In the image below, Venus is the brightest planet at the bottom, Mercury is the dimmest up and to the right. Jupiter is to the left. Zooming in on the original image, I was able make out the moon Europa below and slightly to the right of Jupiter and the moon Callisto up and to the left.

Update 2013.05.31 - Five nights later, we had another break in the clouds though the low haze was still problematic. The planets had now rearranged themselves to form a straight line. In the picture below, Jupiter is in roughly the same part of the sky but is now at the bottom of the grouping. Venus and Mercury have both climbed rapidly into the sky. Venus, always the brightest is in the center and Mercury at the top. In the upper left corner of the image you can also make out the magnitude 3.5 star Propus in Gemini.
