First snow of the year! Melting quick but at least a little left. Was down south picking up a new family member. 

Beautiful morning in the Blue Mountains of eastern Oregon. It was 12F when I took these pics around 8:30am. Gotta get our winter fix somehow.

Major shift on the 12z EPS to lower heights over the West with rising heights in the SE compared to the 00z last night. Looking like a really fun mid month on through the Holidays. Perfect timing IMO!

That's a pretty significant drop at the end.

That's because the final day only goes to 12z aka 4am PST.

Oh something is definitely brewing!

The pattern change is showing up a bit more clearly out here a bit further to the east. Patience.

That looks really good. Maybe we will see some winter action here before the month is over in the second half. Just based on the fact it’s La Niña I figured we would be waiting until atleast January for something interesting but we will see.

May this winter be filled with endless ridging (if it isn't going to be bone-chillingly dry and cold).

For being someone whose name means 'snowy' that's very big of you to say.

By dry, I mean low dews that come with continental air. Of course, I would absolutely love several huge dumps of snow. :D

Looks like we barely hit 40F but I doubt we get much higher.

Wind advisory and air stagnation advisory at the same time? Okay, NWS.

That's hilarious! I wonder how rare this simultaneous combination of warnings is? Maybe not so much around Portland due to the complicated relationship between its frequent east winds and highly variable topography...?

Sounds like some places in the forecast area might get some East wind while others might see fog.
