...STRONG WINDS, SNOW, AND BLOWING SNOW LATER TODAY... .A fast moving storm system will bring snow showers and strong northwest winds from around midday into early tonight. Winds gusting to near 50 mph at times will blow both falling snow and snow already on the ground, greatly reducing visibility with near-blizzard conditions possible at times. The reduced visibility, strong crosswinds, and snow covered roads will make travel very dangerous. * WHAT...Snow, strong winds, and blowing snow expected. Snow accumulations around an inch or less. Winds gusting as high as 50 mph. Visibility may fall below a quarter of a mile at times. * WHERE...Portions of northern into northeastern Iowa. * WHEN...From 11 AM this morning to 11 PM CST this evening. * IMPACTS...Plan on slippery road conditions and strong crosswinds. Blowing snow will significantly reduce visibility, with near-blizzard conditions possible at times. This combination will make travel very dangerous and will impact the evening commute. Gusty winds could also bring down tree branches.

Slow down and use caution while traveling. For the latest travel conditions, check the Iowa 511 app, www.511ia.org, or dial 511.
