PHILADELPHIA (WPVI) — A weekend storm threat is looming for parts of the Philadelphia region.
The system could bring some snow to our area midday Sunday and last into Monday.
Models are still in dispute about how much of an impact this storm could have.
Here’s what we know so far:
Light precipitation is expected to begin Sunday morning across the Philadelphia region, with rain more likely early in the day before colder air moves in.
Light rain could develop by midmorning, around 10 or 11 a.m., especially in Philadelphia and areas to the south. While some light snow may mix in, temperatures are expected to be just warm enough at first to limit snowfall.
The high temperature Sunday is forecast to reach about 39 degrees, but temperatures are expected to fall late in the day. After about 4 p.m., colder air is expected to move into the region, allowing precipitation to change to snow across the area.
Drivers are urged to use caution and consider staying off the roads from late Sunday afternoon through Monday morning as snow continues Sunday night and into early Monday.
By 10 p.m. Sunday, snow is expected to be falling across much of the region, with light snow lingering into Monday morning before tapering off.
Forecast models continue to differ on how much snow will fall.
Most models suggest the storm system will track farther south, limiting impacts locally.
Under that scenario, snowfall totals of about 2 to 4 inches are possible in Philadelphia and the Lehigh Valley, with 3 to 8 inches possible closer to the coast.
One model, however, tracks the storm closer to the coast and suggests significantly heavier snowfall, potentially exceeding a foot in parts of the region.
However, that outcome is less likely at this time.
We will continue to monitor updated model data throughout the day.
