The 4/9-16 period was the coldest on record at KSEA

Colder than the average temperature for December (42.0F) or January (42.8F)! Although not quite as cold as the coldest average week in SEA (December 19-26 with 41.6F).

Break it first.

Sorry for ruining the mood around here earlier. I was in a bad mood at that time for unrelated reasons and I’ve logged off for a few hours to get up, and do some other, more productive stuff. Next time I just gotta go outside, do something else, and clear my head. And if I don’t - tell me to!

I really do learn a lot around here... gotta thank you guys for putting up with me.

Don't remember whether this return to Nina conditions was expected. 

Impressive winds tonight. Huge limb came down on some power lines on a SW-exposed ridge crest in N. Seattle.

If you do it’ll snow again.

Possibly the most prolific Niña background state since 1999. Doesn’t want to yield an inch right now.

You’re your own worst critic sometimes. I didn’t see anything from you necessitating an apology.

We'll need to wait and see what Tom Brady winter decides to do.

Hit 52 today, down to 38 now. 0.57” of rain.

Over 4” of precip on the month here now after 1/2” today.  This is turning into a wet April, although I doubt we catch 2018, that was a very wet month here.  Hopefully we see a nice rebound to some sunny warmer weather in May like we did that year.

Early May could be warm. So maybe it’ll start out that way?

That said, the ENSO situation is so vastly different from 2018. I have a hard time believing we’ll be matching with that year very often, save the typical windows of high frequency overlap.

Only 1.54" here so far which means I'm on track to get only about 80% of normal. Although today's 0.27" did bump me over last year's total for the month and it looks like maybe I could get close to normal if the long range is correct.

[Meatyorologist]

Wow, the 00z NAM is going for some serious convective business in western oregon Wednesday. Whether this environment truly materializes remains to be seen but at face value, the temperature, moisture, shear, instability, and storm motion are dead ringers for the 4/5/1972 tornado outbreak in the Willamette Valley. Hell, even the time of year matches.

[Meatyorologist]

500mb pattern over North America is very, very close, particularly over western OR. Isopleths are parallel at an identical angle, and pretty much spot on in value and gradient.

Wow! I’m probably 15min away from you and I am way past you on the month with over 4”.

I think in general you're about 2x me, so it makes sense. I average ~34-37" a year and I think you average over 60" don't you?

[SilverFallsAndrew]

Chase day on Wednesday?!

In the meantime...

Snyder has his eyes on it I'm sure.

PDX discussion suggests at nearly continuous shots at thunderstorms through the week.

This April is certainly much, much more exciting than ones we've seen in this decade prior.

Old man winter refuses to leave North Dakota. This is insane.

 

[TigerWoodsLibido]

41F and cloudy.

Interesting how dominating the teleconnection between the PV and NPAC/PNW has become in recent years. It was always there, but not necessarily this coherent or overwhelming.

There were plenty of winters in the 1980s/90s that delivered major cold to the NW absent any demolition of the PV. But in recent years, almost every winter with a strong vortex has torched up there, and every SSW has been followed by anomalous cold in the West.

I think these dynamic relationships evolve with respect to time. It used to be the Eastern US and Europe that saw the most direct effects from SSW events, but now that appears to have shifted such that the dynamic linkage is stronger in Western North America. At least for the time being.

I’d always said that SSW events were important for weather/climate dynamics across the NH, including the NW (as opposed to the myth that they only affected the E-US) but it’s still fascinating to watch it play out in real time.

The climate shift in 2013 (seemingly triggered by the SSW in winter 2012/13) is what ultimately woke me up to their importance. I believe there’s evidence that the late 1940s climate instability (and eventual transition to -PNA/-PDO) also began with a series of SSW/dynamic FW events and their effects on tropical convection and the ENSO/IPWP system.

Though it could be both were a symptom of larger scale, low frequency changes in the system state. Can’t know for sure.

The climate shift in 2013 is what seems to have led to the terrible drought conditions and dramatically increased fire activity in northern California over this last decade. I am hoping that this pattern shifts again so that California and other areas of the West once again get some wetter winters to alleviate the drought conditions in the near future!

The global temperature anomaly has dropped to zero on the 1979-2000 baseline.

North America carrying the weight in the northern hemisphere. Poor SW though, they can't catch a break for their own lives

hmmmmm

Thread by Michael Ventrice. Specifically mentions the East, but this has affected the West as well (obviously).

Snowiest winter since 2007/08 in Toronto.

A lot of La Niña/-PDO years in the low pass analogs.

[TacomaWaWx]

Got down to 40 this morning. 0.30” of rain since midnight and 2.51” so far this month. 

[SilverFallsAndrew]

36 degrees. 0.37” since midnight. 6.77” on the month. 

[Blizzard777]

Hopefully some T-storms ️ and fun showers today!

40* 

.28 precipitation overnight 2.56 for the month

Not sure if this will work, and if it doesn't checkout the Whatcom Weather page on FB, looks like there was a small waterspout on Lake Samish (just south of Bellingham) yesterday:

Washington passes still getting pounded with snow.  Pretty amazing week and half up there especially for this time of year.

2007-2008 winter is a good match for us. We had an insane amount of snow in a 5 week period that winter and that was it. This winter we had an insane amount of snow in a 3 week period and that was it for winter.

I see that Bismarck just set the record for the snowiest April ever at 21.9 inches so far... barely beating out 2013 at 21.8
