Erie, PA – A strong lake-effect system continues to sweep across northwest Pennsylvania, prompting a Lake Effect Snow Warning for Southern Erie and Crawford counties until 1 a.m. Saturday. The National Weather Service in Cleveland says snow bands coming off Lake Erie are still active, adding up to another inch of accumulation overnight and keeping roads slick well into the early morning hours.
Conditions Creating the Ongoing Snowfall
Cold air passing over the warmer waters of Lake Erie has maintained narrow but intense snow bands across the region. Forecasters report the heaviest snowfall will continue to develop over southern Erie County and stretch through northern and central Crawford County. Communities such as Meadville, Corry, and Titusville remain directly under these persistent bands.
The system has been slow to break apart, even as temperatures drop further and wind patterns shift. While snowfall rates are expected to ease gradually before sunrise, the National Weather Service warns that reduced visibility may occur without warning whenever bands intensify.
Impact on Thanksgiving Travel
The warning follows a busy Thanksgiving travel period, with many residents returning home late Friday. This timing increases the risk of traffic slowdowns and minor collisions on both major highways and rural routes across the region.
PennDOT is urging drivers to use caution, especially in areas prone to drifting snow. Officials note that even a small amount of fresh accumulation can create hazardous patches on untreated or lightly traveled roadways.
What Drivers Can Expect Overnight
Meteorologists say road conditions will remain slick until temperatures climb later on Saturday. The freezing air moving across the region enhances the chance of black ice in shaded areas, bridges, and overpasses. Motorists traveling early in the morning should allow extra time for their commutes.
PennDOT advises carrying basic emergency items such as water, snacks, gloves, and a flashlight. These supplies can be essential if vehicles become stranded or if sudden whiteout conditions slow traffic unexpectedly.

Broader Weather Pattern for Northwest Pennsylvania
This latest round of lake-effect activity marks another early taste of winter for northwest Pennsylvania. The region has already seen multiple systems this month, and forecasters expect lingering snow showers and chilly temperatures to continue through the end of November.
By Saturday afternoon, conditions should improve, though forecasters caution that additional lake-effect development is possible as colder air remains in place. Residents should stay alert for any new advisories issued by the National Weather Service.
Staying Safe Through Lake-Effect Events
Lake-effect snow presents unique challenges because it can intensify and shift quickly. Weather officials recommend that residents rely on verified forecast sources, keep phones charged, and avoid unnecessary travel during peak snowfall. Even brief bursts of snow can reduce visibility and create hazardous road surfaces.
Those planning weekend travel should monitor local forecasts and adjust plans as needed. Rural routes, especially those with limited lighting or steep inclines, may remain hazardous longer than major highways.
Conclusion
Northwest Pennsylvania is bracing for a few more hours of tricky conditions as lake-effect snow bands continue into early Saturday. With roads likely to remain slippery overnight, residents are encouraged to plan cautiously and stay informed as colder air ushers in the final days of November.
