How to read a snowstorm forecast
The National Weather Service issued a snow forecast for Friday night, which was updated Saturday morning at 10:50 a.m. local time.
The NWS has snowfall amounts of up to six inches and a high of 4 to 5 feet.
The forecast calls for snow to fall as a dry layer.
The snow is expected to last for about a half hour, with some parts of the mountains to get more than one inch.
The forecast also calls for heavy snow on Interstate 95 in the Northeast, which runs from New Jersey to Maryland, and in parts of Pennsylvania, the forecast calls heavy snow in the Pittsburgh area.
The heaviest snow will be in parts around the Pittsburgh metropolitan area, including parts of Pittsburgh, Pittsburgh-area, and the suburbs, according to the NWS.
The NWS says a lot of people will need to prepare for a heavy snowfall, as snow accumulations can be up to four feet.
People should be cautious of driving, especially in the suburbs of Pittsburgh.
Snow accumulations and how much they will fall can be measured with a compass or with a snow shoe.
The weather service says the temperature will be between 6 degrees and 7 degrees in Pittsburgh, 5 degrees to 7 degrees on the Susquehanna River, and 4 degrees to 6 degrees in the Allegheny Mountains.
