This one's for my friend Stan, who asked if we had this particular weather phenomenon today. And of course he guessed correctly. With the dramatic warming trend of the past two days (as in, the temperature is sixty degrees higher today than it was last Saturday) we had a near perfect Chinook Arch, which is the arc of blue sky over the mountains that often heralds a warm front.
Unfortunately, it almost always comes with a Chinook Wind, but we'll take it anyway.
