Philadelphia, Pa. – Clouds building across southeastern Pennsylvania today could slow commuters and dim skies over Philadelphia as the workweek begins. Drivers along I-95 and the Schuylkill Expressway may notice reduced visibility during the morning rush. Keep headlights on and allow extra space on wet roads.
According to the National Weather Service, increasing cloud cover will dominate Monday with highs near 81 degrees before temperatures trend cooler. Philadelphia will dip to the mid-60s tonight before another cloudy stretch Tuesday. Conditions shift by Wednesday, OCTOBER 1, when sunshine and highs near 70 bring a clearer, fall-like pattern.
East and northeast winds will remain light but noticeable, adding a slight chill to mornings by midweek. Wednesday night lows could fall into the low 50s, reminding residents that October’s cooler air is setting in. By Thursday and Friday, mostly sunny skies and highs in the upper 60s to near 80 will help ease commutes and outdoor plans.
Travelers should prepare for changing conditions through early week, keeping umbrellas handy until Wednesday’s clearing. Outdoor workers and students should dress for variable temperatures—short sleeves early in the week and light jackets by midweek mornings.
The bigger story is the shift toward steady fall weather starting Wednesday, signaling more comfortable days for weekend plans. Sunshine dominates through Friday before a mix of clouds return Saturday.
Warnings are not in effect, but residents should watch for updates as the new month begins. October will start on a cooler, calmer note across Philadelphia.
