Seattle

Nothing, ironically the dewpoint has dropped back down to 9 with this supposed band! It's 25.5 and the wind is continued light out of the east.

PDX-DLS: -14.7 SEA-EAT: -15.5 OLM-YKM: -14.5 East wind is making it's way all the way to SEA right now:

I'm up to 21, there are some thicker high clouds to my east, oddly enough. To the west it looks like there's some sort high haze/clouds? Idk. Hoping to stay below 23.

Got down to 17 before the easterlies hit around 3:30. Currently bumping around 18/19. Cold!

I’m down to 19 while SEA dances around in the low 20s. The wind needs to chill for a bit.

Had a few clouds move in and that bumped the temperature up to 21 from 20. Back down to 20.5. SEA is stuck at 21. The hope is it can drop to 19 before midnight.

Those 21s on the inter-hour readings are just rounded and are very likely readings of 22.

That would be amazing, but something tells me we score a low 20s high around 11:53 PM. Down to 21. You make it to 19 yet?

BLI-YWL is still -14.6. Down to 22!

I was on a work call with a colleague in Denver when it hit his area! It's down to 23 here. Dropping like a rock while it's still sunny. Love it. I can taste the teens.

Fraser Valley is a pass of sorts I meant in WA. Bellingham seems to escape freezing rain - I think Tim pointed out location on the water helps with the mixing.

So there's really no precedent in the last 30 years of major icing north of SEA (minus foothill near passes)?

Where was the icing in 1996? I know significant down in the Portland area, but up in the Sound? Was it limited to the S. Sound?

JayA seems pretty worried. Mentions cold air hanging on through Friday night and possibly longer - although it was unclear to me if that's in favored areas with proximity to low-level east winds or the Sound as a whole. I don't know of a significant Seattle/Central Sound icing event. 2012 was not bad at all in the city. It mainly stayed as snow - I didn't have more than like .15".

Looks like peak heating has occurred, closest station is down from a daytime high of 27 (midnight high of 29) and it's now 26. Happy Solstice! It's nice to make efficient use of the lack of sunlight.

A bit of a bummer SEA seems to have been at 30 on the inter-hour obs after midnight, so no sub-30 high today. 23/14 is going to be tough to beat. It seems like we can never really clear out nicely these days, but maybe the needle will be thread this time. That was a different mayor!

Lower levels are still pretty moist. DPs tracking close to temps. It’s only 30/27 at SEA. Would that help juice any convergence or more so arctic boundary?

Back to light snow here. Hard to see unless you look directly at the street light. Also some mist around. 29 F.

Will tomorrow have a midnight high for Seattle (and also PDX too), with temps continuing to fall throughout the day?

Snowing again in N. Seattle. Quite light. Not being picked up by the radar really. My god though. 17" in Vancouver!? 12" in Victoria, 8"-10" in Bellingham? That's quite the storm. It's like a colder, more widespread, longer-lasting 2/21 up there.

Flurries have returned although there is nothing on the radar. Temp keeps fluctuating between 29-29.5. Main road is looking bare and wet (treated) but everything else is a frozen mess.

You really did not miss out much on those previous events. Outflow temps + 8"+ snow > Slushy accumulations of <2".

Down to 29 here. Always fun to see the temp drop during max heating hours.

Snowing nicely again. I am just on the southern edge of that narrow band. I am seeing conflicting reports of its nature. Is it the final band of moisture associated with the departing low, some sort of post-departure convergence, or arctic front boundary?

That's what I thought too, but the temp dropped so fast and you still have fairly heavy precip that I think you should still see accumulation.
