Philadelphia is starting Sunday with clear skies, a chilly 43 degrees at the airport, and patchy frost still possible before 9 a.m. The payoff is a sunny afternoon near 66, with no rain and almost no wind.
A Frost Advisory remains in effect for Philadelphia and nearby parts of Southeast Pennsylvania through 9 a.m. Sunday. The National Weather Service says frost could harm sensitive outdoor plants, so gardeners with tender vegetation still outside may want to cover it before the morning chill fades.
Sunny Sunday Leads Into A Warmer Monday
Temperatures should climb quickly after sunrise, reaching the mid-50s by late morning and the mid-60s during the afternoon. Sunday night stays mostly clear with a low near 42, followed by another sunny day Monday and a high around 70.
The updated outlook builds on Hoodline’s Saturday forecast, with the morning frost alert now the main concern for city residents. Tuesday should reach about 66, while Wednesday remains mostly sunny near 65.
Dry Fall Weather Holds Through Halloween
Thursday and Friday bring another warm-up, with highs near 70 and 74, respectively, under mostly sunny or sunny skies. Saturday, Halloween, looks mostly sunny with a high near 72, while the chance of rain remains essentially absent through the week.
For anyone heading toward Ocean County’s back bays or Sussex County, Delaware, spotty minor tidal flooding may linger Sunday even as water levels gradually ease. In Philadelphia, the bigger planning note is simple: grab a jacket early, then enjoy a long run of mild afternoons.
