The winter of 2025-26 is set to deliver the first measurable snowfall to Philadelphia this weekend. Forecasters predict this snowfall could be significant, potentially reaching amounts not seen in the past two winters. The National Weather Service announced a 95% likelihood of at least one inch of snow accumulating in the area.

Snowfall Predictions for Philadelphia

The latest predictions indicate that most regions may see around three inches of snow. Senior meteorologist Matt Benz mentioned that totals could be “a little bit” higher, especially in areas south and east of the city. There is also a 40% chance that parts of the immediate Philadelphia area could receive up to four inches of snow, surpassing the 3.1 inches recorded on February 11-12.

Timeline and Conditions

• Snow or a mix of rain and snow is expected to commence late Saturday night.
• Temperatures are forecasted to drop below freezing, transitioning to all snow.
• Early Sunday may witness snowfall rates of one inch per hour.

Forecasters believe there is potential for concentrated snowfall of four to five inches along the I-95 corridor, particularly to the south and east. There is also a 20% to 30% chance that some areas may exceed five inches.

Snow Longevity and Historical Context

This snow is expected to persist at least until midweek. The temperatures during this period are likely to hover around freezing or lower, with minimal sunlight to hasten melting. Last February’s snowfall rapidly disappeared once temperatures rose to near 50 degrees.

This approach to winter marks a stark contrast to last season, where snow totals in Philadelphia remained well below normal. Over the last four winters, the official snowfall recorded at Philadelphia International Airport has been less than half the average, which is 23.2 inches per season.

Comparative Snow Totals

In comparison, Richmond, Virginia, has recorded six inches of snow so far this winter. The city measures a total of 22.8 inches since last December, almost triple the amount accumulated in Philadelphia.

Future Weather Outlook

This meteorological winter began on December 1 and is off to a wintry start, with average temperatures more than six degrees below normal. However, it has not been particularly wet, as anticipated precipitation this weekend is not expected to exceed a half-inch of liquid.

The NOAA’s Climate Prediction Center has indicated that it is uncertain whether precipitation levels will be above or below normal through December 26. Still, there is a strong prediction for warming trends on the horizon.

While snowfall on Christmas is rare in Philadelphia and along the I-95 corridor, residents can look forward to a white Sunday, marking a notable event in this winter season.
