If you're worried about your bees and the weather, you could always put a tarp roof over the top of your bee hive. Of course you'll have to build a frame over it, and make it tall enough for you to walk under it. But that's a way to protect your hive from the rain. You can also stack straw around the sides in the winter, obviously not where the opening is, but the straw will keep the heat in . Just a suggestion, of course, take it or leave it.
