The National Weather Service says more snow has fallen on Allegheny County today than originally anticipated.
An initial winter weather advisory issued Friday night predicted 2 to 4 inches of snow today. But by noon, the county had received between 3.5 and 5 inches since the snowstorm began around 2 a.m.
Meteorologist John Darnley said the flurries had started to taper off and predicted no more than a couple hundredths of an inch falling after 1 p.m.
Another squall is expected to begin around midnight and drop no more than an inch before clearing by 11 a.m. Sunday, he said.
Looking ahead, preliminary assessments indicate that the region will likely experience a white New Year's Eve. Mr. Darnley said anywhere from one to two inches are expected to fall between 11 p.m. Monday and 5 a.m. Tuesday.
"It can be problematic in terms of people not being prepared and a lot of people being out," he said.
An Allegheny County emergency dispatch supervisor said no major vehicle crashes have been reported because of weather conditions.
Snowfall prompted Pennsylvania Turnpike officials to lower the speed limit to 45 mph this morning from the Ohio border to the Morgantown Interchange.
The restriction was only between the Ohio state line and the Blue Mountain Interchange early this morning but was later extended another hundred miles. The speed limit is now lowered on nearly 300 miles of the turnpike, from milepost 0 to 298.
No truck or trailer restrictions have been implemented.
Though light this morning, there were periods of heavy snow in the Pittsburgh area and freezing rain in Morgantown, W.Va.weather - mobilehome - homepage - breaking
