Philadelphia residents can expect a changeable week ahead in terms of weather, according to the latest forecast. As reported by the National Weather Service, the city's weather pattern will start with mostly sunny skies today and a high near 51 degrees; however, there's a twist in the tale forecasted as the week progresses.

Temperatures tonight will hover around the 34-degree mark under increasing clouds, with calm winds maintaining the chill. A gentle pivot in conditions brings a chance of rain on Friday, starting after 1 pm with a 30% chance of precipitation, as daytime temperatures rise to a comfortable 56 degrees, accompanied by a south wind at 5 to 10 mph. However, residents looking forward to a dry Friday night might need to carry an umbrella as rain becomes likely, and the likelihood of precipitation shoots up to 70%.

A steady drum of rain is expected to beat down on the city come Saturday, with forecasters predicting a 100% chance of precipitation and new rainfall amounts between a half and three-quarters of an inch possible, as indicated in the National Weather Service. The rain appears set to continue into the night before tapering off before Sunday at 1 am. The weekend closure presents a 30% chance of rain before afternoon, followed by mostly cloudy skies and a high near 52 degrees.

The start of the new week brings a shift in the weather once more, clearing the skies for a sunny Monday with a high hovering close to 41 degrees. Nighttime temperatures early next week will dip to around the freezing mark, maintaining consistency with the cold, crisp theme. Residents have a mostly sunny Tuesday to look forward to, with highs reaching up to 46 degrees, and a pattern of part clouds, part sun will mark the middle of the week, with temperatures again pushing towards a mild 48 degrees on Wednesday.
