PITTSBURGH (KDKA) -- People were urged to stay safe and warm indoors during the bitter cold temperatures Saturday.
The National Weather Service issued a Wind Chill Advisory for the entire day Saturday, along with a Lake Effect Snow Advisory in Forest, Mercer and Venango counties. The Wind Chill Advisory was cancelled for Allegheny County early Sunday, but it was still in effect for many surrounding counties.
The NWS also reported Saturday morning that a dangerous snow squall would affect central Clarion, Mercer and southwestern Venango counties, including sections of I-79 and I-80. Pennsylvania state police said the squall played a role in causing a fatal pile-up on I-78 Saturday morning.
KDKA's Jon Burnett reported seeing light snow showers and flurries throughout the area Saturday morning, with an inch of accumulation expected later in the day and possibly two inches in areas north of I-80. Temperatures will only reach about 10 or 12 degrees later in the afternoon and evening, and they could drop to only about 2 or 3 degrees above zero overnight.
According to KDKA-TV Meteorologist Ron Smiley, the coldest night of the year so far was on Jan. 13, with the low in Pittsburgh falling to 3 degrees. Temperatures on Sunday could possibly match that low, with a low of 3 degrees and a high of 20 degrees.

West Penn Hospital Emergency Room Doctor Morgan Garvin advises anyone in the outdoors that they are a candidate for frostbite.
"Somebody who is not properly dressed out in this weather for more than 30 minutes, I would expect could start to see some damage from frostbite," she said.
Warming centers are open throughout the city and the surrounding area.
The bitter cold has prompted some closings, including the closure of the Pittsburgh Zoo & PPG Aquarium.
