CENTER CITY (WPVI) --Bitter cold temperatures plus whipping winds made Monday the teeth-chattering, punch-in-your-gut type of weather that we have dodged so far this winter.
Those outside had some advice.
"Two layers on the bottom, four on top," said Derek Byrd. "It's really all you can do."
Action News found Byrd, a dog walker in Center City, and Lucy the dog ready to go.
Some students who were off today and wanted to take in the city sites were forced by the cold to change their plans.
Other students heading out to take part in the MLK Day of Service knew it was too important to stay home.
Meantime it was business as usual for many heading to work.
Outside SEPTA's Frankford Terminal, some were learning the hard way it's really cold out.
Others already knew the drill.
"It feels a lot colder than it is," said Robert Dotter of Northeast Philadelphia. "It feels about 5 or 6."
"I grabbed a different coat," said Deneen McCleary of Frankford. "We needed it."
The bitter cold came the morning after snow showers from Delaware County to Atlantic City left some roads slick and treacherous.
Action News found black ice on roads in Camden County and elsewhere.
"They're pretty slippery and the temperatures are dropping and it's pretty slick," said Ralph Pecca of Haddon Township.
Ice was being blamed for several minor crashes, including one on Grant Avenue in Northeast Philadelphia in which a motorist slid into a utility pole.
This, despite the fact that 162 PennDOT trucks spent Sunday spot-salting roads as temperatures began to tumble.
"We're concerned about later on, when the temperature starts dropping because the roads are wet, we're going to start getting icy spots," Peter Scerati of PennDOT said Sunday afternoon.
And for the first time this season, ice-melting products were flying off store shelves, including Fairmount Hardware in Philadelphia.
"People were actually getting two bags of 50-pound bags of the salt," said manager David Adams. "I don't know if they were afraid that we were going to run out, but we won't."
Earlier Sunday, falling flakes set the scene for Diana Sterin's engagement photos.
Many say the unexpected snowfall was the perfect snow, picturesque and not sticking to the ground.
"I've been checking the weather all week and I saw 50s with rain, and I didn't expect to have any snow today," said Vinny Menichetti of Bucks County. "It was unbelievable that it snowed today."
"It's perfect, perfect white snow," said Sterin.
It was a white out on the running trails along Kelly Drive, and Alex Fisher took advantage.
"When things start freezing, it becomes difficult to get out and run on a Sunday, and now all of a sudden it's snowing and it's not going to be sticking just yet," said Fisher of South Philadelphia. "I wanna get out when i can."
