A Winter Weather Advisory is in effect until 3AM Thursday for the metro and areas along and north of I-80. This is where blowing snow will make travel difficult at times.
A Wind Chill Advisory will be in effect from 3 AM to 11 AM Thursday for Central and Northern Iowa. This is when wind chills will drop to -20 to -30, so plan on another very cold start to the day.
Thursday will be sunny and VERY cold. Temperatures will just barely get above zero with a high of only 4 degrees. Wind chills will hold below zero all day.
Another storm system will bring light snow to Central Iowa on Friday. Temperatures will moderate to the teens during the weekend with more snow possible Saturday night through Sunday morning.
