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.

The string of picture perfect weekends we’ve had recently will be broken Saturday, as both models have a weak surface low moving just to our south. Interestingly, this is the first weekend in awhile where there is disagreement between the NAM and GFS models- the NAM develops some showers in the afternoon, but the GFS just has cloudiness. Difficult to tell which will be correct.

Beautiful weather returns for Sunday.

Sat 6/21: Becoming cloudy in the afternoon, a chance of showers in the afternoon, especially south of Philadelphia. High 77

Sun 6/22: Sunny and warm. High 84
