Some eastern Iowans may have experienced the phenomenon of “thundersnow” early this morning, where you have claps of thunder booming and snow flying at the same time. While it’s four days into spring, it looks an awful lot like winter, according to meteorologist Rich Kinney at the National Weather Service office in Davenport.
He says parts of eastern Iowa are seeing colder-than-normal temperatures — and snowfall. “Especially up around the Highway 20 corridor, areas from Dubuque over to Freeport (Illinois) with amounts of three to four inches,” Kinney says. “To the south, down to around the Interstate 80 corridor, pretty significant wintery mix with snow, sleet, freezing rain and creating slick road conditions.” Seven counties in eastern Iowa are under a Winter Weather Advisory.
Kinney says it’s not that out-of-the-ordinary to have winter weather during early spring. “You can get a lot of volatile weather this time of year,” Kinney says. “In fact, we get through this system and we’re looking ahead at rain and thunderstorm chances overnight tonight and into Tuesday.
Weather can really turn on a dime this time of year.” The forecast calls for another chance of snow in eastern Iowa Thursday into Friday. Just a week ago, many parts of Iowa had highs in the 80s and Sioux City hit a record high of 90 degrees.
