Daily Feature

Chance of Warmest October
Date: 13 Oct 05:30 AM
Votes: Good: 12   Bad: 0 Abstain: 0

Our warm October continued this past weekend with highs reaching 80+°F over much of western Iowa on Sunday. A daily feature last week denoted the first five days of October were the warmest on record for many sites in Iowa. Today's featured chart looks into if this October could be the warmest October on record for Ames. The month to date accumulated average temperature is plotted along with each previous year providing a possible scenario for this year to potentially bet the warmest October during 1963. Interestingly, only that 1963 scenario repeating would lead to this year being the warmest on record. The actual forecast for this week continues the mild temperatures without much in the way of significant cold.
