(Radio Iowa/KJAN data) – State Climatologist Justin Glisan says snow was the main feature of the weather in December. “You look across the swath from southeastern Iowa up to northwestern Iowa, above average by anywhere from four to eight inches. And then you get into the northeast corner and the southwest corner, it’s below average in terms of snowfall,” Glisan says. Glisan says the snow impacted temperatures in December.
“Temperatures were about one-point-seven degrees below average. And again, that was anchored by colder temperatures and more snowpack in eastern Iowa,” he says. “Precipitation about an inch, that’s about four-tenths of an inch below average.” Glisan says December was pretty ordinary on most accounts.
“On the snowfall, even when we had that above average swath across the state, we came in right about average. The normal was seven-point-nine inches, preliminarily, we’re about eight inches,” Glisan says. He says there’s nothing in the December weather that’s noteworthy as far as records go.
