I second what Brad said. Unless you are just wanting to see if you can do it, why would you want to? Extreme cold weather is not easily taken care of with the best clothing and equipment. Like Brad said, you MUST be aware of your own personal limits and realize that if you did not get down in time or were not prepared to have a back-up plan should something go wrong, then it is just not wise. There is a book called -148 which details a winter ascent of Denali. The group had specially made gear. The title is what the thermometer read in Fahrenheit on one occasion. If the wind is making the temp. dip that low, you probably wouldn't want to be on the summit for that reason alone. Even in the Summer, strong winds are not a good idea unless you are made of mercury. Be safe.
