One of the most eye opening events to me weather wise was finally realizing how high wind speeds can get even just 100 feet off the ground. When I was working at the Mashantucket Musuem we had Davis pros at 30 feet 75 feet and finally at 336 feet atop an observation tower. During a screaming soueaster we read simultaneously 35 mph at 30 feet 52 mph at 75 feet and 104 mph at 330 feet. Shortly after we measured the 104 Blue hill gusted to 101. I believe this was 2002??
