November Slide
Posted: 02 Nov 2026 05:30 AM, Views: 511After only one day with wide spread sub-freezing temperatures during October, November has started off mild as well with the forecast for the first week of month remaining well above freezing for low temperatures. It continues to be remarkable to denote how much warmer low temperatures have been compared with climatology. The featured chart presents a comparison between various daily climatology sources for Ames for November. The tan bars represent simple period of record averages and the three lines show the last three renditions of the official climatology. The "pull" of climatology is obvious with days getting progressively cooler and this "pull" will get harder to fight against if our current mild weather pattern is to continue.
