The air feels sharp and metallic this morning as winter tightens its grip across eastern Pennsylvania. Breath hangs visible, sidewalks crunch lightly, and parked cars wear a thin crust of frost as the day begins.
According to the National Weather Service, Philadelphia starts the day near 21°F, with wind chills dipping into the single digits. Northwest winds add bite, and untreated surfaces may stay slick early. A slight snow shower chance develops later today, mainly after midday, as clouds increase and temperatures struggle to rise toward 29°F. Any flakes would be light but could briefly coat colder pavement.
Travelers should slow down on bridges and shaded roads, where cold air lingers longest. Dress in layers and keep gloves handy, especially during early errands or school drop-offs. Conditions may change quickly where sun and clouds alternate.
By Tuesday, calmer weather returns. Sunshine dominates, but highs stay near 32°F, keeping winter firmly in place. Wednesday brings a noticeable shift, with brighter skies and temperatures climbing into the low 40s. That warm-up signals a transition rather than an end to winter risks.
Later Thursday, clouds thicken and milder air pushes highs into the low 50s. Rain becomes likely Thursday night, with an 80% chance. With cold ground still in place, residents should watch for slick spots if temperatures cool afterward. Meteorologists note this pattern as an early-season setup where flash freezing can follow wet roads.
