Winter Storm Slamming Pittsburgh: Latest Snowfall Estimates

PITTSBURGH, PA — A significant winter storm is hitting the Pittsburgh area, with snow already present in the metro area as of 9 a.m.

The latest from the National Weather Service is that Pittsburgh could see as much as six inches of snow. A Winter Weather Advisory is in effect from 1 p.m. Saturday until 1 p.m. on Sunday, but the weather service says the advisory could be upgraded to a Winter Storm Warning.

That warning already is in effect for areas along and south of I-70 for this afternoon into Sunday with the heaviest snow expected. Totals in the warning are most likely to be 6-8 inches, though up to a localized 12 inches is possible in high terrain or as the result of snow bands.

The weather service cautions that the most uncertainty in the advisory area is in Allegheny County, depending on how the storm tracks.

Frigid temperatures will accompany the storm. The low tonight is expected to be 12 degrees, with the high tomorrow only reaching 20.
