Philadelphia weather: Afternoon clouds, 25 mph gusts give way to frosty Monday morning

Blue skies and crisp temperatures in the 40s greet the Philadelphia region Sunday morning before afternoon atmospheric destabilization brings increasing gray stratocumulus clouds and wind gusts up to 25 mph. Daytime highs will reach the 50s before winds die down around sunset and skies clear overnight, sending temperatures into the 30s with patchy frost expected for Monday morning’s commute. After a lingering breeze on Monday, calmer winds and wall-to-wall sunshine take over for Tuesday, Wednesday and the rest of the seven-day forecast. Meanwhile, morning traffic is moving smoothly across the Pennsylvania Turnpike, I-76, Route 42 in New Jersey and I-95 in Delaware, though drivers should expect heavier volume near the South Philadelphia stadiums later today with both the 76ers and Flyers in action.
