Our comprehensive NEXT Weather forecast from CBS News offers detailed insights on the timing, intensity, and expected impact of this snow event across the Philadelphia metropolitan area.

When and How Much Snow Will Philadelphia Receive This Week?
Snow is forecasted to commence late Tuesday night, gradually intensifying through the early hours of Wednesday. Temperatures are expected to remain just below freezing, which will likely cause hazardous road conditions as precipitation transitions from rain to snow. Motorists should anticipate challenging travel during Wednesday’s morning rush hour, especially on major highways encircling the city, where slick surfaces and diminished visibility will be prevalent.
Snowfall will continue throughout Wednesday, with accumulations predicted between 2 and 4 inches across most neighborhoods. Winds gusting from 15 to 25 mph will exacerbate conditions by causing blowing snow and drifts, particularly in exposed areas. By Wednesday evening, the snow will gradually subside, leaving behind cold, cloudy skies into Thursday morning.
- Onset: Tuesday at 10 PM
- Peak Snowfall: Wednesday from 6 AM to 12 PM
- Snow Depth: 2 to 4 inches expected
- Wind Gusts: 15 to 25 mph
| Day | Time Frame | Weather Conditions | Temperature |
|---|---|---|---|
| Tuesday | 10 PM–12 AM | Light Snow Begins | 31°F |
| Wednesday | 6 AM–12 PM | Heavy Snow with Blowing Snow | 29°F |
| Wednesday | 12 PM–6 PM | Moderate Snowfall | 28°F |
| Wednesday | 6 PM–12 AM | Snow Diminishes | 27°F |
Atmospheric Dynamics Behind This Week’s Snowfall
The anticipated snowstorm over Philadelphia results from a convergence of meteorological factors, including a progressing low-pressure system coupled with a surge of frigid air descending from the north. A pronounced dip in the jet stream is channeling moisture from the Atlantic Ocean, while a steadfast cold front is driving temperatures below freezing. These elements combine to create optimal conditions for snow, particularly during overnight hours when surface temperatures reach their lowest.
Several critical components influence the snowfall’s distribution and intensity:
- Humidity Levels: Elevated moisture content across southeastern Pennsylvania enhances snow formation.
- Temperature Range: Near-surface air temperatures between 28°F and 32°F favor pure snow over mixed precipitation.
- Wind Direction and Speed: Increasing northerly winds contribute to snowdrifts and uneven accumulation.
| Weather Parameter | Effect on Snowfall |
|---|---|
| Low-Pressure Path | Tracks east of Pennsylvania, boosting snowfall totals |
| Temperature Decline | Sharp drop after sunset solidifies snow formation |
| Wind Gusts | Up to 25 mph, increasing potential for snowdrifts |
Essential Winter Safety Measures and Preparation Tips for Philadelphia Residents
With the snowstorm imminent, it’s vital for Philadelphia residents to take proactive steps to safeguard themselves and their families. Gathering essential supplies such as non-perishable foods, bottled water, batteries, and reliable flashlights is highly recommended. Ensure you have a functional snow shovel and adequate de-icing materials like salt or sand to maintain safe walkways and driveways. Charging mobile devices ahead of time and having warm clothing layers readily available is crucial, as power outages can occur during heavy snowfall. Additionally, checking in on elderly neighbors or those with limited mobility can provide critical support during adverse conditions.
Travel plans should be reconsidered; if travel is unavoidable, inform someone of your route and expected arrival time. Vehicles should be equipped with winter emergency kits containing blankets, first aid supplies, and extra windshield washer fluid. Coordinating snow removal responsibilities among household members can expedite clearing efforts and reduce the risk of accidents. Below is a checklist to help prioritize your preparations:
- Verify heating systems are operational and serviced.
- Keep emergency contact numbers accessible.
- Update your winter emergency plan regularly.
- Stay tuned to local weather alerts and advisories.
| Preparation Item | Recommended Action |
|---|---|
| Emergency Supplies | Stockpile enough for at least 72 hours |
| Vehicle Preparedness | Include winter emergency kit and tire chains |
| Home Safety | Clear gutters and test smoke/carbon monoxide detectors |
| Communication Plan | Establish regular check-in routines |
How Snowfall Will Affect Philadelphia’s Transportation and Public Services
As Philadelphia prepares for this winter weather event, transportation networks are bracing for potential interruptions. Snow and icy conditions often cause delays or cancellations in public transit, especially impacting bus routes in suburban areas and regional rail lines with exposed tracks. Ride-share services may experience longer wait times, and airport operations could face delays due to aircraft de-icing and limited visibility. Commuters are encouraged to plan extra travel time and verify service updates before departure.
Community services will also be affected. Emergency responders prioritize clearing main roads to maintain access, which may delay response times in residential neighborhoods. Public facilities such as libraries and community centers might modify hours or close temporarily to ensure safety. Residents should monitor official communications for the latest information on service availability.
- Public Transit: Anticipate schedule changes and delays.
- Road Maintenance: Priority given to major arteries for snow removal.
- Emergency Response: Focus on cleared routes for timely access.
- Community Services: Possible operational adjustments or closures.
| Service | Level of Impact | Resident Recommendations |
|---|---|---|
| SEPTA Bus Lines | High | Check live updates before traveling |
| Regional Rail | Moderate | Expect delays during peak periods |
| Emergency Medical & Fire Services | High | Keep driveways and access points clear |
| Libraries & Community Centers | Low | Confirm hours prior to visiting |
