Philly Weekend Weather Forecast

A weak warm frontal pattern will develop today as high pressure moves slowly off to the east and the upper air trough responsible for the unseasonably cold weather finally de-amplifies.

With the return of somewhat milder air aloft, there is an expected development of mid-level clouds– altocumulus and altrostratus – that will give a continued grey, November feel to Saturday.

So Saturday will be mostly cloudy, some breaks of sun possible, a bit milder but still unseasonably cold with a high temp near 40.

Winds shift to the southwest tonight and milder temperatures are expected on Sunday with highs in the low 50s. There may be some low level clouds at times, but much more sun than Saturday.
