Should I open colonies to feed on a warm,rainy day?

[GaryMinckler]

Today it's hitting 50 degrees, but wet.  I have two medium supers of capped honey from colonies that were lost.  I'd like to put one on each of two other colonies to feed.  Should I do it?  When I opened my garage door everything was covered with condensation within seconds. We're in a kind of "January Thaw" type of weather system with lake effect snow predicted by Wednesday.  I'm thinking a sunny,drier but cooler day might be better

do they need it?

The biggest reason I think they need feeding is when I peeked under the telescoping cover there were a lot of bees around the hole in the inner cover.

I did ours in Maine yesterday because I knew this weather was coming and it's suppose to get colder. It was in the high 30's but sunny yesterday so I just did it as quickly as possible. With the extra honey they now have I feel they have a better chance of making it. At 50 degrees I'd have someone hold an umbrella while you add those supers as quickly as you can. That 30 seconds or less that your hive is open won't hurt them but the honey you give them will definitely help them. I'd do it.
