Thursday will be the pick of the week, with partly to mostly sunny skies and temperatures climbing into the upper 70s in Philadelphia, making for a great afternoon at the ballpark. Conditions change quickly overnight, though, as showers move in after midnight.
Rain is expected Friday morning, along with much cooler air. Temperatures are forecast to fall through the day, with breezy conditions and a sharp drop heading into Friday night. By late Friday night, lows are expected to fall to around the freezing mark, and Saturday looks much chillier than Opening Day.
