The evening model runs are coming in, and they continue to show consistency with what we showed you earlier this afternoon. A clipper system will be moving out of Canada tomorrow evening and that will bring the potential for accumulating snow across much of the state. The moderate snowfall totals look to be across central and western Iowa. This is where 2″ to 3″ of snowfall accumulations looks to be possible with isolated 4″ totals.
Taking a closer look off of the 00z WRF, you can see where this band of snow will be setting up. Snowfall will begin across western Iowa after 8pm Tuesday and will then enter into central Iowa around midnight. Snow will then continue through Wednesday morning before clearing out of western and central Iowa around the noon hour Wednesday. Snow will be continue to stick around eastern Iowa through much of the afternoon on Wednesday. The good news is that winds will not be strong during this event, so reduced visibilities and blowing snow will not be an issue.
If you are traveling Wednesday, you might run into some rough travels across central and western Iowa early on, and most of the day across eastern Iowa. Before heading out, you can check 511ia.org for all the very latest road conditions. Of course, we will continue to have all the very latest details on our Facebook and Twitter pages, and right here at www.iowachase.com.
