Pennsylvania starts the day under a gray ceiling, with damp air clinging to valleys and fog softening the outlines of roads and ridgelines. Pavement feels slick early, and conditions are set to change quickly as winter reasserts itself across central Pennsylvania.
According to the National Weather Service in State College, rain develops mainly this afternoon following patchy morning fog. Temperatures peak near 40 degrees before colder air arrives this evening. As that transition happens, rain mixes with snow and briefly turns to snow showers, especially overnight.
In State College and surrounding Centre County, travel impacts are most likely later today and tonight. Routes like US-322 and I-99 may start wet, then develop slick spots as temperatures fall toward the upper 20s. Gusty winds increase through the evening, reducing visibility during snow showers and pushing colder air into the valleys.
By Sunday, snow showers remain possible, mainly during the afternoon. Accumulations look light, but brisk winds make it feel colder than the mid-30s suggest. Any untreated surfaces could stay slippery, particularly in shaded areas and higher elevations north of town.
Sunday night brings clearing skies and another drop in temperatures. Lows fall into the mid-20s, setting the stage for flash freezing where daytime moisture lingers. Bridges, parking lots, and sidewalks may ice up quickly after dark.
Early next week offers a brief reset. Monday turns mostly sunny with highs near the upper 30s. Temperatures moderate into the 40s by Tuesday before another chance of rain arrives midweek, followed by a renewed risk of freezing precipitation late Wednesday night.
Plan errands earlier today, slow down once snow begins, and stay alert for changing conditions after sunset. Winter is still writing the schedule.
