Ensemble Weather

Ensemble Weather doesn't show you one forecast – it shows you all 51.

Classic weather apps display a single, seemingly precise number – "24° tomorrow". Ensemble Weather instead uses the ECMWF ensemble (IFS, 0.25° resolution): 51 equally valid model runs that reveal how certain or uncertain the forecast really is.

WHAT MAKES THIS APP DIFFERENT
• Temperature as an honest range (e.g. 24° ±3°) instead of false precision – the range is the actual spread across the 51 model runs
• Rain probability = the share of model runs that actually compute rain
• Thunderstorm risk (⚡ to ⚡⚡⚡) from real CAPE values, not just the weather code
• Visual warnings for thunderstorms, heavy precipitation, and storm gusts

FEATURES
• Forecast for your current location – the model is global, so it works anywhere on earth
• Add any number of extra locations, swipeable as pages, each in its own time zone
• Hourly forecast (48 h) and a 15-day overview
• Home screen widget with current conditions
• The app icon adapts to the current weather at your location
• Light and dark theme

PRIVACY
• No ads, no tracking, no account
• No backend server – data goes straight from Open-Meteo to your device
• Only the coarse location permission, and even that is optional: manually added locations work without it

Recent changes:
Temperatures are now colored using NOAA's official color scale (blue = cold to red = hot), with better-readable text in light mode too.
Fixed a bug where yesterday could briefly reappear as its own card right after "Today" on the GPS tab.
Temperature display is a bit bigger everywhere.
New: tap any day card to see the full 24-hour forecast for that day.
