Just a little breezy here... but barely noticeable.Β  Β Hopefully that means the focus of the wind will be to the south later today.

Crap i forgot to report.

My cabin weather station reported a low of -29.6 on December 22nd.Β 

The lady who owns the Chesaw mercantile had a low of -38.Β 

Colder than I have ever experienced. In the valley where I went to college, the valley floor could get -40’s and even the odd -50 but campus was on a bench up on the side of the valley and never even got all the way to -20. But they got strong drainage winds from the mouth of a nearby canyon, and let me tell you -15 with gale force winds is brisk.

It's called clown range for a reason.

EURO actually increased easterly winds a fairly significant amount in the short term-- I think the wind advisory was a good call.

Currently mixing a lot better than most models thought. Up to 50F at KSEA. GFS had us still clinging onto the upper 30s through the afternoon.

North of Green Lake, winds are calm and temperatures are holding in the mid 40s. South of Green Lake, there's a fairly persistent easterly breeze with temperatures in the low 50s. Downtown Seattle is among the warmest spots in the PNW with some 53F readings in there. Have to go to SW OR to find warmer temps... Some mid-upper 60s down there!

It's really surprising to have so much east wind when it's raining. Why is that? Raining hard here. Will be 50 here tomorrow, otherwise in the 40s.

Low pressure system offshore driving in the precipitation, and contrasting with higher pressure inland, forming an E-W pressure gradient across the lowlands, and easterlies near the surface. Not our most common type of system but it does happen from time to time, and this winter in particular has had a notable amount of these types of systems.

Precip is staying as rain simply because there isn't an Arctic airmass east of the Cascades. Pretty benign air in the 30s at ~3k ft just over the terrain of eastern WA/OR is adiabatically warmed to around 50-55F ish as it is forced west and descended down the foothills.

On top of that, the rain falling over your area is causing evaporative cooling, keeping the air in the low 40s even as it descends, instead of a dry adiabatic warming into the 50s. Lowkey kind of a complicated setup.

Only 40/41 here. There was some decently strong east wind here in the morning, should be fun once it really ramps up.

Coldest I have ever experienced was -16F with a windchill of -40F. Quesnel BC in February 2019. It was tolerable in small increments but probably not as bad as I was expecting.Β

Will be interesting to see how far the temps crash west of the cascades if any heavy precip makes it into the sound.

Should be some pretty good evaporative cooling.
