Overview
- Forecast accuracy in smartphone apps falls sharply after day 7 as icons default to statistical trends rather than model calculations.
- Short-term rain radar delivers reliable minute-to-hour predictions but extrapolated start times can change if showers alter course.
- Pinpoint forecasts for individual districts derive from weather models with multi-kilometer grid resolutions that often miss local variations.
- Rain-probability percentages reflect the frequency of rain in similar conditions instead of indicating how long it will rain.
- Users should combine radar imagery with probability data, compare multiple forecasts and maintain flexibility for events beyond a week.
