Sure doesn't  seem like it yet.

Nice and sunny here with night/morning lows 35*.

 

Enjoy the change of season.

It was sunny crisp day here. Felt more like mid fall than the beginning of winter.

Yesterday around Lake Tahoe on the trails cut some trees out  that blew down and it was nice upper 40 degrees.  There is not much snow on the trails..  Today another Blue Bird day did some birding in Reno and was in the 50's.  High pressure needs to break down so we can get some storms moving in.  Looks like back East winter arrived.

We are under a persistent high pressure ridge that caps the deep valleys with an inversion layer.

So as we suffer through these agonizing days of clear weather, we woke up this morning to 45 degrees as an overnight low (the high will be 56). Our neighbors below woke to the 20's and 30's.

That's us when the inversion layer happens here, up at the lake is warmer than us.  Sometimes after a snow falls we don't get solar warming and then a inversion hits and we are under fog for days.  Only relief is to head up the hill to Tahoe to see the sun and feel the warmth.

I didn't realize you got those on the west slope of the Sierra, but I guess there are some topographic similarities between the Valley being sandwiched between the Sierra and the Coast Range and the Salt Lake Basin being sandwiched between the Wasatch Range and the Basin and Range highs.  I've never seen anything like the inversions in the Salt Lake basin in midwinter.  As you note, you can descend from Park City/Parley's Summit (Pass) at +7,000' in the bright sunshine at 40-45 degrees F, and as you penetrate the tan to brown cloud headed west from Parley's, you're in so deep the sun is all but totally blocked out, the air is acrid, and it's 20-25 deg F colder.  That can persist for a week to two weeks at most any time in winter.

Down in the Central Valley the annual migration of birds has begun.   I went down to catch the full moon and saw tundra swan, white faced ibis, cattle egret and great egret, white fronted geese, and numerous raptors including a white-tailed kite, kestrel, red tail hawk.

 

I'm trying to squeeze in a trip down to Cosumnes Nature Preserve to photograph the sandhill cranes which has arrived.

I know this will come as a surprise, but here in Portland OR we have had clouds, rain, no snow, and some rain, in between rain showers. Although today was sunny! Forecast is for... let me check.. oh, yeah, clouds and rain.

Very windy, cold Santa Anas, we live at the end of a natural wind tunnel. We’re on fire watch. Also, very big surf off our county coast. Big surf + offshore winds = crowded wavelines but happy surfers.

I saw "freezing fog" in the forecast for Bend, OR, one variation of temperature inversion...and my least favorite weather. Weather that's cold - and feels colder because of the dampness... But not sunny and cold... And not cold and snowing. Just pointlessly unpleasant.

One time, about 35 years ago, we had a bad, cold inversion in Bend right around Christmas. Christmas Eve the HIGH in Bend was 5°F BELOW zero. And yet, 25 miles away up at Mt Bachelor, at 6000 feet, they were skiing in sunshine at 32°F!

I'm 2000 miles from Bend right now...and not complaining.
