The showers never materialized anywhere near Philadelphia yesterday. Except for an isolated shower near Reading, the entire area was dry. So much for the HRRR model, (which has been very good, but clearly not perfect.)
A cold front is moving towards us this morning, but its passage around noon will be dry, maybe with a few clouds. Cooler and low dew point air will be filtering in during the afternoon. Too dry aloft even for instability clouds. So it will be sunny and breezy. High 83.
