Should you get the telescope out tonight? How long do you have before clouds roll in? What will the seeing be like?
detailed cloud forecast
- 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.
