Wednesday was a day of cold weather that included a breathtaking snow squall and an impressive sunset to the Greater Red Bank Green.

Thursday morning brought bitter cold: at 6:30 a.m., the air was at 3 degrees, and wind made it feel like 16 below zero, according to the National Weather Service.

It’s all courtesy of a polar vortex gripping a large portion of the United States and causing multi-hour flight delays at airports. 

The cold was expected to linger through Friday, prompting Governor Phil Murphy to warn New Jerseyans to “stay inside” for safety.
