Central Pennsylvania residents can expect a cool evening transitioning to a more unsettled weekend with increasing chances of showers and thunderstorms, particularly late Saturday and Sunday.
A rare cool night for mid-July will give way to warming temperatures and rising humidity. Scattered showers are likely to develop Saturday afternoon, with the southern and western regions of the state having the highest probability of precipitation. A warm front moving northeast will bring increasing moisture, with potential for heavier downpours in the southeast part of the coverage area.
Sunday presents a higher risk of gusty storms and heavy rainfall as a cold front pushes across the region. Temperatures will range from the upper 70s to mid-80s, depending on cloud cover. Dewpoint values are expected to climb, creating muggy conditions with potential precipitation amounts between 1.5 and 1.8 inches across most areas.
Following the weekend system, a significant pattern shift will bring cooler, drier air for Monday and Tuesday. Residents can expect lower humidity, abundant sunshine, and a noticeable breeze. Daytime temperatures will remain moderate, providing a brief respite from typical mid-July heat.
Looking ahead, long-range forecasts suggest a return to heat and humidity by mid-next week. An expanding upper-level ridge is anticipated to bring rising temperatures and increased chances for afternoon and evening thunderstorms.
Residents should stay weather-aware, particularly during Saturday afternoon and Sunday, when shower and thunderstorm activity is most likely. Light rain gear and the ability to seek shelter quickly are recommended during these periods.
