The frigid cold is back with a vengeance in Western Pennsylvania.

The National Weather Service’s Pittsburgh office issued a cold weather advisory for the region, urging people to keep pets indoors as much as possible, wear warm clothing and use caution while outdoors.

Cold wind chills as low as 15 degrees below zero could lead to hypothermia or frostbite without proper precautions, according to the NWS.

As a result, Pittsburgh will open its warming centers Tuesday. The following sites will be open as warming centers from 8 a.m. until 7 p.m.:

  • Beechview Healthy Active Living Community Center at 1555 Broadway Ave.
  • Greenfield Healthy Active Living Community Center at 745 Greenfield Ave.
  • Homewood Healthy Active Living Community Center at 7321 Frankstown Road
  • Sheraden Healthy Active Living Community Center at 720 Sherwood Ave.
  • South Side Market House Healthy Active Living Community Center at 12th and Bingham streets

Allegheny County announced that all of its winter recreational facilities — including the North and South Park ice rinks and the Boyce Park Slopes — will be closed Tuesday.

All programming and public sessions at those sites are canceled. Pre-purchased registrations will be automatically refunded, though refunds could take a few days to process, according to county officials.

High temperatures Tuesday will reach the teens, but it’ll feel colder, according to TribLive news partner WTAE. Winds will reach up to 30 miles per hour, leaving wind chills sub-zero throughout the day.

Several schools have announced closures, delays or shifts to remote learning because of the cold.

Temperatures are expected to improve a bit Wednesday, with highs in the 30s, according to a forecast from the National Weather Service.

WTAE warned scattered snow showers — expected to last Wednesday afternoon through Thursday morning — could impact the Wednesday evening commute and leave about an inch or two of accumulation.

More freezing temperatures and snow are possible over the weekend.
