We have officially begun the Inversion season here in Boise. That means solid gray overcast and temps colder here in the valley than up on the mountain tops.  The swing between day high and low temps is around 4-5 degrees. As an example for the last few days and the next few forecasted days highs will be in the low 30’s and lows will be in the mid 20’s. Brrrrrrr! Good news is that so far the third element in the equation, air quality, is still good.  After a couple days of these conditions I get in a funk. So with 1 out of 3 parameters in the green I triple-layered up and went for a ride today in a balmy 26 degress. Feel much better now.
