The National Weather Service office in Des Moines has extended a winter weather advisory until midnight Thursday and issued a wind chill advisory in effect from midnight Thursday until noon Friday.
Little additional snow is anticipated, but persistent strong winds, producing blowing and drifting snow and blizzard conditions at times, will continue. Visibility will be significantly
reduced, at times to one-quarter mile or less in rural and open areas.
Lingering light snow and slick roads will remain over central and parts of southern Iowa as well, producing hazardous driving conditions.
The strong winds, gusting to 40 mph, and blowing snow should diminish overnight but will still be sufficient to drive wind chills into the 20s and 30s below zero across central Iowa by early Friday morning.
The cold wind chills could cause frostbite on exposed skin in as little as 30 minutes. Use caution when traveling, especially in open areas. Make sure you wear a hat and gloves.
