A Huge Inversion

Monday, December 5, 2011
10:20 A.M.

Hi everybody. Sorry for not writing the past few days, my computer has been at the shop and I haven't had access to one. I am writing this post at the library and I need to be sitting down in a class in nine minutes, so this will be a very short post.

Right now, we are under a gigantic inversion. Take a look at the temperatures taken from the Sand Point profiler at 9 A.M. this morning. In many spots, the air temperature actually increases with height, showing that an inversion is above us. This means that we get air pollution, fog, and relatively cold temperatures compared to places with higher elevation. Want to escape the cold and smog? Head up to Tiger Mountain.

Remember that arctic blast threat I was talking about? The models are now in consensus that we will not see a full-on blast. We will be chilly, but we will not be frigid. It was exciting to see, but it was super far out, and model accuracy declines rapidly with time, especially after 120 hours. The models are in agreement that this cold air will head further east.

This pattern of rather mundane weather looks to continue into next week.

Got to go!
