IOWA — Central Iowa is again starting the day with sub-zero temperatures and sub-zero wind chills thanks to an arctic ridge of high pressure. However, it is not as cold as we were on Tuesday morning, a layer of clouds is helping to keep us from bottoming out this morning. Those clouds will clear tonight with colder air by Thursday morning.

A Cold Weather Advisory is in place across Central Iowa this morning through noon for wind chills of -15 to -30 below.

A new Cold Weather Advisory will go into effect at 9 PM tonight for Central Iowa and an Extreme Cold Warning for western Iowa from 9 PM through 9 AM on Thursday. Wind chills in western Iowa may drop below -30 tomorrow morning.

Here’s a look at expected wind chills Wednesday through Thursday noon:

Despite the cold, temperatures are on the upward trend. We’ll see above-average temperatures by next week.
