another sunrise!

As I mentioned in yesterday’s comment, we in fact, did get a sunrise this morning! Many of you know to get two sunrises and two sunsets in a row is quite the treat!

One of the coolest things about working/living on a mountain is that oftentimes, you can see the weather coming at you. Sometimes it happens quickly – You see a cloud one minute and you’re in the fog the next. Other times, the weather will slowly approach from the west (or sometimes the southeast).

Something I almost always observe is the cloud progression of a warm front. Ever since my professor of Weather Systems mentioned it, I’ve been fascinated by it. With an approaching warm front, warmer air rides up and over cooler air that is at the surface. The result of this phenomenon, called over-running, is that the air moistens and warms from the top down. High clouds, starting as wispy cirrus clouds, will overspread the sky, becoming a thick layer of cirro-stratus. The next layer of clouds will start to spread out, consisting of thickening alto-stratus. Finally, the lower clouds will advance upon the region, usually bringing steady rain or snow.

Today we got to see the clouds increase overhead as a wall of virga approached. Early in the day, the snow on Whiteface was crystal clear. However, upon looking out the window around noon, the Green Mountains were shrouded by a veil of virga. Soon after, Moosilauke was no longer visible, and by observation time, not even the Franconia Range was visible. It has since begun to lightly snow. Seeing what I learned in a classroom in real life never gets old!
