URGENT: Light Snow Hits Northwestern PA; Bitter Cold Ahead

UPDATE: A winter weather alert is in effect as light snow begins to blanket parts of northwestern Pennsylvania this afternoon. Accumulations of 1-2 inches are anticipated in Warren and McKean counties, creating potentially hazardous travel conditions.

As of now, snow showers are affecting the northwestern mountains, particularly along the Allegheny Front, where most areas are expected to see less than an inch of accumulation. Central Pennsylvania remains under cloudy skies, with temperatures plummeting below freezing.

The National Weather Service issued an air quality alert on Saturday at 3:30 p.m. for several counties, including Dauphin, Lebanon, Cumberland, York, and Lancaster, which will remain in effect until Monday at midnight. Residents are urged to take precautions against the biting cold that will persist into the week.

Expect daytime highs to stay below freezing on Monday, with nighttime lows dropping into the single digits and low teens across central Pennsylvania. Authorities recommend protecting vulnerable pipes and ensuring adequate heating to cope with the frigid conditions.

Looking ahead, a high-pressure system will bring dry weather on Monday, but another clipper system is projected to move through on Tuesday, potentially leading to light snow across the northern tier of the state. This active weather pattern is expected to continue, with several systems bringing additional opportunities for winter precipitation from Wednesday into next weekend.

Weather models indicate that a more developed storm could impact the Mid-Atlantic region by Friday, reinforcing the need for residents to stay informed and prepared.

As we approach the official start of astronomical winter at 10:03 a.m. on December 21, 2023, winter weather is set to dominate the forecast. Stay tuned for updates as this developing situation unfolds.
