The featured chart presents the year to date minimum low temperature for Ames. The chart shows this year's value along with the climatology of such an accumulated value. The very cold temperature below zero during mid November dropped the value well below climatology, but we have yet to breach that level since and so attrition has us back near the the inter-quartile range for the second week of December. Colder air will drop temperatures during Monday, but nothing sub zero is expected. The chart nicely shows that climatology for this metric creeps downward until about mid February, so we will likely see colder temperatures yet sometime this winter season.
