Pennsylvania – Cold air settles into the river valleys this morning, and damp roads glisten under gray skies. That quiet chill is the opening act to a much more disruptive winter stretch taking shape across western Pennsylvania.
A Winter Storm Watch is now in effect from Saturday evening through Monday afternoon for Pittsburgh and much of western Pennsylvania. According to the National Weather Service in Pittsburgh, a developing storm system is expected to bring periods of moderate to heavy snow, creating the potential for major travel impacts late this weekend.
Today stays relatively calm, though slick spots are possible early as road temperatures hover near freezing. Skies partially clear later, with highs reaching the mid-30s. That brief improvement fades quickly as colder air deepens Friday night. Overnight lows fall into the single digits, setting the stage for rapid accumulation once snow begins.
Snow chances increase Saturday afternoon, then ramp up Saturday night. Steadier snow is likely overnight into Sunday, with snowfall rates occasionally reducing visibility across the Pittsburgh metro. Travel along I-79, I-376, I-80, and secondary roads could become difficult to impossible during heavier bands.
Sunday remains active, with snow continuing through much of the day. Temperatures stay locked below freezing, limiting melting. Any brief lulls may be misleading, as untreated roads and bridges could remain snow-covered and icy. Gusty winds may further reduce visibility at times.
Snow may linger into Sunday night before tapering Monday. Morning travel could still be impacted by lingering snow and refreezing. Officials urge residents to complete preparations early, limit unnecessary travel, and keep winter safety kits ready.
Looking ahead, the broader pattern stays cold. Below-normal temperatures persist into next week, and additional storm chances remain possible as active weather tracks across the Midwest and Appalachians.
