Saturday

High pressure will continue to give us mostly sunny skies (with a few periods of clouds) on Saturday. A disturbance dropping southward will move mostly west of our area after midnight Saturday with some showers and possibly some rumbles of thunder.

Highs 80º (Blue Bell) 81º (Philadelphia) Uncertainty: Low

The models are in fairly good agreement with this scenario. Here’s the Canadian RGEM total rainfall by Sunday morning—

09-20-24 18z Canadian RGEM total precip by Sunday morning. Once again, we rainfall diminishing as it approaches Philadelphia. (Click on image for a larger view.)

It wouldn’t surprise me if rainfall doesn’t make it into Philadelphia, which has been the case many times in recent months.

Sunday

The disturbance departs but the GFS keeps moisture at the lower levels. I’ll go with cloudy early, then partly cloudy/partly sunny, but the cloud cover may be more than currently expected.

Highs 74º (Blue Bell) 76º (Philadelphia) Uncertainty: Low
