After more snow Sunday, season-low temperatures are coming to Philly Monday

Delicate snowflakes painted Philadelphia white Sunday morning, leaving icy roads and sidewalks to shovel. The storm will also leave behind a cold holiday.

“We have only seen round one; round two is on its way,” said Paul Fitzsimmons, a lead meteorologist with the National Weather Service office in Mount Holly.

Through Sunday, Fitzsimmons predicted a total of 2 to 4 inches of snow, with the second wave of flurries picking up after 1 p.m., possibly mixing with rain after 2 p.m.

Rain is not certain, but there is a 70% chance of showers, according to the National Weather Service. Couple that with a cloudy day, winds around 5 mph, and temperatures in the mid 30s (35 degrees being the warmest Philly will see today), and drivers are in for some hazy driving conditions.

“Roads are icy today: People should exercise extra caution, leave extra time to leave wherever they are going, and drive slower than normal,” Fitzsimmons said.

The weather prompted PennDot to advise drivers to avoid unnecessary travel. Commercial vehicles must stay in the right lane, PennDot said.

Stick to the speed limit even if the roads seem treated, because at the moment, PennDot’s main goal is to only keep them passable, not completely free of ice and snow, the department said.

PennDot’s crews will continue to treat roads throughout the day, but there is a slight chance of more snow coming before 8 p.m., with temperatures dropping as low as 20 degrees, and a 20% chance of rain, according to the weather service.

Monday arrives a bit sunnier, and with no snow, yet colder than Sunday, Fitzsimmons said.

Skies are expected to be fully clear, with a low of 14 and a high of 35 degrees. Do be mindful of the wind, as the National Weather Service expects gusts as high as 20 mph by Monday night.

That low would be the lowest of the season so far, with an even lower 10 degrees forecast for Tuesday.

“It’s going to be cold overall, so bundle up,” Fitzsimmons said.
