This often causes freezing fog on mountaintops, where the cloud ceiling would not otherwise be low enough. Valley fog forms in mountain valleys, often during winter. It is essentially a radiation fog confined by local topography and can last for several days in calm conditions. In California's Central Valley, valley fog is often referred to as ...
Tule fog is a radiation fog, which condenses when there is a high relative humidity (typically after a heavy rain), calm winds, and rapid cooling during the night. The nights are longer in the winter months, which allows an extended period of ground cooling, and thereby a pronounced temperature inversion at a low altitude.
It is not generally true that fog season in a given area is during autumn or winter (the cooler months); for example, the Japanese coast of the Pacific Ocean has a dense fog season from May to August. The June Gloom, a cloudy and foggy phenomena, experienced in the southern coast of California occurs in late spring and early summer (May and June).
Whether you're heading home after the holidays or heading on your first vacation of the new year, the busy holiday travel period continues, and weather may be a factor. For some, snow, rain ...
A dense fog blanketed portions of the Kansas City area Wednesday and continued into Thursday. The National Weather Service’s local office breaks down where the fog comes from and why it’s here ...
With sufficient humidity in the cooler layer, fog is typically present below the inversion cap. An inversion is also produced whenever radiation from the surface of the earth exceeds the amount of radiation received from the sun, which commonly occurs at night, or during the winter when the sun is very low in the sky.
It is often seen on trees atop mountains and ridges in winter, when low-hanging clouds cause freezing fog. This fog freezes to the windward (wind-facing) side of tree branches, buildings, or any other solid objects, usually with high wind velocities and air temperatures between −2 and −8 °C (28 and 18 °F).
Thursday's weather will feature an Arctic blast for the Midwest and Northeast and still more lake-effect snow for the Great Lakes. Cold air associated with a high-pressure area will move over the ...
