I've always been a lover of overcast, dreary, wet and drizzling days. It doesn't get much better than being all bundled up in your coziest coat, strolling the streets and nuggling up with Bob on one arm and a hot cup of coffee/tea/cocoa in the other. Pure bliss.
Can't you just imagine us all parading through downtown all dressed up, carrying umbrellas? In my mind, rain creates such a romantic mood. And, I've heard it's lucky to have rain on your wedding day.
