Cold Bias

Posted: 01 Feb 2013 05:44 AM

Most of the state is below zero this Friday morning. The featured chart presents an analysis of the ratio of days above 100 degrees to days below 0 degrees Fahrenheit. Locations with more days below zero have the ratio flipped to keep all values positive. Locations in white are the closest to having equal days above 100 and below 0. Nearly all of the Midwestern US has many more days below zero and there is a large gradient over Iowa. Southwestern Iowa has roughly 10 times as many days below zero than above 100, while Northeastern Iowa is around 100 times as many days! The moral of the story is that the number of days below zero dwarfs the number of days above 100 for most of the region.
