Daily Feature

Reaching 50+°F During December
Date: 23 Dec 05:30 AM
Votes: Good: 8   Bad: 0 Abstain: 0

Temperatures warmed very nicely on Monday with about the southwestern half of Iowa reaching 50+°F. The Ames airport reported a high temperature of 50°F, so today's featured chart looks into the frequency of having such a warm high temperature by day of December. The label on each daily bar is the number of years over the period of record for the site. For the last half of December, the average daily frequency is around 5% or about once every twenty years. We still have a number of warm days to go yet this week with the warmest temperatures forecast for Christmas Day. This may present a problem for those families that rely on the outdoors for expanded refrigerator space!
