83 in Chicago and 84 in Phoenix?

The weather lately is really strange for March. If it were June or July these temperatures might be closer to normal. But even then if it were 83 in Chicago we could expect 95 or even 100 in Phoenix and that is what makes these temperatures strange for this time of year. So, Chicago in March is 83 but Miami is only 82? and Phoenix is 84. The only two temperatures that make any sense for march would be Phoenix and Miama. And I'm not even sure about Miama's temperature this early in the year.

Note: For those of you not living in the U.S. , Chicago's weather should be about 50 to 60 degrees this time of year and maybe at the outside 70 degrees Fahrenheit so you can see the disconnect.
