Well, the actual temperature on that day was only -4F, but that was the wind chill factor, to skin, it felt like -30F, and it was a record here I think, it was the coldest that day than it has been in over 50 years.  It has been a very bitter, and very dry winter here.  Way below average temps all winter so far, and way below normal precipitation.  Like...maybe 6 inches all of 2010.  That's not much more than the most arid desert gets.
