Philly Weekend Weather Forecast

An unsettled weather pattern is in store for this weekend as a result of surface low pressure moving over our area on Saturday from the west followed by weak low pressure lingering on Sunday.  The precipitation will be heavy due to high precipitable water and high dew points and it will be enhanced by an upper air impulse fueling the dynamics.

Saturday will start out with some sunshine, but clouds should move in during the morning, followed by  rain and thunderstorms moving in from the west as early as noon to 2 PM.  The rain continues into Saturday night and the models are suggesting that the rain could be heavy.  It will be very humid and warm. High temps will be about 85.

Sunday might be a bit  better, as some sunshine should break out, but scattered showers and thunderstorms still possible.  The showers will be scattered, more likely and more areal coverage in the afternoon.  Warm and very humid with high temps near 87.
