Clouds and temperatures near 50°F greeted Philadelphia on Tuesday morning, but the real drama shows up late tonight into Wednesday. A Freeze Warning is set to kick in for parts of the metro from midnight through about 9 a.m. Wednesday, and brisk northwest winds this afternoon will make it feel cooler than the numbers suggest. Forecasters are also flagging an elevated fire risk this afternoon as a dry, windy airmass settles in. After morning clouds, expect plenty of sun and highs around 50 to 55°F, as reported by the National Weather Service.
Freeze Warning And Frost Threat
A Freeze Warning covers parts of the Philadelphia area from midnight tonight through about 9 a.m. Wednesday, with lows expected in the mid 20s to around 30°F. That is cold enough to kill tender spring growth and potentially damage unprotected outdoor plumbing. If you have potted plants, bring them inside and cover vulnerable vegetation, and leave a slow drip on exposed faucets if you are concerned about pipes. The advisory comes from National Weather Service Mount Holly, which has also issued a Freeze Watch for Wednesday night into Thursday morning for the coolest inland spots.
Afternoon Winds Pick Up
Sun returns for the afternoon with highs near 53°F and northwest winds of 5 to 20 mph, with gusts up to 35 mph in exposed locations. Those gusts will help temperatures drop quickly this evening. The mix of dry air and gusty winds brings an elevated fire spread risk, and officials are urging residents to skip outdoor burning and use extra caution with yard debris. The earlier shift toward dry, windy conditions was detailed in sun soaked Monday, fire fears Tuesday.
Boaters And Commuters
Small Craft Advisories begin at 9 a.m. for the Delaware Bay and 11 a.m. for Atlantic coastal waters, with seas of 3 to 5 feet and northwesterly gusts making for choppy conditions for small vessels. On land, the wind will push a chill across riverside areas and make biking or walking feel colder than the thermometer, so secure garbage cans and any loose outdoor furniture. Tonight, skies clear while temperatures fall into the 20s to low 30s across much of the metro, setting up a frosty Wednesday morning in many neighborhoods.
Practical steps: bring potted plants indoors, cover garden beds and young shrubs, wrap exposed pipes or let faucets trickle overnight, and hold off on any planned brush burning. Keep an eye on local alerts and changing conditions.
