This week’s On The Radio segment looks at unusually high temperatures and precipitation levels that Iowa experienced at the end of 2015.

Transcript: Warm fall and winter

While global temperatures continued to set records, Iowa experienced an unusually warm and exceedingly wet winter in 2015.

This is the Iowa Environmental Focus.

The United States Department of Agriculture reports that between August 31 and December 31, only 25 days recorded below average temperatures in Iowa. Temps during that period were 5.8 degrees Fahrenheit above normal, the warmest for that period since 1931.

Iowa also experienced by far its wettest December ever in both rain and snow, with a single storm system in mid-December shattering the records set by most winter months since record keeping started in 1873. Grundy Center’s 8.2 inches of precipitation dwarfed its previous December record of 3.7 inches set in 1982, while Des Moines’ 5.4 inches broke its previous record of 3.7 inches set in 1931. This continued a trend of unpredictability in weather patterns – which even included the first ever recorded tornado warnings in December. The heavy precipitation contributed to devastating flooding downstream from Missouri to Texas.
