We got to 78° today and the showers were light and unimpressive.

A cold front is moving through this evening (Friday) and high pressure will build in for the weekend.  The trajectory of the high is to move to our northeast and by Sunday, a cooler, easterly flow will set up as the high departs .

Right now, the models keep skies sunny for Sunday, but it wouldn’t surprise me if clouds creep in during the day.

Update Fri 11 PM.Saturday will have some early cloudiness that beaks for sun 8-9 AM.

Saturday will be sunny. High temp between 50 and 52°.

Sunday is expected to be sunny but cool, although the easterly wind flow could result in clouds moving in.   High 46-48°

A wet system with secondary coastal low development will move in for Monday.

A brief update:  This morning’s models just coming in ( it’s Daylight Saving Time, so they’re in an hour later) are not consistent with the shower/thunderstorm threat today.

Most of the short range models have light showers developing between now and 2 PM  with the greatest threat north and west of Philadelphia.

The latest HRRR (High Resolution Rapid Refresh)  model is similar, keeping the showers mostly to the west of Philadelphia, although it has some showers moving into Philadelphia before noon and 2 PM.
