The definition of a blizzard is:
1) Snow and/or blowing snow reducing visibility to 1/4 mile or less for 3 hours or longer
2) Sustained winds of 35 mph or greater or frequent gusts to 35 mph or greater.
With blizzard warnings in effect, Siouxland will likely sustain blizzard conditions throughout the overnight Thursday and into Friday… on top of piling on nearly a foot of snow.
As of 10 PM, Meteorologist Elisa Raffa measured ~2″ in the Sioux City metro. Sioux City is forecasted to get 6-12″.
