Starry, starry night...

Personally, I didn't think you would see Mercury unless you have a powerful telescopic and you see it as it passes in front of the sun.

I was awake just before dawn and couldn't see anything to the south although it might have been cloud - there was clear sky higher up and a very bright something fairly high in the west?

Scan the sky southeast to southwest. Venus will be the most visible. Our weather forecast is pretty awful tomorrow so we wont be seeing anything until things improve.
