Snow is possible in the Philadelphia overnight Thursday, creating the potential for a slick Friday morning commute.
The area can expect light snow from Thursday evening through about daybreak Friday, with the precipitation tapering off by the commute.
About two to three inches are expected for Philadelphia, with lesser amounts north and west of the city and the potential for up to four inches in parts of central New Jersey, according to the National Weather Service. Those amounts are slightly higher than initially forecasted.
A winter weather advisory is in place from 8 p.m. Thursday through 6 a.m. Friday.
"We are expecting a relatively quick shot of light snow overnight with most locations receiving an inch or two," a weather service forecast discussion said Thursday morning.
Any accumulating snow could lead to slippery conditions for the Friday commute. Overnight lows are expected to drop into the high 20s.
People should be prepared for snow-covered streets, slick conditions on untreated roads and limited visibility, the weather service said.
Small amounts of snow are expected late Thursday and early Friday along the Interstate 95 corridor from Washington, D.C., to Boston, leading to potentially slippery travel conditions throughout the corridor, according to AccuWeather.
There's a possibility of more snow Saturday, particularly near the coast, though forecasts indicate the chance of snow falling then in Philadelphia and the immediate surrounding area is low.
A Code Blue alert is in place through Tuesday morning, as cold temperatures are expected to persist into early next week.
High temperatures for Saturday through Monday are expected to be in the high 20s or around 30, and overnight lows could dip into the teens.
