Plan on occasional blizzard conditions mainly west of U.S. Highway 63 tonight into Monday. A passing cold front will produce strong northwest wind gusts of 35 to 45-mph across northeast Iowa and southeast Minnesota tonight, continuing into Monday. The combination of the wind over a deep snow pack and additional fresh falling snow showers accumulating to 1 to 1.5 inches will produce considerable blowing and drifting snow. As a result, expect occasional blizzard conditions mainly west of U.S. Highway 63, with occasional white outs occurring east to the Mississippi river tonight into Monday. Travel is likely to become severely impacted.
A winter weather advisory remains in effect from 7pm this evening to 6pm Monday. Expect snow to develop around 7pm and then diminish around 6pm Monday. Snowfall accumulations of up to 1.5 inches are expected.
Winds gusting as high as 40-mph will cause areas of blowing and drifting snow, especially on ridge tops and in open areas. In addition, areas of poor visibility are expected. Plan on slippery road conditions, including during the morning commute on Monday.
A winter weather advisory for snow means periods of snow will cause primarily travel difficulties. be prepared for snow covered roads and limited visibilities, and use caution while driving.
