Todays weather in Philadelphia - Monday - 25 May 2026

Philadelphia weather on Memorial Day is not cooperating. Today's philly weather forecast calls for patchy fog, oppressive humidity, and a 78% chance of showers and thunderstorms throughout the day. The high stays right around 74°F — warm but not sunny — with nearly calm southwest winds keeping the air feeling thick and close. Visibility will be reduced during both the morning and evening commute windows, so budget extra time behind the wheel and keep that umbrella within reach. Light, breathable layers are the call today; leave the sandals at home.The fog is not just a morning inconvenience. It lifts briefly and drifts back after 8 PM, though rain chances drop to around 12% overnight as the low settles near 62°F. The evening should be calmer, but roads may stay slick.The reward for getting through today is a genuinely excellent stretch of weather. Tuesday sees the fog burn off by mid-morning with afternoon sun and a high near 81°F. Wednesday climbs to 83°F under partly sunny skies. Thursday comes in clear and sunny at 79°F. Rain chances through the rest of the week stay mostly in single digits, with comfortable highs in the mid-to-upper 70s right through the weekend.If you have outdoor plans — a cookout, a gathering, a long walk — move them to Wednesday through Sunday. That window is wide open and worth the wait. Today's daily weather podcast gives you everything you need to dress smart, commute safely, and plan ahead for the week.This episode includes AI-generated content.
