Much of Eastern Iowa was blessed with temperatures that reached 70+ on Tuesday, February 27th. One day later, most of eastern Iowa didn't even get above freezing. We went from shorts and being comfortable outside to busting out the winter jacket and gloves in a very short amount of time. We had shut the heat off at my house for 3 days before we had to turn it back on for 1 day.

According to Time And Date, the high in Cedar Rapids on Tuesday was 75 degrees and on Wednesday, the high was only 28 degrees. If my Iowa math is correct, that's a 47-degree difference. This February has been warmer in Iowa and most of the Midwest than we normally can expect. If you don't remember, a warmer winter was predicted back in November, as El Nino is believed to be a major factor in the warmer temperatures.

With the drastic change of 47 degrees from Tuesday's high to Wednesday's high, have you ever wondered what Iowa's biggest temperature swings are?
