Where's the rain?

Today it's the most beautiful day here in Montreal. It's sunny and warm! Somehow though, there's one dark cloud that seems to remain. It's been here for awhile now, and won't go away. Will it rain already so that beautiful, clean and crisp air can arrive? Or maybe it IS raining and the true sun at the end of that tunnel is closer than I think. There are moments when a beautiful rainbow appears, but they don't last very long. Is that what I'm supposed to cling to? Have I lost all perception?
