  • The clear dark sky chart summarizes cloudcover and transparancy for the next up to 20 hours.  Lighter colors are bad, darker are good for observing.
  • National Weather Service graphs cloudcover, precip, wind, and other predictions.  These are the most specific forecasts, targeted to a 8 km2 area
  • WeatherSpark presents that same data in a dashboard format that some find easier to read and scroll ahead for forecasted conditions. Slightly less specific, targeted at city level.
