Snow showers and strong winds will surge from northwest to southeast across Iowa this evening and overnight. Combined with the deep snow pack in place across much of northern Iowa, this will lead to blizzard conditions at times especially late tonight into Monday morning. Travel will become dangerous during this time as snow blows across roads and visibility drops to near zero.
The National Weather Service has issued a blizzard warning from 7pm Sunday evening, to 6pm Monday evening. Snow will begin to fall this evening and will continue through Monday afternoon. The worst conditions will occur overnight tonight into Monday morning.
Snowfall accumulations will be generally less than 2 inches, but with locally higher amounts possible. Winds will be out of the northwest at 25 to 35-mph, with gusts to near 50-mph at times. Visibilities may drop below one quarter mile for an extended period with near whiteout conditions possible, especially during snow showers.
Considerable blowing and drifting snow, combined with very low visibility, will make travel dangerous and even impossible in some areas.
A blizzard warning means severe winter weather conditions are expected or occurring. Falling and blowing snow with strong winds and poor visibilities are likely. This will lead to whiteout conditions, making travel extremely dangerous. Do not travel. If you must travel, have a winter survival kit with you. If you get stranded, stay with you vehicle.
