We are on our way back into the cold by the middle of the week so read on for the details…
A strong arctic cold front will slide through the state later Tuesday night combined with strong northwesterly winds helping to blow the cold Canadian air down into the state by Wednesday. The strong winds on my wind gust intensity scale will be around level 1-3 so plan on advisory type gusts across much of the state. The strong gusty winds will be around for much of Wednesday before subsiding later into the evening. This will bring low temperatures down into the single digits Tuesday night with a few areas possibly below zero across northern Iowa. A even stronger wave will hit later Wednesday brining low temperatures below zero state-wide Wednesday night. Wind chill values of 10-25 below will exist across the northern half of the state Wednesday morning with the extreme cold wind chills of 15-30 below following Wednesday night into Thursday morning state-wide.
