The two main headlines as we end out the work week will be the cold, and the snow. Highs over the next couple of days will be similar to those today. By Wednesday night, wind chills will be dropping into advisory criteria across northeast Iowa. Wind chills across northeast Iowa will be 20 to 25 degrees below zero.
Some light snow will begin to enter into the northwest portion state by Thursday night. Light snowfall accumulations will be possible north of highway 20 by Friday morning. The main system will then arrive during the day Friday, which appears that it will come in two waves.
The first wave will provide the chance for all snow across northern Iowa, with a chance of freezing rain south of I-80. Any ice accumulations would be very light, but still enough, to possibly make for a few slick surfaces.
By Friday evening, all precipitation will transition over to snow. There should be a break in the snow by Saturday morning, before more snow begins from wave two by Saturday afternoon.
Accumulations appear to moderate to heavy across northern Iowa, with moderate totals along I-80. Since this is still a few days out, we will wait to share any snowfall forecast maps just yet. As things continue to become more clear, continue to check back to IowaChase.com for the latest updates.
