PNW February 2023 Weather Discussion - Meteorological winter finale


Recommended Posts

I'll be dipped.  The snow the ECMWF is showing for King County is exactly like last February.  It actually rotates in from the ENE.

What I mean is that the 0z was not that impressive. From last night wasn’t that great except for southern WA.

00Z run last night showed 5-10 inches across most of the south Sound area... 3 inches at SEA... and 12+ across a good part of the EPSL.     I guess for Bothell it was about the same.

Similar set up to the late January event as well when there was thunderstorms and hail in the Seattle area.

This one right? Is that three at SeaTac? One Op run doesn’t matter much anyways that runs EPS was much better.image.thumb.png.ad420f68a587f117c556337e2068bda9.png

Yes... that was actually c-zone action on Tuesday when the cold air was coming in faster.    The snow on the 00Z run tonight comes in from the east on Wednesday.    Big difference for areas to the south and east of Seattle.

Dude... I am just pointing out last nights ECMWF run was impressively snowy for a good part of the area.   It was not a dud run at all... it had some anafront properties for the area east and south of Seattle.   That is not nitpicking.   But I do see it was about the same for Bothell and that was his perspective.

I think you did ask if I was ok. I am getting little sleeping lol. It’s all cool.

I thought you were mixing up maps again because you referenced the 12Z run but posted the 00Z map... but you clarified.  Just an attempt at a humorous reference to your comment earlier about mixing up maps.  😀

Wasn’t paying much attention earlier this evening. I see SFU is getting dumped on with heavy snow. 

I haven't paid attention to this system either... but the ECMWF shows there might be some snow in the air even in the Seattle area tomorrow morning.

And then 35/22 a couple days later... that is some pothole forming weather! 

There’s a reason we have the worst potholes in the country.

Spring be springy. Oh wait it’s still February..nevermind. 😒

Adding the overrunning snow next weekend on the 00Z ECMWF and you end up with a decently snowy map for the Seattle area when all totaled up.

Unfortunate for further south

Actually many hard freezes in there.   Going to be hard for the trees to bloom with that weather.

EPS has looked similar... no warm weather in sight out here.    Good for the mountains.

Tell that to the cherry blossom & magnolia across the street. :(

There was a very hard crash in spring 2016/17, upper 70s to mid-teens within a couple days. Lots of dead magnolia flowers, but surprisingly everything else just chugged along like nothing happened.

Where are the classic overrunning systems? We need one of those methinks, enough of the cold just slowly moderating.

 

Our Christmas eve sleet/ZR storm 2 months ago was a classic overrunning setup. Had impressive surface cold and strong east winds and an overrunning system. It was 95% of the way there for a classic east wind driven PDX snowstorm. It was all there minus that pesky warm layer around 900-850mb.
