A friend that lives on Camano Island is reporting hail.

The false ridging period was really a pattern change to wet... took the models awhile to figure it out.   Probably going to see a decent run of rainy days which is not too unusual for April.   

Today's high in Seattle was the normal high for January 11th.    

[MossMan]

Hailing. 

[jcmcgaffey]

Crazy weather over in South Dakota. Currently a blizzard warning for up to 30” of snow and 55mph winds while next week highs in the 70s. 

[The Blob]

The only rumbles I've heard today are the wheels o'trash going to the street. 

[TT-SEA]

Side note... what is likely driving this is the MJO going back to into phase 7 which clearly favors troughing in the PNW in April.   This was mentioned last week in Ag Weather update and again today.   When the models are not in sync with the MJO they tend to correct as it gets closer.   This can go both ways of course.

Forgot to post this picture I took at 8:30 tonight. 

[SilverFallsAndrew]

Incredible to see how consistent the precip has been over the mountains. Amazing storm for the higher elevations. 

[ShawniganLake]

Looks like an outflow boundary on radar, especially to the south and east of that cell in the central sound

 

[Slushy Inch]

Score! Lightning! Was not expected first lightning of the year to be at 11:30 at night. So much for diurnally triggered storms.

The way this trough hung west a little bit  as it dropped south I knew there be shower and convergence zone potential for several days. Little stronger and it would have been very impressive. 

[Gradient Keeper]

Uhhhhhhh........ 00z runs suck. Max temps: GFS 52. Euro 55.

On the bright side, more potential for instability!

If we're going to remain in this repetitive troughing pattern as long as we can score some good convection, hail, t-storms, nice cloud structure, okay. Otherwise I'm not not a fan of rain and below average temperatures.

Think Spring Convective Showers/T-Storms, or Sunshine/Warmer Weather.

Agreed!

[Meatyorologist]

As a survivor of the 2013-2016 permaridge, I can assure you I am fine with this troughing period going on for a whiiiiiiile longer...

[Cold Snap]

Currently snowing!

 

 

[Slushy Inch]

Rinse and repeat. It never ends. Good for mountain snow and convection.

I don’t know if you noticed, there was just some lightning west of you.

feels like an east coast permaridge now. 🫤 It’s as persistent as anything I can remember in my lifetime.

It's been a while since the PNW has seen troughing like this with a dying La Niña. March 2009 maybe?

Would be nice to have this troughing branch into the summer. Any indications on what we might see here yet? Do the tea leaves spell out any favorable acronyms?

[Meatyorologist]

ICON and GEM go zonal in the mid-long range. Opens the door to unseasonable windstorms and stout frontal precipitation. And potentially a more pronounced N/S temp and precip gradient.

I’ve just heard that Summer looks warmer and drier at this point.

A constant to rely on these days.

Not this year. Slightly below average temps and few heatwaves.

[Gradient Keeper]

This had to be hail melting in the rain gauge? or something.

[Cold Snap]

Looks like a convergence zone is forming!

Has been going on for some time now. Still seeing snow?

Maybe 2012? Thing about 2009 is that it was evolving into a modoki niño, which this event won’t be (assuming it happens). If you don’t count 2012, you have to look all the way back to the previous cold phase, I believe.

I do have a hunch about something, but I’d rather not say anything right now.  Need to test the theory first, lest I jinx it.

Yes but it’s not really sticking much even to grassy surfaces. Up at redmond ridge which is about just over 100 feet higher in elevation than me is a whole different story.

[Cold Snap]

And in 10 minutes the roads are now completely covered.

I need to move back to a place at 500 feet!

[Gradient Keeper]

What's the best analog up to this point from Jan 1st to April 1st. 2012? or....

I honestly would say that a pretty good one except Puget sound had a significant snow and ice event that Jan. And I’m pretty sure MBY got more snow that march and in multiple events while this past march all of mine was from one event. Solid dusting on everything now though it’s a pretty slushy dusting as everything isn’t turning that white but there’s a layer of slush over it.

[Cold Snap]

Redmond ridge is nuts right now. That place can do so much better than me sometimes especially in elevation dependent setups.

That's unbelievable. It looks like it's December 4th, not April 4th!

[Cold Snap]

Picked up a very slushy 0.25” so far. Redmond ridge probably has around 2 inches based on the cams.

[MR.SNOWMIZER]

33 degrees and DUMPING snow

[MR.SNOWMIZER]

Wtf is going in lol, if this pattern had set up in December like we've had the last 6 weeks it would of been a winter to remember! It's been a great winter for a few places though but the has been a crazy long stretch of below temps.

[MR.SNOWMIZER]

Trees are cars have a light coating, down to 32.7 now.

[ShawniganLake]

Dusting of snow here this morning on top of yesterdays hail which is still on the ground.  

[SnowWillarrive]

Woke up to a dusting of snow. Snowed two days in a row here. 

Crazy how many days this season had flakes flying.
