Sunshine After the Rain

Rain on a sunny day. Weather of this sort is like an oxymoron.

From which perspective should I view this?
Does it mean that I can expect to see a pretty rainbow after the rain? Is this sudden downpour a reprieve to the summer heat?
Or does it mean that life sucks? Even on sunshine-y days, you never know when it will pour and soak you to the skin?

Whatever it is, it’s good to see sunshine after the rain.
