The primary areas at risk include the Ohio Valley and Pennsylvania, with the BGE service area also under threat. Damaging winds and hail are the main concerns, with the potential for isolated tornadoes as mentioned by NOAA/SPC. The risk is highest on Wednesday, with an 80% chance of severe weather during the late afternoon and early evening. Residents in these areas should prepare for possible power outages, property damage, and hazardous travel conditions due to strong winds and hail. The risk of severe weather is expected to persist through Thursday, though the intensity may decrease if the squall line arrives later in the evening.
