DISCLAIMER: This weather data is based from past forecast records, not from sky observations. So it's possible that it is not an accurate indication of weather for the eclipse. If you miss seeing the eclipse because you took a climate/history page for a clear sky chart, or the weather data on this page, too literally, your only recourse is to complain to me in email.
