Wintry-mix threat fades in immediate Philly area, but icing possible north and west of city

A winter-weather advisory remains in effect for counties north and west of Philadelphia until 10 a.m. Tuesday, and the National Weather says some icing is possible.

But Philadelphia and adjacent South Jersey have been removed from the advisory, which “has been knocked back a bit,” said Jonathan O’Brien, a meteorologist at the National Weather Service Office in Philadelphia.

Snow and mixed precipitation had been expected to begin during the morning, but it was repelled by layers of dry air at lower levels of the atmosphere, he said.

Meanwhile surface temperatures throughout the region were above freezing Monday afternoon.

Steady precipitation might hold off until after dark, O’Brien added, and temperatures could slip below freezing for a time, resulting in some ice accrual.

Regardless of what does or does not happen the rest of the day, more than 10 Chester County school districts and one in Delaware County announced early dismissals.

Brad Rudolph, a PennDot spokesperson, he said he expects about 170 trucks to spread salt throughout Monday and into Tuesday. Motorists can download PennDot’s 511 app to stay up-to-date with weather and traffic alerts.
