You may notice some resemblance between clouds associated with a real cyclone and those indicated in the previous drawing. Each is helpful for specific purposes, but VIS images tend to most clearly depict cloudiness . High resolution is very helpful for images, some meteorological satellites' being 1 km, but most available ones 4 or 8 km. Sounding data is very useful, but balloon soundings quickly become old, as our atmosphere is constantly changing. Satellite soundings can sometimes be used though, providing current atmospheric profiles.
Many people are familiar with morning fog, especially after rain occurred the previous night.
Cloudiness tends to be most abundant during late afternoon and early evening, and least so during late morning, solar energy often heating clouds, causing them to dissipate. A surface Low developed south of the Ohio Valley states, developing northward and even slightly westward.
