How cold can it get when there is a blizzard?

Is wind associated with blizzards?
Blizzards are dangerous winter storms that are a combination of blowing snow and wind resulting in very low visibilities. While heavy snowfalls and severe cold often accompany blizzards, they are not required.
How does wind affect blizzards?
Warm, rising air is needed to form clouds and cause precipitation: warm air has to rise over cold air for a blizzard to form. Winds can either pull down cold air towards the equator from the poles and bring warm air towards the poles from the equator.
How can you tell if a blizzard is coming?
wind gusts over 35 mph. visibility of less than a quarter-mile (though if you’ve ever been caught in a blizzard, you’ll probably swear it’s closer to a few inches) duration of at least 3 hours. temperature below 20°F (-7°C)

Sustained high winds and temperatures far below freezing exacerbated the dangerous situation. In New York, winds averaged 40 miles (65 km) per hour and gusted up to 80 miles (130 km) per hour. The winds demolished power and telegraph lines and resulted in snowdrifts as high as 50 feet (15 metres).

The term blizzard describes a severe winter weather condition (violent snowstorm) characterized by strong winds, cold temperatures, and reduced visibility due to falling or blowing snow.
What happens to the human body during a blizzard?
Blizzard. The strong winds and cold temperatures accompanying blizzards can combine to create another danger. The wind chill factor is the amount of cooling the human body feels due to the combination of wind and temperature. During blizzards, with the combination of cold temperatures and strong winds, very low wind chill values can occur.
When does the NWS issue a blizzard warning?
…a severe snow storm characterized by strong winds causing blowing snow that results in low visibilities. When all the blizzard conditions are expected, the NWS will issue a blizzard warning. When just two of the above conditions are expected, a winter storm warning or heavy snow warning may be issued.
What makes a bomb cyclone turn into a blizzard?
Like all Northern Hemisphere cyclones, these storms move counter-clockwise around their cores. Bringing snow and/or rain, bomb cyclones are characterized by low pressure, large scale, and rapid development. Under the right conditions, bomb cyclones may turn into blizzards.
