You mention bike cover, if you are hooking under the footpegs, yes, you have a big sail. Do you have a topcase? Just me on the bike with 30KM/HR cross winds, I can feel it on the bike ( I have a Givi E56 topcase), the second thing is you mention the steering lock, yes a bad idea, the lock should have been right, that is Kawasaki. You can try from the shifter side, which is easier to tip the bike right, having the steering hard left as in steering locked position or hard right. Also think about push steering, push right for right, left for left.
So do I think the wind blew it over, 98% sure, especially if you have a tall windscreen and a top case.
