Pennsylvania hills are wrapped in thick fog this morning, and visibility has dropped below a half mile across parts of State College. Headlights glow faintly along I-99 and Route 322 as drivers slow for damp pavement and limited sightlines. Temperatures hover near 34 degrees, close enough to freezing to keep bridges and untreated surfaces slick.
According to the National Weather Service in State College, areas of dense fog will continue through midmorning before gradual improvement. Rain becomes likely by late morning, with precipitation chances near 90 percent. Highs climb to 48 degrees, easing any early icy concerns but keeping roads wet through the afternoon.
Showers linger into tonight with lows near 40. Another round of steady rain develops Thursday, especially after 1 p.m., and continues into Thursday night. Rainfall amounts may range from a tenth to a quarter inch, with locally higher totals possible. Expect ponding in low-lying spots and reduced visibility during heavier bursts.
Friday stays wet with highs near 49 before drier air arrives Friday night. Saturday brings mostly sunny skies and highs near 45, offering a brief break.
By Saturday night, temperatures fall to near 31 and a chance of snow develops after 1 a.m. Even light accumulation could create slick patches into Sunday morning. This is peak flash-freeze season in central Pennsylvania, when melting moisture refreezes quickly after sunset.
Sunday turns colder with highs near 37 and additional snow chances. Early next week remains brisk before a 6–10 day outlook signals milder air building back toward Pennsylvania.
