If you watch weather reports closely, there have been circular fronts passing thru so wind is changing every few hours from the circular movement. Day to day and every 8 hours or so cause the wind to change. Once these fronts are straight line, winds will be more uniform and easier to predict. Fall causes all kinds of wind issues with the temp changes !!! For what it might be worth, I use the NOAA wind and wave forcast for western lake erie, it has been reasonably reliable....
