Why is it?

I'm leaving Denver in 2 days. One of those days, I am packing up the truck etc... Now, I have no problem with that. My problem is, out of the past month or so, it has been absolutely GORGEOUS weather, and it decides to start snowing TODAY?!?!?! Not only today, but tomorrow and saturday are also supposed to get snow. Those are the only 3 days that Meghann is going to be here, and it's going to be colder than it has been recently, all while snowing. Sunday, on the other hand, is supposed to be f-ing 60. WTF?
