CWS Forecast: Southeast Pennsylvania

Today may be the first day of autumn, but the weather could not be further away from that at the moment, with sunny skies and summer like temperatures being caused by a stationary ridge of high pressure over much of the Eastern US.  This pattern is unlikely to change anytime soon, with heat only expected to increase once the weekend passes, with more humid conditions expected.  There is a small chance for rain on Tuesday, but it is unlikely to provide much relief from the warmth, cooler temperatures not expected to come before Thursday at earliest.
