I have to have 50mph plus to do that, with a certain wind direction, almost has to blow down the road pulling the knocker away from the door as the pressure drops in the doorway, so a south westerly! Maybe it will happen tonight, although I hope not, it sends the dogs balmy
edit:
Actually the squall hasn't gone the way of the dodo like I assumed, the radar has clipped some detail off.
I await the next update! It has definitely died down, but I'm not sure how much, oh and it will now miss me, skirted to the north
