The latest on Pa. snowstorm: Here’s when it’s supposed to start and stop

Update: Central Pa. snowfall totals: Up to 15 inches forecast in some areas

The anticipation is nearly over. As about half of the United States’ population prepares for what could be a historic snowstorm, the National Weather Service in State College issued its latest forecast Saturday morning.

Snowfall totals provided by the weather service cover a period from 7 p.m. Saturday to 1 p.m. Monday. From south central Pennsylvania to the northern New York line, forecasters are calling for between 10 and 15 inches of snow throughout the commonwealth.

Here is a breakdown of the snowfall predictions for parts of central Pennsylvania, updated at 10:30 a.m. Saturday:

• Harrisburg — 13.7”
• York — 11.3”
• Lancaster — 10.1”
• Chambersburg — 13.4”
• State College — 12.7”
• Williamsport — 13.4”
• Wellsboro — 13.2”
• Bradford — 10”

Snow could accumulate up to 18 inches, according to winter weather alerts issued by the NWS.

Anywhere from 8 to 13 inches of snow is predicted to accumulate in Philadelphia by Monday, and 9 to 16 inches of snow is expected in Pittsburgh, the NWS said.

For Harrisburg and surrounding areas, snow is expected to start falling after 3 a.m. Sunday with temperatures around 14 degrees. Snow will continue to fall throughout Sunday, which will have a high temperature of 22 in Harrisburg.

The snowfall will be heavy at times Sunday, sometimes exceeding 1 or 2 inches per hour, forecasters said. South of the Pennsylvania Turnpike, snow could mix with sleet or freezing rain on Sunday afternoon, cutting down on snow totals in some areas.

By mid-afternoon Monday, snow is forecast to stop falling in central Pennsylvania.

The arctic air contributing to the storm is forecast to remain during and after the storm, with real-feel temperatures possibly dropping below zero, especially into the evening hours.

PennDOT and the Pennsylvania Turnpike Commission scheduled vehicle restrictions across the state ahead of the storm.

“Travel will be very difficult to impossible. Widespread and prolonged travel disruptions are expected,” the National Weather Service said in a winter weather message issued to dozens of central Pennsylvania counties.

Harrisburg, like many other municipalities in central Pennsylvania, declared a snow emergency Friday. The city has nearly two dozen snow plows and hundreds of tons of salt at the ready.

Additionally, PennDOT announced all driver license and photo centers, including its full-service center in Harrisburg, will be closed Monday and Tuesday.

Pennsylvania Liquor Control Board also announced all its Fine Wine & Good Spirits locations will be closed Sunday.
