EL PASO, Texas -- The Borderland region has been seeing some foggy mornings this week, which are a bit unusual.
Several things need to come together to make it happen, and this week we’ve had the perfect set-up for fog-- cold air and moisture.
The most common form of fog, known as radiation fog, typically occurs on clear nights as the earth's surface cools moist air. If just enough light wind is present the chilled air can be gently stirred through a deeper layer.
When surface temperatures are below freezing, water droplets in a fog are super cooled, waiting to freeze on contact. These fog events can be dangerous and cause reduced visibility.
There are several other types of fog, click here for a complete list of those fog types from the National Weather Service.
