Got schooled on wind limits by a weather guy in Kansas City

Three years ago I was on a job in Kansas City, setting steel for a new warehouse. The specs said we could run up to 20 mph, so I was ready to go at 19. An old meteorologist who lived nearby walked over and said, 'You see those flags? They're not lying.' He explained how gusts coming off the river could spike 10 mph higher than the reading on my meter. I sat for an extra hour until things settled. Has anyone else had a local give you a better read than the official forecast?

Local knowledge can be a lifesaver. I was surveying a site in a coastal valley once, and the forecast called for light winds. A fisherman told me to watch for the whitecaps on the distant bay, saying they meant a squall was funneling right toward us twenty minutes before it hit. He was spot on. Those little signs that aren't in the manual make all the difference.

That wind tunnel effect is real. I've seen it on a job where the breeze was fine in the open yard, but between two houses it would suddenly double and whip spray everywhere. You learn to watch for those tight spaces where the air gets squeezed.

Totally thought my gear was all I needed until a similar thing happened. Was pressure washing a big brick facade with a steady breeze, but this old maintenance guy pointed out how the wind was curling around the corner of the building and creating a nasty spray drift zone. He called it a wind tunnel effect (which I guess it was). I would have soaked the client's windows without his heads-up.
