took in the longer chart!

Spotted a note on Cloudy Nights, entitled "Even longer clear sky chart forecasts." From Attilla Danko no less.

For sponsored charts, he now displays an additional 5 days of cloud forecasts.

new extended display from Clear Sky Charts

There are two extended cloud forecasts; the CMC cloud forecast and the ECMWF cloud forecast. The extended data covers an extra 5 or 6 days into the future for a total of an 8 or 9 day forecast. 

Of course, cloud forecasts far out into the future are less accurate.

The extended CMC cloud forecast is available every 3 hours. The extended ECMWF cloud forecast is available every 6 hours. 

The extended forecasts on sponsorsed clear sky charts in a separate panel at the bottom of the chart image.
