There was a rare weather phenomenon that took place in eastern Nebraska Monday. National Weather Service Meteorologist Brian Barjenbruch says a narrow band of heavy snow stretched from Norfolk south to I-80 near Seward. It was caused by industrial steam produced by two plants in Norfolk.
Barjenbruch says, “Extra steam being introduced into the atmosphere. The temperatures were just perfect. We already have quite a bit of moisture in the atmosphere already. It just set up a scenario where the extra steam produced a plume of snow. it is very similar to lake effect snow you see around the Great Lakes.”
The band of snow was about 20 miles wide.
Barjenbruch says this is very rare but has happened before. He says there are some meteorological research papers written about it in the 1970’s. Conditions have to be just perfect in terms of temperature and moisture for it to happen.
