Does it really have an effect on anything or is it just cosmetic. It really doesnt seem so on field goals or passing game. If it does have an impact on kicking then having a basic setting for max FG would be way off if you had a 15+ mile an hour wind in your face

I've wondered that myself.

On a side-note...
There was a satanic edge to New Yorks visit to Detroit, Attendance: 66,666

There is an effect, but because you can't gameplan around it it's not terribly significant. For example, fumbles are more likely in precipitation, snow reduces traction and acceleration. Wind does affect the flight path of the ball and thus will affect FG accuracy depending on which direction it is blowing.

I do have a plan to include the forecast, and once that's in place increase the influence.

Wow, I saw an Arizona game with 101 heat and thought how they'd fair if they had to travel to say Green Bay.
