Meteorologists and weather enthusiasts are interested not only in the incredible spectacle, but also in the small ways this eclipse will affect such things as temperatures and winds. 

(INTERACTIVE: Map With Clouds, Rain)

We have a series of maps, webcams and graphs below through which you may be able to detect the effect of the eclipse on the weather.

Temperatures

You should expect a drop of 5 to 15 degrees in the path of totality under clear skies.

If skies are clear, you may notice some temperature differences between locations on a regional scale during the eclipse that you wouldn't expect.

Satellite Images

This one is pretty straight-forward. You should notice a pronounced darkening in visible satellite images as the moon's shadow is cast during the eclipse. You can see examples of this from a 2016 eclipse over the Pacific Ocean and a 1984 annular eclipse in the Southeast U.S.

Weather Underground Data Graphs

Again, thanks to our friends at Weather Underground, we have several graphs below which illustrate the time series of temperature, surface pressure and winds on August 21. 

A study from the University of Reading found winds diminished on average by 2 mph and subtly changed direction during a 2015 partial eclipse in the United Kingdom, a so-called eclipse wind.
