Philadelphia, Pa. – Pennsylvania kicks off the week with crisp mornings and bright afternoons, giving residents a true taste of September fall weather. Commuters along I-95 will notice cooler starts, but sunny skies will dominate the drive into Tuesday and beyond. The stretch of mild weather keeps travel smooth, but residents should prepare for chilly evenings dipping into the 50s.
According to the National Weather Service in Mount Holly, Tuesday’s high will reach near 76 degrees under mostly sunny skies. Overnight lows drop to about 57, with light northeast winds near 5 mph. The clear pattern holds steady through midweek, offering dry conditions for road travel, outdoor work, and school activities.
By Wednesday, partly sunny skies keep highs near 72, but evening temperatures fall quickly. Those attending evening events or practices should pack an extra layer. Thursday brings the warmest day of the week with highs around 81 before another cooldown Friday into the upper 70s. The extended stretch of dry weather benefits outdoor construction and early harvest work, but also means lawns and gardens may need extra watering.
For drivers, the stable conditions mean no major travel disruptions, though reduced visibility from morning sun glare along I-95 and Route 76 could slow commutes. Residents are advised to use caution during early morning hours.
Looking ahead, the quiet pattern lasts through the weekend with highs holding in the upper 70s and lows in the mid-50s. Another stretch of dry and sunny weather sets the tone for September’s first full week.
