Pennsylvania Braces for Late-Night Heavy Snow Squalls With New Timing Update
Pennsylvania – A new round of forecast data shows that Pennsylvania will face a dangerous late-night snow squall, arriving later than originally expected and posing serious travel risks for anyone on the road heading into the early hours of New Year’s Eve celebrations. Weather experts warn that this squall will be brief but intense, capable of dropping visibility to near zero and producing hazardous conditions within minutes.
Squall Expected to Arrive Later Than Previously Forecast
The newest model guidance shifts the timing of the snow squall into late tonight and early Thursday morning, impacting areas across central and western Pennsylvania.
Forecasters now expect a 25–45 minute burst of heavy snow, accompanied by:
- Wind gusts of 35–45 mph
- A rapid 1–2 inches of snowfall
- Instant slick spots from ice formation
- Visibility dropping to near 0 miles
Officials urge drivers to plan ahead, especially those traveling late to attend midnight New Year’s events.
Severe Travel Hazards Expected on Highways
The combination of flash snow, strong winds, and fresh treatment melt refreezing on roadways will create rapidly deteriorating conditions, particularly on interstates.
Highways are at heightened risk for multi-vehicle pileups, which are a known danger during snow squalls because:
- Drivers cannot see brake lights ahead
- Roads ice over in minutes
- Heavy snow continues even as vehicles slow down
- Reaction times decrease as visibility collapses
Authorities emphasize that snow squalls are not typical snowfall events—they behave more like brief, fast-moving winter thunderstorms with extreme travel impacts.
What To Do If a Snow Squall Hits While Driving
If a snow squall arrives while you are traveling, experts strongly recommend:
- Immediately exiting the highway at the nearest safe location
- Avoiding hard braking, which can trigger chain-reaction crashes
- Reducing speed and increasing following distance
- Waiting for the squall to pass, which typically takes less than an hour
If caught in a pileup, do NOT exit your vehicle. Standing on the roadway during low visibility can be fatal as additional vehicles lose control approaching the scene.
Final Advisory Ahead of New Year’s Eve
With thousands expected to travel for New Year’s Eve events, tonight’s conditions demand advance planning and extreme caution. The late-night timing means many drivers may be on the road just as the squall arrives, increasing the risk of serious accidents.
