Pennsylvania – The crunch of frozen ground echoed early Monday across central Pennsylvania as temperatures dropped into the teens. In State College, the air felt biting and still, with clear skies setting the stage for a fast-developing winter pattern that could complicate travel ahead of Christmas.
According to the National Weather Service in State College, clouds increase today with highs near the upper 30s. Snow develops later, then mixes with sleet as moisture spreads in. Accumulations stay light, but even a thin coating can create slick roads, especially on untreated surfaces and elevated areas.
Conditions deteriorate quickly tonight. Snow and sleet become more likely, with a risk of freezing rain before temperatures rise Tuesday. A light glaze of ice is possible atop snow, particularly across Centre, Clearfield, and Clinton counties. Drivers along I-99 and Route 322 should prepare for reduced traction and slower travel through Tuesday morning.
By Tuesday, temperatures climb into the mid-40s, allowing precipitation to change to rain. That shift helps melt snow, but it introduces another hazard. Wet roads may refreeze late Tuesday night as temperatures dip back toward freezing, increasing black ice concerns during early morning travel.
Wednesday brings a brief break with partial sunshine and highs near the low 40s. Attention then turns to Christmas Eve, when clouds thicken again and rain chances return. While significant snow is not expected by then, lingering cold ground could still create slick spots during early travel hours.
Residents should plan ahead now. Allow extra travel time, check road conditions before heading out, and keep winter safety kits in vehicles. Winter is settling in across central Pennsylvania, and small changes can make a big difference. Are roads slick where you are this morning?
