Snow is expected to spread north into Iowa Monday night and become widespread Tuesday and Tuesday night. A broad area of 6 inches or more of snow is likely with this storm. In addition, strong and gusty winds with gusts over 40mph will create considerable blowing a drifting snow and possible lead to prolonged period of near whiteout conditions, especially in rural areas. Some uncertainty remains along the southeast edge of the watch into southeast Iowa pending any potential shifts in the track of the storm as the heavy snow band will develop just west of the rain and snow line.
The National Weather Service has issued a blizzard watch from late Monday night through late Tuesday night. Snow will lift into the area late Monday night into Tuesday morning. A brief break in the snow may occur before resuming Tuesday afternoon and night. A period of very heavy snow may occur with snowfall rates of 1 to 2 inches per hour possible. Strong and gusty northeast winds will develop by Tuesday and will create considerable blowing and drifting of snow and potential whiteout conditions.
Storm total snow accumulations of 6 to 12 inches with localized 14 inch amounts are expected within the heaviest band of snow. Northeast winds of 25 to 35-mph with gusts in excess of 40-mph will be likely. Visibilities in snow and blowing snow will be below one quarter mile with whiteout conditions possible.
Extremely hazardous travel conditions may develop. Travel may become nearly impossible at times. If you have travel plans during this time, consider alternative plans.
A blizzard watch means there is a potential for falling and/or blowing snow with strong winds and extremely poor visibilities. This can lead to whiteout conditions and make travel very dangerous.
