I suffer the same problem... I use wunderground.com, weather.com and the weatherbug to get a better idea of what might be out there.
I had good luck on Sunday (17th). Had a bit more than 15 mph of wind when I started. The wind lasted during all afternoon. I shared the lake with three (3) motor boaters who rarely crossed my way. At 7 pm I was encouraged by the park ranger to hit home. Had a good time.
