Got Those Thermoregulation Blues!

Yahoo weather is telling me that the temperature in my tiny town is going to rise up into the hundreds this weekend.  This is powerful news to a little family that lives without air conditioning or even a fan.  This morning it was impossible to believe since it was so chilly when we woke that I put on a sweatshirt and sweatpants.  Now it's past noon, though, and the sun has moved out of the woods and into the middle of the sky.  I'm feeling the first serious warmth sink into my bones.  Am I worried?
