Yes. The upper plains are no joke, though it isn't as if Kansas can't be 105 and -20 in the same year either. I remember a year in Lincoln going from -26 to 100+ in about 5 mos. Its really those days that drop 40+ degrees within minutes that the Plains can experience which is just a marvel. I believe Montana has the biggest 24 hr swing on record thanks to Chinook winds, going from -52 to 49.
