There is a theory that because the coming of moshiach has to be at a certain time, Hashem wants to make that time sooner. So he pushes in into one year a few winters and summers one after the other so one year becomes like a few years so moshiach can come faster.
If this has any truth (can anyone verify this?) then the past months is for sure a ripe example of it! (hot, cold, hot, cold)
