STATE COLLEGE, Pa. – Rain will dampen Columbus Day plans across central Pennsylvania before sunshine and mild fall air return midweek. Early Monday brings steady drizzle and gray skies, but a brighter pattern is on the way. Drivers along U.S. Route 322 and I-99 should use caution during the morning commute as wet roads and patchy fog linger.
According to the National Weather Service in State College, scattered rain showers will fade by Monday afternoon as cooler air moves in from the north. Skies will gradually clear Tuesday with highs near 69°F, followed by crisp, sunny weather through the rest of the week.
