Philly Weekend Weather Forecast

Last Updated

The forecast has clarified for this weekend, and it’s looking very wet, especially according to the NAM model.

The upper air trough providing the cooler than average weather will remain entrenched aloft as high pressure in the northern Atlantic tries to build westward. As a result, an easterly/southeasterly flow from the ocean will converge with the dry, cool upper flow of the trough over us, creating a retrograding coastal warm front for the next few days.

The Shore and areas south appear to be in the maximum convergence zone and will have the most clouds and rain. The GFS has depicted areas west of Philadelphia to be among the dryer areas, although the exact placement of the moisture convergence is difficult to determine.

Sat 8/2: Heavy rain during the morning ending late morning. Some brightening skies afternoon with a chance of a shower. High 79.

Sun 8/3: Cloudy, some bright spots mid-day with a chance of showers especially afternoon. Humid. High 81.
