Spring Wave

A friend (Mark Lindberg) was skiing at Attitash last Thursday (3/17) and took these pictures looking toward Mt. Washington (to the left).

Here is the skew-t:

I guess the clouds were around 12,000'. Surprisingly light wind (multiply w/s in m/s times 2 to get kts). About 26 kts at 6,000', 40 kts at 12,000', 46 kts at 18,000'. The observatory on the summit of Mt. Washington was reporting 40 kts.
