Just eight days ago, some Iowans enjoyed record high temperatures in the low 60s. Today, it’s a much different story. Meteorologist Jim Lee, at the National Weather Service office in Johnston, says an arctic air mass is bringing bitter cold into the Hawkeye State and portions of northern Iowa are under a Wind Chill Advisory. “We have fairly modest-to-brisk northwest breezes and very cold temperatures combining for wind chills of 20 to 30-below across northern Iowa,” Lee says. More snow is on the way, too. Lee says several Winter Storm Warnings, Watches and Advisories will be going into effect soon for much of Iowa’s northern half. “We’re expecting to see snow spreading in from northwestern Iowa after midnight tonight, continuing through Friday,” Lee says. “Accumulations across parts of northern Iowa will be close to five to seven inches, down around the Missouri border, virtually none, so there’ll be a pretty sharp gradient somewhere across central Iowa.” More super-cold air will be arriving in Iowa this weekend with another chance of snow by Sunday.
