Pennsylvania – Damp pavement glistens under early March skies across the Philadelphia region as mild air pushes north through the Mid-Atlantic. The morning begins quiet, but a fast warmup and a late-week rain-to-snow switch are now on the radar for commuters.
According to the National Weather Service in Philadelphia, temperatures will surge well above seasonal levels through midweek. Highs climb into the mid-70s by Wednesday afternoon, creating an early burst of spring warmth across southeastern Pennsylvania and nearby South Jersey.
Drivers across Philadelphia, Camden, Cherry Hill, and King of Prussia may encounter patchy fog early in the day. Visibility can briefly dip along river valleys and low-lying stretches near I-95, I-76, and the Schuylkill Expressway.
Sunshine returns by afternoon with temperatures rising near 70°F. The warm trend continues into midweek as southwest winds feed milder air into the region.
By Wednesday afternoon, Philadelphia could reach 76°F, nearly 20 degrees above normal for early March. Sidewalk cafés may fill quickly, and parks across the Delaware Valley should see heavy foot traffic.
Conditions begin shifting late Wednesday night.
Meteorologists are tracking a developing system that spreads rain into eastern Pennsylvania and New Jersey by Thursday afternoon. Roads could turn slick for the evening commute as steady showers move across the I-95 corridor.
Colder air may filter in Thursday night. Some models hint at rain mixing with wet snow before precipitation tapers early Friday. Temperatures could fall into the mid-30s, raising the chance for brief slushy spots on bridges and overpasses.
Travelers heading out for spring break later this week should keep an eye on changing road conditions.
Another update is expected as the system approaches. Are you seeing fog or sunshine where you are this morning?
