Wind is often “vertically stacked” meaning that the winds can blow, not blow, blow in different directions, but separated vertically. So it is quite possible and very common for there be less than 2 mph breeze at ground level but blowing 20 mph up at 100 feet.

I noticed this effect while working on skyscrapers inspecting welds and bolt connections. There would be little wind at ground level yet 20 MPH winds 30 stories up.
