Strong thunderstorms are expected to impact south-central Pennsylvania on Wednesday, with the potential for heavy rain, lightning, and gusty winds. The National Weather Service has classified Wednesday as an "Impact Day," indicating weather conditions that could disrupt daily routines. The primary threat window for severe storms is between 1 p.m. and 11 p.m., with scattered thunderstorms likely to develop across the region. Wednesday morning will feature a few rain showers, but the main activity is expected in the afternoon as thunderstorms move into the Susquehanna Valley from west to east. These storms could range from strong to severe, with the possibility of damaging wind gusts, frequent lightning, and brief heavy downpours. A brief respite from rain may occur in the early evening, but a cold front moving through later in the day will bring another round of scattered showers and thunderstorms, with isolated severe storms possible. Overnight into Thursday morning, showers and thunderstorms may linger, but temperatures will drop significantly behind the cold front. Highs on Thursday are projected to fall into the upper 40s, with lows in the upper 20s. The cold air will bring blustery winds, marking a sharp contrast to the warm conditions earlier in the week. The Storm Prediction Center has placed the entire Susquehanna Valley under a Slight Risk (Level 2 of 5) for strong to severe thunderstorms. This risk is driven by a strong cold front interacting with powerful upper-level winds, creating unstable conditions. While the likelihood of tornadoes and large hail remains low, these threats cannot be entirely ruled out. Temperatures on Tuesday night will remain in the low 50s, with increasing cloud cover. Wednesday’s highs are expected to reach the low to mid-70s, nearing the record high of 76 degrees set in 2021.#national_weather_service #storm_prediction_center #susquehanna_valley #storm_team
