Mr_G, again sounds spot on, we were north side, and it passed left to right on the south side of the river, can't recall it being any lower than the usual LHR aproaches. Still theres probably some dusty cupboard in Bracknell full of scribbled tomes of Metars!. As a particularly useless piece of info, I did my Met Observers practical at LHR, and it snowed!
