When will there be another warm day?

The last warm day was New Years Eve, it's been too cold to open the hive since and it's just been predicted to be the coldest week of the winter season next week; -14C on Wednesday.  I hope that on Wednesday at the first beekeeper meeting of the year there will be some good advice on what and how to feed the bees, if they need it, when it does get a bit warmer.  I hope we do get a break as I think this is being hard on the girls.  Time will tell I suppose, and there is little I can do about that!
