I've lived in Kansas all my life and it gets pretty darn cold. Nov. Dec. Jan. and most of Feb. are usually in the teens to twenties. Some days we are in the single digits and if we're lucky, we have a day above freezing. Some years we have just 1 or 2 snow storms and an ice storm or two. It really depends on which side of the state he lives on. I'm in the eastern part, but if he lives in western Kansas, he'll need A LOT of hats and scarves. They get a lot more snow out there.
