Philadelphia Snowfall Predictions: How the Storm’s Path Could Affect Totals
The Philadelphia region is bracing for a significant winter storm this weekend, with temperature forecasts indicating some of the coldest air of the season. From Friday through Monday, the region will experience highs in the teens and low 20s, and lows reaching single digits.
Philadelphia Snowfall Predictions: Understanding the Storm’s Path
As meteorologists predict potential snow totals, several key factors will influence how much accumulation the city will see. The expected snow-to-water ratio for this storm is notably high at 20:1. This means that snow produced from each inch of water will amount to approximately 20 inches of snow.
Potential Snow Accumulations
If we consider water content, the forecast indicates:
- Half an inch of water could yield 10 inches of snow.
- A quarter inch of water may result in 5 inches of snow.
- Three-quarters of an inch of water could produce 15 inches of snow.
Storm Track and Uncertainty
The most significant variable in snowfall prediction remains the storm’s track. Current models suggest the storm could originate in the southern plains, progressing northeast through the Carolinas into the Atlantic. Philadelphia might either be near the storm’s northern edge or closer to its center, significantly affecting potential snowfall.
Projected snow totals vary widely based on these tracks. For instance:
- If positioned on the northern edge, snow accumulations could be minimal, possibly just a coating to 3 inches.
- If closer to the storm center, totals might reach between 6 to 12 inches or more.
Model Predictions
| Model | Snow Accumulation | Coverage Area |
|---|---|---|
| European (ECMWF) | Heaviest | From Virginia through Philadelphia to New York |
| American (GFS) | Lower amounts | From Tennessee through Delaware |
| National Blend of Models (NBM) | Medium amounts | From Virginia through northern Delaware |
Timing of the Winter Storm
The storm is expected to develop later this week, impacting the area from late Saturday through Monday evening. Residents should prepare for heavy snowfall and possible school delays or closures on January 26.
As conditions evolve, staying updated with local weather reports will be crucial. Residents are encouraged to be ready with snow removal tools and ice melt, as this winter storm may deliver the heaviest snow the season has seen to date.
