The National Weather Service has issued a Freeze Watch for the Philadelphia area, warning that overnight lows are expected to fall into the 20s to low 30s, cold enough to damage sensitive plants and early crops. Daytime highs on Tuesday will reach the low 50s, but clear skies and gusty winds overnight will allow temperatures to drop rapidly, increasing the likelihood of widespread frost by daybreak on Wednesday.

Why it matters

Sudden drops in temperature can pose a significant threat to early spring vegetation, crops, and outdoor plumbing in the Philadelphia region. Residents will need to take steps to protect their property from the impending freeze conditions.

The details

According to the National Weather Service in Mount Holly, the Freeze Watch is in effect overnight Tuesday into early Wednesday for areas where the growing season has begun, including Philadelphia, Wilmington, Trenton, and much of South Jersey. Daytime highs on Tuesday will reach around 53°F in Philadelphia and the mid-50s along the Jersey Shore, but gusty northwest winds of 15 to 20 mph will make it feel colder, especially on exposed roadways. Clear skies Tuesday night will allow temperatures to drop rapidly, increasing the likelihood of widespread frost by daybreak on Wednesday.
