Four to 8 inches of snow is possible Tuesday night for the Philadelphia area. The system will be brief — the snow is expected to stop by 1 a.m. Wednesday — but up to an inch of snow per hour is possible, according to the National Weather Service.

Timing

The heaviest snowfall will be between 6 p.m. Tuesday and 1 a.m. Wednesday.

“There might be some lingering light snow that kind of clears out by mid-morning,” said NWS Meteorologist Zack Cooper. “The rest of it should clear out.”

The snow could have an impact on morning commuters Wednesday. PennDOT is advising motorists to avoid unnecessary travel and to exercise caution when driving.

“Any traveling during the height of the snowfall could be slippery,” Cooper said. “The morning commute could be a little bit tricky, a little bit slippery even if the main snowfall has moved out of the area.”

Another system Wednesday is expected to bring mostly rain to parts of New Jersey and Delaware. A wintry mix is likely northwest of I-95 initially before transitioning to rain, according to 6abc.

The rain will move out early Thursday, and high temperatures are forecasted for a comfortable 48. Friday looks breezy and a bit cooler for the Eagles’ victory parade, but still a seasonal and sunny high of 38.

Biggest impacts

Philadelphia is predicted to receive three to 4 inches of snow Tuesday, while parts of Delmarva and South New Jersey could get up to 8 inches. Cooper says snow may mix with sleet and rain across portions of southern Delaware toward Cape May County, which could reduce the total snow amounts.

“The main place I think that would be an issue would be Sussex County,” he said. “That’s where we think the highest probability of mixing could occur.”

Winter storm warnings have been issued for most of Delaware and parts of South Jersey.

Code Blue is in effect until 9 a.m. Thursday to provide additional protections for people experiencing homelessness. City intake centers are open to help anyone who needs shelter. If you see a person who appears to be homeless outdoors during a Code Blue, call the city’s homeless outreach hotline at 215-232-1984.

Drivers are required to remove accumulated ice or snow from their vehicle, including the hood, trunk, and roof within 24 hours after the storm has ended. Drivers can be fined up to $1,500 if snow or ice is dislodged and strikes another vehicle or pedestrian causing death or serious injury.

In January, a winter storm hit the Philadelphia metro area, dumping up to 12 inches of snow in parts of the region. Philadelphia’s Streets Department had 350 pieces of equipment out treating the streets, and 500 city workers deployed to respond to the storm.
