50% Chance of Rain

Why do some good raincoats, the ones you wear over suits, have heavy linings?  Besides the fact that you're already wearing a jacket underneath, if it's that cold, it's not raining.  And when you think about it, why do you really need a good raincoat anyway?  Men really don't wear hats anymore other than a baseball cap, which you shouldn't be wearing with a suit unless you invented the internet, or something really goofy that they think is cool but not only isn't cool,  it isn't waterproof.  So if you're not wearing one of those hats they wore in the days of black and white movies, you're going to have to have an umbrella to keep dry, in which case you won't need a raincoat, will you?

I suppose you can get by with a slicker over a sports/suit coat if it's raining, but it's not top choice.  But if it's cold, it's the pompous top coat or shivering with nothing, unless you've got an enormous parka (or worse yet a not enormous parka), in which case you've got other problems.

And about having problems, what about those human oddities that wear too-big raincoats on clear days?  There may be lots of reasons for that, and they're all bad.

And finally, meteorologists, and pretty much everyone else, should not be allowed to make the infamous "50% chance" call.  Just admit that you have no idea.
