Pennsylvania wakes to gray skies and damp air rolling over Pittsburgh hills. Streets feel cool, and clouds hang low. Winter is lining up its next move, and travel conditions could change quickly by Friday.
According to the National Weather Service, temperatures start in the low 40s this morning. A quiet stretch follows, but moisture builds later. Roads remain dry early, though breezy winds may pick up by afternoon. Drivers should stay alert on I-376, I-279, and Route 28 as conditions evolve.
Clouds thicken Thursday, and rain develops by afternoon. Showers become steadier Thursday night, soaking roads across Allegheny County. Visibility may drop during heavier rain, especially during evening travel. Plan extra time if heading out after sunset.
By Friday, colder air presses in. Rain continues early, then temperatures fall into the upper 30s. Meteorologists are watching a possible rain-to-snow changeover by midday or afternoon. Accumulations appear light for now, but even brief snow could cause slick spots on untreated roads and bridges.
Winds increase Friday, making it feel colder than the thermometer suggests. Gusts may exceed 30 mph at times. If snowflakes mix in, visibility could drop quickly in bursts. Drivers should watch for sudden changes on elevated roadways.
Friday night turns colder, with lows near the low 20s. Any leftover moisture may freeze, creating black ice early Saturday. Parking lots, side streets, and on-ramps are most vulnerable.
This setup signals an early winter transition. While major snow is not expected locally, large storms impacting the Midwest highlight a developing winter pattern nationwide. Travelers heading west or flying should monitor conditions closely.
