Philly Weekend Weather

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

Weekend Weather Outlook

GFS Model Forecast for late Saturday
GFS Model Forecast for late Saturday

A weak frontal boundary will pass through Thursday or Friday, and will stall to our south.  Unsettled weather is expected for this weekend, although the latest models have backed away from a very wet weekend, keeping much of the shower activity to our south and west.

In fact, while there will be considerable cloudiness, some breaks of sun are possible and it currently appears that the weekend will be rain-free much of the time.

High temps will be in the low 80s with dewpoints near 60.
