The warm up this weekend was replaced by very cold air on Sunday. After setting a record high temperature on Saturday for Sioux City at 62 degrees, it was -2 less than 24 hours later! The featured chart presents the largest downward temperature swings for the site as recorded by the hourly observations. The only event with a larger change was back in 1982 as the temperature went from 83 down to 18 between 2 and 3 April. Our weather pattern looks to be active this week with numerous chances of snow.
