Will it Rain? Multi Forecasts

Will it Rain? asks 4 different weather forecast models the same question about your city — and shows you what most of them agree on.

Instead of trusting a single forecast source, this app queries four independent weather models, each built by a different meteorological organization using different methodologies:

• GFS (Global Forecast System) — by NOAA, United States
• ECMWF (European Centre for Medium-Range Weather Forecasts) — European Union
• ICON — by DWD, Germany's national weather service
• wttr.in — an independent weather service

Each model analyzes atmospheric data differently. When 3 out of 4 agree it will rain, you can feel pretty confident about grabbing that umbrella.

HOW IT WORKS

1. Search for any city in the world
2. The app fetches forecasts from all 4 sources simultaneously
3. For each period of the day (Morning, Afternoon, Night), it shows what percentage of models agree on each weather condition
4. A clear majority (75%+) is highlighted prominently, so you can see the consensus at a glance

WHY MULTIPLE SOURCES?

No single weather model is always right. Different models excel in different regions and weather patterns. By showing the consensus, Will it Rain? gives you a more reliable picture than any single app could.

Think of it like asking 4 different meteorologists: if most of them agree, you can be more confident in the forecast.
