State College, PA – A mostly quiet weekend will give way to an active and wet week across Central Pennsylvania, with repeated chances for showers and thunderstorms beginning Monday night. The impending pattern change signals a shift toward warmer, more turbulent summer weather that will likely impact travel and outdoor plans, including the Juneteenth holiday.
According to the National Weather Service, the most significant weather arrives late Monday and intensifies mid-week. While Sunday and Monday will see lower chances for rain, the probability for showers and thunderstorms jumps to 70% Monday night. The threat peaks on Tuesday, with an 80% likelihood of rain and possible thunderstorms, creating the potential for difficult travel conditions.
Residents should prepare for wet commutes, especially along Interstate 99 and U.S. Route 322. The combination of increasing moisture and rising temperatures, which are expected to climb from the upper 60s on Monday to a high of 85 degrees by Wednesday, will fuel the daily storm activity. This unsettled weather will continue into the Juneteenth holiday on Thursday, which holds a 70% chance of showers and thunderstorms.
Anyone with outdoor plans should build in flexibility and have a way to receive weather alerts. While no advisories have been issued yet, this could change as the systems organize. The pattern of afternoon and evening storms is expected to continue through the end of the workweek.
Five-Day Outlook for State College:
- SUNDAY: High near 66°F, Scattered showers and patchy fog.
- MONDAY: High near 69°F, A chance of daytime showers.
- TUESDAY: High near 75°F, Showers and thunderstorms likely.
