I don't know about all those terms but I know a storm can be coming from the North but the wind will be blowing from the South. I have seen clouds going in one direction up high and wind blowing from the opposite directing at ground level. I think this is the approach of the front, once the front passes the wind will change direction. I don't know if that helps but it is just what I have noticed.
