Melting snow and light winds led to dense fog across parts of Northeast Ohio on Monday, with similar visibility issues expected again on Tuesday. The combination of increased moisture from melting snow and light winds created ideal conditions for fog development, reducing visibility in some areas. Forecasters also noted that the rapid snowmelt is releasing fine particulate matter into the air, impacting air quality in the region.

Why it matters

Fog can create dangerous driving conditions, reducing visibility and increasing the risk of accidents. Additionally, the release of fine particulate matter from melting snow can negatively impact air quality, posing health risks for sensitive groups like children, older adults, and those with heart or lung conditions.

The details

As temperatures climbed and snow began melting across Northeast Ohio, moisture was released back into the air. With only light winds in place, that moisture lingered near the surface, creating ideal conditions for fog development. The fog was not uniform, with some areas seeing denser fog than others. Forecasters expect similar fog conditions again overnight into Tuesday morning. Drivers encountering fog are advised to use low-beam headlights, reduce speed, and allow extra distance between vehicles.

  • On Monday morning, dense fog blanketed parts of Northeast Ohio.
  • Forecasters expect similar fog conditions again overnight into Tuesday morning.

What they’re saying

“Light wind, a lot of moisture in the air, and snowpack — and sometimes you get a little warmer air moving over top of that snowpack. The light wind doesn't move things around too much, so it helps allow the fog to develop.”

What’s next

Forecasters expect similar fog conditions again overnight into Tuesday morning, and drivers should be prepared for reduced visibility.

The takeaway

This case highlights the impact of melting snow on both fog and air quality in Northeast Ohio. As temperatures rise, the release of moisture and fine particulate matter can create hazardous conditions for residents, underscoring the importance of weather monitoring and public awareness.
