Sioux City was only able to reach nine degrees for a high temperature on Wednesday. While one would hope we are close enough to spring to prevent such cold temperatures, we are still in February and such cold is still well within climatology for this time of year. The featured chart presents monthly percentiles and return intervals for having a daily high below ten degrees for Sioux City. For February, the return interval is about five days every three years. The frequency does decrease significantly going into March, so hopefully we can soon get past this very cold weather and start some semblance of sustained spring weather!
