Philadelphia woke to clear skies Tuesday morning, setting up a sunny afternoon with a high around 77. Light winds and comfortable humidity should make for an easy commute and pleasant outdoor plans. No weather alerts are in effect for the city.

The National Weather Service expects east winds near 5 mph Tuesday, with mostly clear skies continuing Tuesday night. The latest outlook is a much calmer turn from the flood-watch setup described in Hoodline's earlier forecast.

Sunny Skies Give Way To Midweek Warmth

Wednesday will stay sunny and warmer, with a high near 82 and light south winds. Thursday should reach about 85 degrees, while Friday is expected to reach near 82 under mostly sunny skies.

That stretch should remain mainly dry, although humidity will gradually increase as the week progresses. For anyone planning outdoor dinners, errands or neighborhood events, Tuesday through Friday offers the most dependable weather window.

Weekend Shower Chances Return

Saturday looks partly sunny, with a high near 77 and a 15% to 20% chance of showers. A chance of showers arrives Sunday, followed by a daytime high near 83.

Additional shower chances continue late Sunday, while Monday is expected to be sunny with a high near 77. Significant impacts are not expected at this point, but the umbrella may want a weekend cameo after enjoying a quiet week.
