Philadelphia Weekend Weather Outlook- Mon PM
Much uncertainty with the upcoming weekend forecast, as the models have changed considerably since yesterday. The basic scenario involves the development of a deep upper air trough in the Great Lakes area, associated the passage of a cold front on Friday.
Things were to clear out for Saturday and Sunday. However, the latest GFS model stalls the frontal system, allowing the development of a coastal low Saturday night into Sunday. The would result in a cold, windy rain for later Saturday into Sunday. Too early to be sure on this one. Will keep an eye on this.

Sat 10/17: Tentative: Cloudy with a chance of showers, especially later in the afternoon. Breezy and cool. High 55.
Sun 10/18: Tentative: Cloudy with rain and wind. High 56.
