Clear Outside

Clear Outside compresses a week's observing prospects into a grid that can be scanned in seconds. Every hour carries separate low, middle, high and total cloud values, with bands for astronomical darkness and the Moon. Rain, wind, temperature, humidity and dew point help decide whether optics are likely to fog or a lightweight setup will shake. Sunrise, sunset and ISS passes share the same timeline, so a short clear interval is easier to recognize than it would be across several general weather pages.

The design favours quick decisions over meteorological diagnosis. It does not provide the same spatial map context or detailed model discussion as some competitors, and a seven-day cell should never be read as a firm appointment with clear sky. Conditions close to departure matter most. The website and free mobile apps suit observers who want a repeatable daily check, while embeddable forecast images are convenient for clubs and observatories. Pair it with satellite imagery or a second model before a long drive to a dark site.
