Tonight, tomorrow, and the next night, Mercury is very close to Jupiter, and they both set about an hour after the Sun (somewhat depending on where you live). Tomorrow, they'll be less than the width of the moon apart.
PS: I was able to see Jupiter naked-eye just after 9pm, about 6 degrees above the horizon, and only a couple degrees above a thick bank of clouds. Mercury was below and to the right, but I never managed to pick it out naked eye, although it was easy enough in the binoculars.
I was above a swimming pool deck, with all sorts of deck lights on, so if you have clear skies, you should be able to see them, a bit to the north of west.
