4th of July Philadelphia Weather Outlook

An active weather period through early Friday as a front slowly pushes through our area over the next few days. Adding to the weather mix will be tropical storm Arthur, which may intensify to hurricane strength. Regarding Arthur, all models track this storm well to the east of the Jersey shore. The nearby path of the storm may enhance the amount of water vapor available to fall as rain.
Beautiful weather returns for late Friday and lasts through the weekend.

Sat 7/5: Sunny and warm. Less humid. High 86

Sun 7/6: Sunny and warm. High 87

Philly Weekend Weather Outlook

The system that brough last night’s rains to Philadelphia has departed, but weak high pressure building in will only slowly reduce the humidity through Friday.

For this weekend’s weather, somewhat stronger high pressure will take hold over the weekend, giving us less humidity, but as you can see from the forecast surface weather map, areas of showers won’t be that far from our south and west over the weekend.   So partly cloudy/partly sunny skies are expected at this time with no rain.

A classic Bermuda high pressure system will finally establish itself this coming weekend, giving us seasonably warm (comparatively hot) weather for both Saturday and Sunday.  Dry conditions also expected.  High temperatures expected in the upper 80s.

However, before this system takes over for the weekend, a front and developing low pressure system will move through late Wednesday into Thursday.
