Philadelphia, February 20, 2026
The Philadelphia region is preparing for a potential winter storm this weekend, with precipitation expected to begin on Sunday and continue into Monday. Meteorologists predict two main scenarios: a weaker storm resulting in light, wet snow or a stronger storm that could lead to significant snowfall and high winds. Current weather conditions are marked by rain, and a Winter Weather Advisory is in effect for certain counties. As the low-pressure system develops, uncertainty remains regarding the storm’s trajectory and impact.
Philadelphia Braces for Weekend Snow, Impact Remains Uncertain
Philadelphia, PA – The Philadelphia region is anticipating a potential winter storm this weekend, with snow forecast to begin on Sunday and continue into Monday. The exact impact of the developing low-pressure system remains highly uncertain, with meteorologists describing it as a “boom or bust” scenario.
Forecast Details and Scenarios
Precipitation is expected to arrive on Sunday, transitioning from a rain/snow mix during the day to accumulating snow by evening. Current models present two main possibilities for the Delaware Valley. The most probable outcome, with a 70% chance, suggests a weaker storm that passes farther offshore, leading to light, wet snow starting midday Sunday and continuing into Monday. This scenario could still produce localized bands of heavier snowfall.
A less likely but more severe scenario, with an estimated 30% chance, indicates a stronger storm tracking closer to the coast. This could result in significant snowfall, potentially exceeding a foot in some areas, accompanied by wind gusts up to 50 mph, which might create blizzard-like conditions. Forecast models from MSN Weather currently suggest up to 1.02 inches of snowfall is possible for Sunday night.
Current and Upcoming Conditions
Friday is experiencing rain in the Philadelphia area, which could lead to disruptive road spray and ponding. A Winter Weather Advisory is in effect until Friday noon for Carbon and Monroe Counties in Pennsylvania, and Sussex County, New Jersey, where light freezing rain and snow/sleet are anticipated. Saturday is expected to be mild and dry with partly sunny skies and highs around 50°F, providing a brief calm before the potential storm.
Ongoing Monitoring
The low-pressure system is still developing over the West Coast, and meteorologists are closely monitoring its trajectory and strength. Details regarding the weekend storm are expected to become clearer by Friday night as new model data emerges. The wide disagreement among current forecast models contributes to the high level of uncertainty concerning snow accumulation.
