Black Ice After the Storm: Why Roads Are Still Dangerous Even on Sunny Days

Even with sunshine returning and temperatures climbing above freezing, dangerous road conditions can persist across Rowan, Davie, and Davidson Counties following a winter storm. The reason: black ice.

Black ice is especially common in the days immediately after snow and ice events, and it often catches drivers off guard because roads may look dry while still being slick.

Why Black Ice Is Still a Problem

After a snowstorm, melting begins once temperatures rise above freezing. During the day, snow and ice melt on road surfaces, parking lots, sidewalks, and driveways. Once the sun sets or temperatures drop back below freezing, that meltwater refreezes, forming a thin, nearly invisible layer of ice.

This process can repeat for several days after a storm, especially during periods of cold nights and sunny afternoons.

The Most Dangerous Locations

Black ice does not form evenly. Some areas are much more prone to refreezing than others, including:

• Bridges and overpasses, which cool faster than roads over land

• Shaded roadways that receive little direct sunlight

• North-facing slopes

• Untreated secondary roads

• Parking lots, sidewalks, and driveways

Even when main roads improve, shaded and elevated areas can remain icy all day.

Why Sunny Weather Can Be Misleading

Sunny skies often give a false sense of security. While sunlight helps melt snow and ice, it also increases runoff during the day. That moisture can refreeze quickly once temperatures drop again, especially after sunset.

In areas that remain shaded throughout the day, melting may be limited, allowing ice to persist much longer than expected.

What This Means for Drivers and Pedestrians

Travelers across Rowan, Davie, and Davidson Counties should continue using caution, especially during the morning and evening hours.

Drivers should:

• Slow down and increase following distance

• Be extra cautious on bridges and overpasses

• Watch for slick spots on less-traveled roads

Pedestrians should:

• Use caution on sidewalks, steps, and parking lots

• Be aware that icy patches may not be visible

The Bottom Line

Even after the snow stops and skies clear, black ice can remain a serious hazard. Conditions can vary significantly from one road to the next, and from one neighborhood to another.

Continue using caution until overnight temperatures consistently remain above freezing and all surfaces have had time to fully dry.
