Pennsylvania — Wet pavement, falling temperatures and the possibility of snowflakes could bring an early taste of winter to Pittsburgh this weekend.
After afternoon temperatures approach 63 degrees Wednesday, colder air will push lows toward freezing Friday night. By Saturday, rain could mix with snow before conditions gradually improve.
The changing pattern could affect weekend plans across Pittsburgh, Allegheny County and surrounding western Pennsylvania communities.
According to the National Weather Service, Pittsburgh faces a 90% chance of rain Thursday, followed by a 40% chance of rain and snow Saturday.
The transition comes as a large weather system pulls colder Canadian air across the eastern United States.
Thursday Rain Brings First Major Weather Change Thursday, November 12, looks especially damp across the Pittsburgh area.
Rain chances climb to 90%, with temperatures reaching approximately 51 degrees.
Northwest winds increase to 5 to 14 mph as colder air begins arriving.
Drivers along Interstate 376, Interstate 79 and Interstate 279 should prepare for wet pavement and occasional reduced visibility during steadier rainfall.
Thursday night temperatures fall toward 35 degrees, with rain remaining likely before 7 p.m.
Precipitation chances reach 60%, although additional rainfall amounts are expected to remain below one tenth of an inch.
Friday Temperatures Fall Toward Freezing Friday, November 13, brings another noticeable temperature decline.
High temperatures reach only 44 degrees, nearly 20 degrees below Wednesday's expected high.
A 30% chance of rain continues before 1 p.m., followed by mostly cloudy conditions.
By Friday night, temperatures fall toward 32 degrees.
That raises concerns about isolated icy patches where moisture remains on exposed surfaces.
Bridges, ramps and untreated pavement could become slippery if temperatures fall below freezing.
However, widespread flash freezing is not specifically predicted.
Saturday Snow Chances Enter Pittsburgh's Outlook Saturday, November 14, brings the weekend's most notable weather development.
The National Weather Service indicates a 40% chance of precipitation, including possible rain and snow before 1 p.m.
Rain chances continue afterward as temperatures climb toward 45 degrees.
For now, the local forecast does not specify measurable snowfall accumulation.
Still, even brief wet snow could surprise drivers during morning travel, particularly where temperatures remain close to freezing.
Residents should monitor updated forecasts before traveling through Allegheny County.
Sunday Brings Some Improvement Sunday, November 15, looks partly sunny, with highs near 47 degrees.
Temperatures fall toward 33 degrees Sunday night, keeping chilly mornings in the picture.
The Weather Prediction Center continues tracking a significant polar air intrusion across the eastern United States.
No specific tornado threat is indicated for Pittsburgh in the supplied outlook.
