Philadelphia braces for a sharp chill after mild stretch

A welcome respite from winter’s bite is ending in the Philadelphia region. After a pleasant weekend and early week, residents should prepare for a significant temperature drop arriving Tuesday, potentially impacting early-season vegetation.

Clear skies give way to a deep freeze

The front that brought the mild weather has cleared, leaving behind a period of clear skies overnight and sunny conditions for Monday. Temperatures will hover around a comfortable 60 degrees during the day, a welcome return to seasonal norms. However, don't let that warmth lull you into complacency. A northwest wind, picking up to 10-20 mph with occasional gusts, will add a breezy feel to the afternoon.

But the pleasant conditions are fleeting. Tuesday afternoon marks a dramatic shift, with temperatures plummeting into the low 50s. The overnight low Tuesday night is forecast to dip into the upper 20s and low 30s – a chilling reminder of winter's lingering grip. Gardeners and homeowners should be aware that these freezing temperatures could cause damage to any early-season plants that have begun to emerge. Protect vulnerable seedlings accordingly.

The good news? This arctic intrusion is brief. A warming trend is on the horizon, with temperatures steadily climbing back into the 60s by Thursday, reaching the 70s by Friday and Saturday. Sunday will bring partly cloudy skies and a high near 73 degrees, offering a final taste of spring-like warmth before an uncertain future.

Here's a look at the 7-day forecast:

• Monday: Sunny and cooler. High 61, low 42.
• Tuesday: Sunny and cool. High 52, low 43.
• Wednesday: Chilly start. High 54, low 31.
