We continue to dig ourselves out of a cold temperature hole with moderating values expected into the weekend and above freezing temperatures even by early next week. We've experienced a remarkable stretch of cold temperatures and the featured chart presents an analysis of the coldest ten day period each year for Des Moines for average high temperature. The season low value for this year is shown by the last bar on the upper right plot and there's only a handful of previous years with colder values shown. The left two panels provide the timing within the season when this period occurs and having such a period in February is only less frequent than January. Perhaps there is some solace knowing that the worst of winter, as far as temperatures, is very likely now behind us.
