There were sunny skies in New Jersey on Friday, but those who were out and about in the Garden State knew that the sun did little to warm the conditions.

Temperatures for most of the morning were in the teens. That did not stop those who had to go about their business outside.

Megan Franzi, of Roxbury, took advantage of her car’s remote start feature, warmed it up and stayed inside while waiting for the bus in Parsippany.

"I’m not waiting outside,” she said.

Others who had to be outside made sure that they dressed in layers. This is also the advice from the Mayo Clinic, which says dressing loosely and wearing three layers is recommended. The first layer should be of a material that helps keep you dry. The second layer goes over the first and should be made of an insulator like wool or fleece. The third layer should be worn on top and should be windproof and waterproof.

The Centers for Disease Control and Prevention says signs of frostbite include white or grayish-yellow skin, skin feeling unusually firm or waxy and numbness.

Temperatures in New Jersey are expected to remain cold over the next few days.
