Most weather apps give you a single number and call it a forecast. LucidSky shows you where forecasts are confident and where they're not, built on National Weather Service (NWS) data with ECMWF, GFS, HRRR, and ICON model comparison. A free Dark Sky alternative for people who want to understand the weather, not just glance at it. See what meteorologists actually see. Weather forecasts are inherently uncertain, but most apps hide that behind a single number. LucidSky doesn't. Choose Honest Mode to see confidence ranges around every prediction, or stick with Classic Mode for a clean, traditional experience. Same data, more transparency. Looking for a Dark Sky, AccuWeather, or Apple Weather alternative?
