Pennsylvania wakes up to damp pavement and a raw chill hanging over Philadelphia as steady February rain moves through the region this morning. Temperatures sit near 39 degrees at Philadelphia International Airport, and periods of rain will continue into midday. Some neighborhoods could pick up between a tenth and a quarter inch before conditions ease.

According to the National Weather Service in Mount Holly, rain remains likely through late morning with a 100% chance of measurable precipitation, while east winds stay near 5 mph. Clouds hold firm tonight, keeping lows near 37 degrees and setting up a quiet but gray start to the weekend.

Roads are wet, and visibility may dip in heavier showers.

Drivers along I-95, I-76, and the Schuylkill Expressway should allow extra braking distance through early afternoon. Plan for ponding on low-lying roads. With temperatures hovering in the upper 30s to near 40, any late-day clearing could lead to patchy slick spots if surfaces refreeze after sunset. This is prime flash-freeze season.

Saturday turns partly sunny with highs near 49 degrees. Enjoy the break.

By Sunday, colder air returns. Rain develops before midday, then mixes with and changes to snow late afternoon into Sunday night. A 30% chance of snow lingers into Monday. Even minor accumulation could create slushy stretches for the Monday commute if temperatures fall near freezing.

Looking ahead, midweek temperatures rebound into the 40s, and longer-range signals point to above-normal readings late next week — a hint of early spring warmth across Pennsylvania.

Five-Day Outlook for Philadelphia:

  • Saturday: Partly sunny, high 49.
  • Sunday: Rain, then rain/snow mix late, high 39.
  • Monday: Chance of snow, high 39.
  • Tuesday: Mostly sunny, high 37.
  • Wednesday: Mostly cloudy, high 43.
