Philly Weekend Weather Outlook

A poorly defined series of disturbances will affect our weather during the first part this coming weekend. A stronger system brings rain likely for Sunday.

Friday will likely have showers at some point during the day, but the GFS and the NAM differ about QPF, with the GFS wetter than the NAM.

Saturday will likely be a mix  of clouds and some sun.  The NAM is again drier than the GFS and  I’m leaning towards the drier NAM.

Both models predict heavy rain for Sunday, especially in the afternoon.  (But that sort of forecast didn’t pan out this past Monday, as most the rain moved east into NJ, predicted by the NAM.)

Will update late Friday.
