10:42 A.M.
Folks, let me just start out by saying that the Seahawks game yesterday was incredible. Especially since I would have lost all my hair had the Hawks come up short to the Patriots via a bet with a New Englander. Now, normally, I wouldn’t care about losing my hair (free haircut, right?), but after looking at the models, I’m pretty glad the Hawks won. It is about to get COLD here in October, and I don’t know if my body has quite adapted to the change yet, so I need all the extra hair on my head that I can get. Nevertheless, I am still extremely excited, because if the long-range models turn out to be correct, we will get an early start to our skiing season, and it’s been far too long since I’ve been on the slopes.
For now, though, we’ve got some weather to go through.
This picture above was taken from the Seattle National Weather Service’s graphical forecast discussion, and it shows the storm we will be dealing with today currently off our coast. This storm will move quickly through the area and give us a brief shot of heavy rain and a good deal of wind to boot. In fact, we currently have a low-end wind advisory over our area for 5 P.M. tonight to 5 A.M. Tuesday morning. Below is the exact wording of the advisory.

As you can see, we are on the very low end of the wind advisory, with gusts to 45 mph and sustained winds of 20 to 30. I have a feeling that if this storm occurred in December, a wind advisory would not be issued. The reason why it is being issued here is because many of the trees still have their leaves on them, and they also have a bunch of dead branches that haven’t been blown off by previous storms because, well, there haven’t been any. A closer look at the UW’s high resolution 4km WRF-GFS shows us that the winds won’t be anything to really worry about. Of course, relative to this past summer, it will probably feel like a hurricane out there.
