Snow and wind are a dangerous combination, but the snow doesn't always have to be falling from the sky to cause poor visibility.
A typical blizzard occurs when heavy snow is falling during windy conditions, causing poor visibility for an extended period. Ground blizzards also include strong winds and reduced visibility, but the source of snow is mostly or completely what has already accumulated on the ground.
In order to meet blizzard criteria, sustained winds or frequent gusts of at least 35 mph and visibility under a quarter of a mile are required for at least three straight hours.
Arctic cold fronts are a big contributor to ground blizzard formation, which brings a drop in temperatures along with increased winds. These are especially common in the Great Plains during the winter months.
As the strong winds develop, any recent or fine snow on the ground can easily be lifted into the air, which can quickly cause visibility to drop for drivers and anyone caught outdoors. This is why you must stay aware of the forecast, even if the forecast is dry.
