Next Day Change

Posted: 15 Jan 2016 05:11 AM

The past three days have seen warmer high temperatures each day for much of the state. How frequently does the daily high temperature increase, decrease, or stay the same from the previous day's value? The featured chart displays such a metric for Des Moines along with the actual frequencies for 2015 for comparison. While there is an annual signal in frequencies, its amplitude is not very large. Restating, the climatological pull on day to day temperature changes is not very strong with much of the variability explained by actual weather. For this weekend, the weather brings much colder temperatures with similar temperatures to what was experienced last weekend.
