Philadelphia, Pennsylvania – Drivers and commuters across the Philadelphia region should prepare for a challenging start to Friday as heavy rain, thunderstorms, and strong winds move through during the early morning hours. Forecasters have issued a NEXT Weather Alert due to the potential for ponding, reduced visibility, and hazardous travel conditions during peak commute times.
Storm System Targets Early Morning Hours
The most significant impacts are expected between 3 a.m. and 7 a.m., when steady, heavy rainfall moves across southeastern Pennsylvania, South Jersey, and Delaware. Some locations could receive one inch of rain or more, enough to slow traffic and cause localized flooding in poor drainage areas.
After a brief lull mid-morning, a second round of wind-driven downpours and thunderstorms may sweep through between 9 a.m. and 11 a.m., adding another layer of difficulty for commuters already on the roads.
Flooding Risk and Snowmelt Concerns
While the region has experienced relatively dry conditions recently, the incoming rain will melt lingering snow, increasing runoff into streets and storm drains. Officials say rivers and streams should remain within their banks, but urban flooding remains possible where drainage systems become overwhelmed.
Drivers are urged to slow down, allow extra travel time, and never drive through flooded roadways, even if the water appears shallow.
Wind Advisory and Power Outage Risk
As rain tapers off Friday afternoon, conditions will quickly shift. Strong northwest winds are expected to develop, with gusts reaching up to 50 mph in some areas. A Wind Advisory is in effect, and residents are encouraged to secure loose outdoor items.
Homeowners should:
- Bring trash cans inside promptly
- Avoid inflating holiday decorations
- Fully charge phones and backup batteries
- Be prepared for isolated power outages
Temperature Swing Brings Sudden Cold
One of the most dramatic changes will be the temperature drop. Morning readings will start near 60 degrees, but colder air rushing in behind the storm will cause temperatures to plummet rapidly by evening.
By Friday night, wind chills may fall into the low teens or even single digits, creating a sharp contrast from the mild, rainy start to the day. Heavy winter coats will be necessary by nightfall.
What to Wear: Layers Are Key
Forecasters recommend dressing in layers if you plan to be out all day. A t-shirt or light sweatshirt may suffice early in the morning, but winter gear will be needed later, especially as winds strengthen and temperatures fall.
Umbrellas will be essential during the morning hours, though strong winds could make them difficult to use during heavier downpours.
Weekend Outlook Brings Improvement
Once the storm exits, the weekend looks colder but calmer. Saturday will feel brisk with sunshine returning, while Sunday brings a noticeable warm-up.
- Saturday: Chilly and dry, with highs near 40 degrees
- Sunday: Milder and pleasant, highs around 51 degrees
Early Next Week and Holiday Travel Forecast
Temperatures will fluctuate early next week, with another cold snap expected Monday. Overall, travel conditions look mostly favorable heading into the Christmas holiday period.
There is a low chance of rain or snow showers Tuesday, and forecasters are monitoring a possible light wintry mix Christmas morning, though nothing appears disruptive at this time.
