A wave of winter weather is expected to impact the Philadelphia region overnight on December 22, bringing light snow that could lead to slippery conditions on the morning of December 23. The National Weather Service has increased its confidence in the forecast, predicting a 50% to 70% chance of light snowfall during the late hours of December 22, particularly north of the Philadelphia metropolitan area, with minimal accumulation of less than an inch anticipated.
In areas further south, including the Delmarva region and parts of lower New Castle, Kent, and Sussex counties, there is a forecasted 30% to 50% likelihood of a mix of rain and snow. While the predicted totals are small, meteorologists caution that untreated roads may pose a hazard for commuters on the morning of December 23. Fortunately, temperatures are expected to rise above freezing later that day, which should improve travel conditions.
Temperatures on December 21 will align more closely with seasonal expectations, being approximately five degrees warmer than the previous day. The forecast indicates that colder air will move in overnight, resulting in lows dipping into the low to mid-20s.
As the winter season approaches, residents are urged to prepare their vehicles for snow and ice. Community groups and service providers are encouraged to share their news and updates, fostering a collaborative environment to keep residents informed.
