Approaching change…

Three layers…haze sandwich!

Change is on the horizon this morning…literally. As I look out the western window of the office, I see the approaching cold front, in the form of a wall of clouds. The sight becomes more interesting though, as you examine the gradient from land to sky.

While the front approaches, high pressure continues its hold on the region. Underneath this high, stable air remains, and a haze trapping inversion continues between the valley and summit. And the haze is remarkably thick, with visibility reduced to 25 miles. However, the cut off line between the haze and crisp, clean air is also remarkably sharp, as you can see in the picture.

The front will put summits in the clouds in a matter of hours, and when we emerge, it is likely that temperatures will be roughly 30 degrees colder, possibly with a fresh coat of ice on the peak! We’ll keep you posted!
