I guess I was fortunate to get the one flash/rumble and .02" of rain here from a split second downpour. At least this month won't be a total shutout now.

I also saw multiple distant flashes from the cell that faded near McMinnville and had some light rain too. Was hoping for something more here but I'm glad that Salem to Eugene saw something good.

Almost all of the thunderstorm activity ended up offshore in WA.  Kind of a waste, but at least it's good news for fires.

A fish storm as they call it. It's just hard to get any good widespread precipitation here west of the Cascades from mid July to mid August.

I've heard this thrown around before, but I'm not sure if marine pushes can even really be a trigger. They exist at such a shallow portion of the atmosphere and the amount of air they displace vertically is pretty negligible. In reality I think marine pushes just coincide with larger scale upper level disturbances, which actually do cause lift a meaningful scale and at the middle levels of the atmosphere where storms do end up firing off. Upper level disturbances trigger convection, as well as create the pressure gradients at the sfc necessary for marine intrusions; hence the spurious correlation between marine pushes and convection.

They can be a trigger if there’s a cap in place without a sufficiently strong forcing mechanism. Similar to how outflow boundaries often spark new storms.

Woke up to sounds of heavy rain and thunder around 20 minutes ago in Fife and the power went out too! 

Aaaaand back to sleep. M’s game last night wore me down. 😁😴

So erie out there. The sky is threatening to split open, and yet there is no sign at all of anything when you look up. The marine layer is completely shrouding this midlevel convection. People are walking around downtown like nothing is out of the ordinary, they have no idea.

Heavy gully washer and probably close to 100 strikes this morning some very close. Will post photos later still ongoing. 

Wow!

And to think that a couple hours ago it seemed like you had been completely missed.    What a turn around.

I mean I guess, but our thunderstorm setups are never that tenuous. You are used to sfc based diurnal setups, where even smokestacks have the ability to ignite convection. Out here it's pretty much always midlevel convection setups resulting from differential advection aloft, with bulky caps that need strong systemic lift to break. A few hundred to a few thousand feet of marine trickling isn't going to do that.

Looks like a defined line of activity is beginning to form due to lateral shear over the Sound. Actually supports some kind of organization, particularly north of Seattle. Everett should be on the lookout. Seattle will continue to get clipped by this too.

Was just going to mention that it looks like there is some development out here now.    Watching for something explode like it did farther south earlier this morning.    Unfortunately its impossible to watch from the ground because its foggy here.

Just drove around to see if I could get out of the fog and see above the low clouds... AM radio is crackling like crazy and I think 710 ESPN just got knocked off the air.
