Philadelphia is heading into a crisp, sunny Friday, with temperatures climbing from the upper 40s this morning to about 62 degrees by afternoon. The bigger weather story arrives after sunset: a clear, colder night that could bring patchy frost before dawn Saturday.

Sunny Friday, Colder After Dark

North winds will run around 10 mph, with gusts reaching 25 mph, and rain is not expected. According to the National Weather Service, temperatures are expected to cool overnight Friday.

The low should settle near 37 degrees, with patchy frost possible after 3 a.m. Saturday. Saturday morning may start cold enough for frost in some spots before sunshine pushes the high to around 63, while Sunday brings another frost risk before a high near 66.

A Gradual Warm-Up Takes Over Next Week

Monday should be the warmest day of the stretch, with sunny skies and a high near 69 degrees. Tuesday and Wednesday bring highs around 72 and 65 degrees, respectively, while Thursday rebounds to about 67 under mostly sunny skies.

Anyone with cold-sensitive plants still outside may want to cover them before the overnight chill arrives. The sharpest frost risk is expected outside the urban core and north and west of the Interstate 95 corridor.

Shore Trips May Run Into High Water

For readers heading toward the Jersey Shore or Delaware beaches, minor coastal flooding is expected to continue in parts of Ocean County, New Jersey, and Sussex County, Delaware, through Friday night. A small craft advisory also remains in effect for nearby ocean waters, where seas may stay elevated into Saturday.
