STATE COLLEGE, Pa. — The morning air hangs still and cold over Centre County, the kind that silvers rooftops and crunches underfoot. Thin fog curls over open fields, and porch lights glow faintly through the haze. Central Pennsylvania begins this late October Sunday in full frost mode, the kind that signals fall’s final act before the chill of November.
Temperatures hover in the mid-30s, and widespread frost is expected through sunrise. Drivers should allow extra time — rural roads may feel slick from early dew and frost film. By mid-morning, sunshine breaks through, bringing a mild rebound to near 56°F. Winds stay calm, and the air feels crisp and dry — perfect for raking leaves or late-season yardwork.
Monday morning brings another strong frost, likely colder than today’s. Lows could dip into the upper 20s in outlying valleys. Gardeners should cover any remaining plants, and pet owners may want to limit early-morning outdoor time. The day turns bright and cool, with highs in the lower 50s under calm skies.
By Tuesday, sunshine holds firm, though clouds begin thickening late as the next system edges in from the Ohio Valley. A few showers develop Wednesday, increasing by Thursday with rain likely across the I-80 corridor. Despite the wet midweek stretch, severe weather isn’t expected.
Trick-or-treaters Friday evening can expect dry, chilly air — classic Halloween weather with mid-40s by dusk.
Models hint at a chillier November ahead, with the season’s first freeze potential growing stronger by next weekend.
