STATE COLLEGE, Pa. – Central Pennsylvania will feel its first true taste of late fall this week as a sharp cold snap drops temperatures into the 30s, bringing a widespread frost threat Thursday and Friday mornings. Residents across Centre, Blair, and Clinton counties should take precautions to protect sensitive plants and outdoor décor ahead of the chill.
According to the National Weather Service in State College, frost is expected to form early Thursday, with another widespread frost possible Friday morning. Skies will remain clear both nights, allowing rapid heat loss and strong cooling. Homeowners should cover flowers, disconnect hoses, and safeguard late-season crops as temperatures fall into the upper 20s and low 30s in rural valleys.
Despite the cold start, sunshine will dominate through Friday afternoon with highs climbing to the low 60s. The warm-up continues into the weekend as highs reach the upper 60s to near 70°F on Saturday — perfect for pumpkin patches, college football tailgates, and leaf-viewing drives through the Bald Eagle Valley and along U.S. Route 322.
Forecasters expect clouds to return late Saturday into Sunday, with scattered showers possible by Sunday afternoon. Temperatures will stay mild early next week, but crisp mornings will continue as fall colors peak across central Pennsylvania.
This week’s frost marks the start of the region’s transition to cooler, late-October air. Residents planning outdoor Halloween setups should prepare for chilly mornings and bright, calm afternoons heading into the final stretch of October.
