The first ten days of November averaged 65 degrees for a high temperature for Des Moines. The following ten days are going to come up woefully short of that balmy value. The featured chart compares the 1-10 vs 12-21 November period each year for Des Moines for average daily high temperature. The chart presents a simple one-to-one line in blue and then divides the plot into quadrants based on the average values for reach axis. There isn't much predictive capability from one period to the next, so this year's situation isn't too far outside of historical norms.
