Big time lightning here on Snoqualmie ridge at the golf tourney. This photo from my golf cart. It screwed up my phone when taking  

How many Mississippi's between the flash and the boom?  I've had once instance of it being almost simultaneous while outside.  Not a good feeling.

[Phishy Wx]

Started Thundering about 5 min ago.  Storms starting to light up the radar

got one forming just South of me

 

[RentonHill]

@SouthHillFrosty i bet that house you looked at is getting lit up or is about to. You gonna buy it???

[the_convergence_zone]

So, is the NWS going to issue a flash flood warning for Baring? It looks like there is a cell basically right on top of the Bolt Creek burn scar. 

[TacomaWx]

Marine push underway to the west…Shelton down to 79 after maxing out at 90. Marine push could trigger some convection as it moves inland. Just hit 89 here a new record for May and still time to hit 90. 

[T-Town]

89 here now. As long as we’re in the neighborhood we might as well hit 90. 

Update - 90 now.

I thought the temp would cap out with clouds but temps been rising faster with cloud cover.

I’ve been stuck at 86 for a few hours now under consistent partial cloud cover

[Ken in Wood Village]

There is a lot of activity now. I'm home. Sorry for the timer. I'm cooking something...lol.

[TT-SEA]

Managed 5 minutes of large rain drops that barely wet the driveway with a cell that formed right overhead.   Lots blue sky to the east now.    Good news is there was no flash flooding with that cell.  

[RentonHill]

Time to sit outside with a beer and wait

 

[Phishy Wx]

decent thundershower cut just west of me.  still got about .2 in about 10 min.  pouring for a minute or two so hard you could barely see across the street.  still raining in various intensities 

[SilverFallsAndrew]

Definitely a complete bust in Oregon per the usual. 

GFS was decent again. 

[the_convergence_zone]

It looks like there's going to be a spectacular lightning show around sunset if the HRRR is right. And the HRRR has done a pretty good job with this event so far. 

I'll be impressed if I get a single drop of rain, I think the activity is going to stay largely south and east of Seattle. 

[Ken in Wood Village]

I wouldn't want to be driving along I-5 near Longview. Those storms will be producing a lot of rain. 

[TT-SEA]

Looks like the MJO has basically ground to halt for at least a couple weeks after cruising through almost all the phases since late April.   Not sure what that means... but phase 7 tends to be warm from May-July.  

 

[Phishy Wx]

poured again, with the occasional piece of pea sized hail.  that lasted about 2 min.  now dead calm.  temp dropped to 72

[Cold Snap]

83.8 now. Feels pretty muggy outside.

[Phishy Wx]

now down to 68.  I figure the sun will probably come back out and it'll become a steambath soon

[SilverFallsAndrew]

Nice to see the GFS ensemble mean staying right around climo from the 21st through the end of the run. NOT SURE WHAT IT MEANS, but usually average 850mb temps translate to near average temps, though certain specific climological or geographical factors could come into play!

[Ken in Wood Village]

This storm is coming straight at me. That's if it holds together.

I think Portland metro still has a chance for something this evening.

It's looking stormy out in that area!! Naw didn't end up buying it, there was a couple issues with the land. Still on the hunt! 

[Doinko]

Looks like some lightning in Camas?

[TT-SEA]

Completely quiet to the east now... doesn't seem like there is another round coming. 

[Doinko]

That storm in sw Washington looks strong

 

[TacomaWx]

Storms have had a hard time getting off the terrain so far…but it’s early still.

Marine pushy out there gradients are gonna flip onshore soon

[icyasf]

My locations microclimate is always fascinating to me. We always get in on marine pushes so it’s 73 here while everywhere else in the valley it’s in the mid 80s still.

I think this statement is for this thunderstorm. It looks really nasty 

[Deweydog]

THUNDER

[Eugene-5SW]

No convection here, but onshore breezes have cooled temps off from 88º to 82º. Feels nice.

[Doinko]

Hopefully it lasts on the way here, but it's really strong right now

 

[Doinko]

Just saw some distant lightning

Hoping it can survive on its way there!

 

[Blizzard777]

Time lapse but I took a nap during mine

Looking towards Thurston county (The Cliff House Restaurant is where I took the video)  Saw a few lighting strikes 

[Deweydog]

BREEZY and RUMBLY!

[SouthHillFrosty]

This event is already being called a bust on twitter lol

Ouch….even in the Midwest during my little storm chasing adventures the storms didn’t pan out…Sad Panda 

[SnowySeeker50]

The sun is back out and the temp has risen to 89 degrees.

[T-Town]

Wind has switched to southerly here. Marine push has arrived.  

[MossMan]

All is quiet up here still. Temp down to 79 from a high of 89. Time to BBQ! Did have some cool looking skies up in Mt Vernon and driving back home just a bit ago.

Yeah I’m seeing some tweets lol but it honestly does not look promising for areas north of Tacoma.

Pretty strong band moving through down south.
