Pretty crazy morning. No power when I left home earlier this AM, and quite a few branches down in many spots.

12Z GFS is showing some Christmas flurries but is trending drier as it shows the trough getting cut off and diving offshore into California. This run is showing a modified arctic airmass though.

Extended range looks fun on the Euro. Dynamic storms. Instability. A mother of all AR's that impacts the central coast and slowly slides down bringing cold air behind it.

I’m a little more optimistic. Slushy rain for most, wet snow for Pornoman.
