Coldest temperatures in 18 years

Sometimes you don't want the weather forecast to be wrong.  In this case, the forecast was that the high would be -2 today.  It is so cold today.  When we got up this morning, the window above the front door cracked diagonally.  It made quite a noise and was very scary (mostly because all I could think about was how cold it would be if the whole thing fell in)

All our windows are covered in condensation because of the temperature difference.  It's not going to get any better for quite a while....
