Philadelphia Weekend Weather Forecast - Fri AM
A frontal boundary moved through last night and stalled just to our south. It will serve as a trigger for thunderstorms, mostly in areas south of Philadelphia today. The front will sink a bit further south. An easterly wind will cool down temps, but will bring in considerable cloudiness on Saturday. Low pressure developing on the stalled front will bring another frontal boundary through Sunday morning. Gradual clearing on Sunday.
Sat 6/11: Damp conditions and possibly light sprinkles in the morning, then mostly cloudy with a chance of light drizzle or spotty showers, increasingly likely in the afternoon. High 80.
Sun 6/12: Clouds break late morning for increasingly sunny skies. High 86.

Philadelphia Weekend Weather Update - Sat AM
A continued somewhat blocked upper air pattern will give us cooler and less humid weather for the weekend. The surface pattern is poorly defined and there are differences between the NAM and GFS models, especially for Sunday's forecast. The NAM has considerably more clouds and showers than the GFS. I'm going with the the more optimistic GFS although confidence in Sunday's forecast is lower than usual.
Update: The sun should break out, before more clouds move in during the afternoon. High resolution NAM shows showers, especially north and east of the city, later this afternoon.
Sat 6/4: Partly sunny with increasing cloudiness during the afternoon. Showers likely in the evening. High 79.
Sun 6/5: Clouds and a possible light sprinkle early morning, then party sunny. Chance of a late afternoon shower. High 77.
