An odd quirk of physics seems to be that a really dense cloud layer will apparently cancel out "inertia" and all those other nasties that wait to pull us into the ground during a "downwind turn".
For a demonstration of this phenomena, simply note the wind direction, climb thru the layer, once on top take up a heading into the wind previously noted and then commence a turn onto a reciprocal heading without any reference to the ground. Notice anything?
Or you could perhaps do a series of continuous 360's under the hood and try to establish which direction the wind is coming from.
