Keep the winter coat and the brush handy as an Arctic blast that ushered in dangerous cold could also bring some snow showers to neighborhoods.
The NBC10 First Alert Weather Team issued a First Alert for all day Wednesday as temps feel like the teens.
High temperatures will struggle to get out of the low 30s Wednesday. Add in wind gusts of 30 to 40 mph (the strongest gusts will be felt in South Jersey and shore points) and the "feels-like" temps will only warm to the teens by the afternoon.
"It's the coldest air of the season and our bodies are not adjusted to it so that's going to make it feel colder... It's like a January-type of chill earlier in the season," meteorologist Glenn "Hurricane" Schwartz said.
Before daybreak temps dipped into the teens and felt as low as 4 degrees in the Lehigh Valley.
With the frigid temps comes a chance of snow from around 9 p.m. Wednesday into early Thursday. A dusting is possible for Philadelphia and the immediate suburbs, with an inch or less possible in the outer burbs and 2 inches possible in the Lehigh Valley and Poconos.
Flurries are also possible Friday.
Local counties, including Camden and Montgomery, issued "Code Blue" declarations to ensure they get homeless people into shelters and out of the cold.
The dangerous cold only lasts through Wednesday but high temps will only get into the 30s into the weekend before a warm-up to the 40s by Sunday.
