`Alene area tonight into tomorrow morning and possibly  
  produce similar results in Southern Spokane and Southern Kootenai  
  Counties and further southward into parts of Whitman, Benewah,  
  Latah, and Shoshone counties (but north of Moscow/Pullman area)  
  with the probability of exceeding 4 inches of snowfall in 12 hours 
  between 5 PM PDT tonight and 5 AM PDT Friday morning is running  
  between 30 and 40 percent. /Pelatti

I was living in Oklahoma at the time, I do remember a lot of comments on Mark's blog and this forum around that time around how gloomy that spring was. I do notice some of Silver Falls record Min/maxes are from late April-June 2011. Looks like May 2010 had 5 sub-50 highs at Silver Falls and a monthly average high of only 55. June had a high of 48 on like the 20th... That's pretty impressive. 

May/June 2010 were much wetter than 2011. May 2011 was slightly cooler than 2010, but June 2010 was slightly cooler than 2011. 

Also checked on April, 2011 is the coldest April on record, 2010 was just a little below average, but was extremely wet.

I love mowing... Haven't had a chance yet... Part of that is probably due to over expanding our duck flock... They browse through the front yard at night and keep the lawn at about 1-2" in length.

Hmmm... GFS ensemble is trending cooler. 

I remember when the GFS/GEFS was projecting a big ridge for this timeframe (and a weird backtracking TPV). Oops.

I’ll never trust that model. Could be 100% correct, but the EPS/Canadian ensembles have lots of divergent solutions in the long range. Looks like a period of low predictability coming up late this month into early May (which is when MJO/tropical forcing would favor a warmer (or at least a less cold) upper level pattern in the NW).

Could be a very short hiatus, though. 🥶

MJO about to loop through the WPAC it looks like. 

Shows how strong the Niña background state is. It’s fighting back hard. If we had the background state from 2020/21, we’d probably have a massive ridge forecast.

Correct re: WPAC MJO, esp in Jul/Aug/Sep.

That said, some caution should be exercised with those unfiltered phase diagrams, as the background state, ERWs, and higher frequency waves (CCKWs, etc) are all projected onto there. So sorting out which is which, and the degree/nature of forcing(s) from each, is impossible without looking at VP200/OLR hovmoller plots or something adjacent to that.
