While temperatures were below freezing for all of Iowa on Wednesday, the warmest locations were found in southeastern Iowa. For the sake of comparison, how often is the daily high temperature for southeastern Iowa warmer than northwestern Iowa? Using the climate district averaged values for this question, the featured chart presents the daily frequencies of having the high temperature one degree warmer for southeast vs northwest. The overall average is shown and frequency for February is about 80% or four out of every five days! While this frequency does drop during the summer months, the value is never shown to be less than 50%.
