What's up with the weather here?!?

We have had some crazy weather this weekend...
Saturday was a beautiful sunny day. I went to Provo with friends and tubed the river there and enjoyed bathing in the sun all day. The weather was perfect for swimsuits.
Sunday morning and early afternoon were great. A slight breeze was always present and the temperature was just how I like it... cool enough to not die, but warm enough for cute dresses. Then the evening came... and it stormed. It stormed for hours!
This morning (Monday) when I got up it was a little drizzly outside and I was freezing! The high for today was in the high 50s I believe.
So in a matter of three days I went from basking in a swimsuit to breaking out the sweaters and boots and still wanting a jacket when outside. What am I going to do when it gets really cold?!? I guess being a Popsicle is what happens when a girl raised in SC moves to the lovely winters of UT! The up side to the weather: it'll be in the 80s again by the weekend.
