KANSAS CITY, Mo. — Icy weather conditions are impacting flights for people traveling through Kansas City.

Just before 7 a.m. the Kansas City International Airport (KCI) closed its airfield due to ice contamination on the runways. Airport crews worked overnight to de-ice the runways, but ultimately the airfield had to be closed as a safety measure.  

At least one runway opened before 8 a.m., leading to resumed operations.

Travelers are still encouraged to check their airline for the latest updates on flight delays and cancellations. 

The entire Kansas City metro is under a Winter Weather Advisory until 3p.m. Thursday. The FOX4 Weather Team is tracking a wintry mix expected to switch over to snow by mid-morning. You can find the latest updates on road conditions and closures online at fox4kc.com.
