November blows in with a highly amplified trough and an embedded upper air disturbance that may bring snow showers around daybreak Saturday. No accumulation expected. Much uncertainty, but a cold and windy Saturday is expected.

Clearly I misread the 850 mb relative humidity forecast for today. No clouds! Not my best forecast. 🙂 No clouds expected tomorrow either. Ignore that man behind the curtain.
Philly Weekend Weather Forecast

Our weather this weekend will be dominated by an upper air trough that will almost cut off over the northeast. There isn’t much moisture but the pool of cold air aloft will cause some cloudiness each afternoon.
The amount of cloudiness may be greater than is currently being forecast and may reduce the high temperatures each day. The upper air flow will also cause windy conditions, especially Sunday morning.
For Saturday, sunny early, then periods of cloudiness early afternoon. Breezy. Clouds dissipate late afternoon. High 63.
For Sunday, very similar conditions, a bit windier in the morning before some cloudiness develops in the afternoon. High 64.
