Dense Fog & Severe Storms: Aaron White’s Forecast

Dense fog is impacting visibility across much of Ohio this morning, with meteorologist Aaron White forecasting conditions where visibility is less than a quarter of a mile in some areas. The National Weather Service has issued Dense Fog Advisories for most of the state, warning of hazardous commuting conditions.

The fog, which began developing overnight, is expected to persist through the morning hours, potentially creating icy conditions on bridges and overpasses as temperatures hover near freezing. The National Weather Service advises drivers to slow down, use headlights, and increase following distances. Counties in the Toledo area are currently excluded from the advisory, but the remainder of the state is affected.

While the fog is the immediate concern, Aaron White is as well tracking the potential for strong to severe thunderstorms later this evening. According to a Facebook post, the risk of severe weather is concentrated in specific areas, with dark green and yellow zones indicating the highest probability. Non-severe storms are possible in lighter green areas, but widespread severe weather is not currently anticipated.

The National Weather Service defines a dense fog advisory as being issued when visibility is reduced to a quarter mile or less. Freezing fog, a related phenomenon, occurs when temperatures are at or below freezing, causing fog droplets to freeze on surfaces and create slick roadways. Fog typically forms when warm, moist air passes over colder surfaces, causing condensation.
