FAQs on the Tempest System Forecasts
- Where does the Forecast come from?
The forecast data displayed in the Tempest app is produced by WeatherFlow. Our modeling systems start with data from a variety of third-party sources, including global and regional numerical models from US and European weather agencies, as well as WeatherFlow’s in house regional numerical models. The forecasts are then enhanced using the rich source of WeatherFlow observations in WeatherFlow’s proprietary machine learning (AI) forecasting platform to improve the forecast for your specific location.
- How is Tempest's forecast better than others?
Improvements are made to the local forecast as the machine learning (AI) ingests observations from your Tempest System and other observations in your area. We pay a great deal of attention to the quality of the observations coming from your Tempest and our Continuous Learning AI seeks to improve the quality of your unique observations. You will notice advantages in accuracy over other forecasts starting about ~60 days from the time of installation. You may notice additional improvements going forward as we learn more about your local weather.
- Why does the daily probability of precipitation not match the hourly values?
The probability of seeing precipitation at any hour during the day will always be greater than the probability of seeing precipitation within one hour of that day. It's a little like the fact that the probability of an individual coin toss is 50% heads, yet the probability of getting at least one heads in 5 throws is almost 97%. The actual values presented are derived from the complex interplay of math, physics, meteorology and magic that happens in the WeatherFlow data science center.
