Frigid temperatures and strong winds are set to envelop the region this Saturday, with wind chill values plummeting near zero. Expect snow showers primarily north and west of Philadelphia in the morning, while other areas may experience a mix of rain and snow. Looking towards Sunday, another storm system could potentially affect South Jersey and Delaware, although it is currently anticipated to remain offshore.
Forecasters predict that Saturday will deliver bitter cold, accompanied by a chance for snow showers, particularly in areas north and west of Philadelphia. Starting temperatures in the city will be around 25 degrees, but wind chills could range in the single digits and teens, fueled by gusts reaching up to 27 miles per hour in the morning. Highs throughout the district will struggle to breach the 30s, with Allentown barely expected to hit the freezing mark.
Initially, snow showers will blanket Philadelphia by early afternoon before transitioning to primarily rain. Meteorologist Orr noted, “If we do not cool below that, we’ll have a mix of rain and snow, and we can see South Jersey warm enough for rain.” The best potential for snow accumulation lies to the north and west of the city, where colder air remains. Current snowfall predictions are modest, with the GFS model estimating close to an inch and the HRR model suggesting about a third of an inch, although less than an inch is projected for Philadelphia itself.
As of now, the Philadelphia area is experiencing a “snow drought,” having recorded only 4.8 inches this winter, predominantly from a single event on December 14. This weekend is set to begin with harsh wind chills and potential snow, especially impacting the Poconos and surrounding regions.
Regarding Sunday’s anticipated storm, while the primary effects are expected to remain coastal, there is a possibility it could extend into the interior parts of New Jersey and Delaware should conditions alter. Current models, including the GFS and European forecasts, suggest the storm will stay clear of the area, but meteorologists will provide updates should the storm’s trajectory change.
Looking ahead to Martin Luther King Jr. Day on Monday, January 19, a high of 36 degrees is expected. However, the coldest morning will likely occur on Tuesday, January 20, with temperatures dropping into the teens and wind chills forecasted in the single digits. As the region braces for this cold snap, further blasts of arctic air may follow after a brief respite in conditions. Meteorologist Orr advises residents to prepare adequately for the impending chill.
