UNDATED -- Blizzard or blizzard-like conditions are forecasted for many parts of Oklahoma Tuesday.
So, what is a blizzard really?
According to the National Weather Service, a storm must meet the following three conditions to be considered a blizzard:
Wind- Sustained winds or frequent gusts of 35 MPH or greater.
Visibility- Considerable falling snow and/or blowing snow which will frequently reduce visibility to 1/4 mile or less.
Time- The above must occur for at least 3 hours.
It doesn't have to be snowing to be considered a blizzard. With strong winds, already fallen snow can reduce visibility.
