A solar eclipse is an awesome spectacle, no matter the sky condition. Of course, a clear sky would create the most ideal weather, but what are the chances Mother Nature decides to hide the event behind the clouds?
While there's no promise of fair skies in the afternoon of August 21st, but past history, or weather climatology, does offer some clues. The National Oceanic and Atmospheric Administration, or NOAA, has compiled data to predict the likelihood of clouds or clear skies in the path of totality.
Some areas, especially the Oregon coast, are being listed as more likely to be cloudy during the eclipse while parts of the midwest have a lower chance of losing visibility. The historical data, of course, does not guarantee any weather conditions on August 21, 2017, so it's best to keep an eye on your local weather forecasts as the event gets closer.
