There are quite a few different types of fog, well, different names for fog anyway. Basically, fog is a cloud that is in contact with the earth, but how it forms can be because of a variety of reasons. Radiation fog forms because of the cooling of the land and usually happens in the fall. Advection fog occurs when moist air passes over a cool surface. This happens a lot when warm fronts pass over areas of snow. Steam fog is formed when cold air passes over warm water; this happens a lot around the Great Lakes and is closely related to Lake Effect Snow. Precipitation or frontal fog happens when rain falls into a very dry air mass and the rain evaporates and saturates the air mass and then fog can form. Upslope fog occurs when wind blows air up a slope, like a mountain slope, and this condenses the air causing fog to form. Valley fog happens when cold air settles into a valley and there is warm air up above it. This is also called an inversion and happens quite often in the mountains. Ice fog is a type of fog that occurs when the temperature is very, very cold and water droplets are frozen in midair. It’s usually fairly tough to know when you’re in the fog what type it is so feel free to call any fog you’re in “pea soup.”

Forecast discussion for the week ahead:
After an unsettled weather pattern gives us a chance at some much needed precipitation, we’ll dry out for the second half of the weekend and into next week. It will certainly be cooler heading through the weekend, but high pressure will build back in, bringing back some sunshine and warmer temperatures.
