Time for Warmth Yet
Posted: 23 Oct 2026 05:30 AM, Views: 687A week of wonderful fall weather looks to last into the weekend prior to cooler temperatures along with rain chances to start off next week. There have been plenty of daily high temperatures into the upper 70s this week and one may wonder how much longer into the fall season can such temperatures last? The featured chart attempts to answer that question by plotting the latest calendar date a given high temperature was observed at or above a given threshold. The first item to notice is how anomalous the 15 December 2021 event was with a high temperature of 74°F that day! Values in the mid to upper 70s are possible for a few weeks yet, so there is still time for such warmth to occur!
