snowy scene Tuesday morning across the state
Hoosiers across the state wake up to a snowy scene, or even just snowflakes flying around. Areas in northern Indiana recorded measurable snowfall. All this snow is lake effect snow.
What is lake effect snow?
The National Weather Service’s definition of lake-effect snow is “snow that occurs when cold air, often sourced from Canada, flows over the open waters of the Great Lakes.” The cold air brushes the warmer, unfrozen waters of the Great Lakes. The heat and moisture are transferred to the atmosphere, the warm air rises and clouds form and grow into narrow bands that can produce heavy snowfall very quickly. Wind direction is crucial when it comes to determining where snow will fall.
Snowfall totals in Indiana
