Tempest Forecasting

How It Works

Weather observations stream instantly from the solar-powered, wireless Tempest station through WeatherFlow’s data processing center. Tempest performs quality control inspections on raw station sensor data, and may apply calibration corrections as needed.

All About the Data

Accurate measurements from your location, along with data from other Tempest Systems combine with ALL other relevant weather data, including measurements from satellites, aircraft, radars, and other surface weather stations. Our process ultimately yields standardized data and a real-time analysis product. Not every measurement is of equal value (e.g. wind ‘shadows’ affect how wind data is utilized) but our big data analytics adjust accordingly, meaning every Tempest System can make a difference.

Your Better Forecast

Under the watch of WeatherFlow’s team of meteorologists and data scientists, our forecast system initializes with the ECMWF, the highly acclaimed European global forecast model and the best of NOAA’s forecast models. Over key areas, WeatherFlow’s operational forecast system (WF WRF) assimilates the most valuable observations into this powerful baseline to provide detailed regional forecasts. We then apply powerful machine learning techniques (WF AI) to post-process the model output, providing a more accurate regional forecast than can be produced by models alone. To personalize your forecast we use additional AI based on data from your Tempest.

A Better Weather App

What makes this your new favorite weather app?
  1. Easily integrate with popular smart home services using your weather data to optimize heating and cooling, adjust your irrigation schedule, alert your family when lightning storms approach or close your garage door when the wind picks up.
  2. Enjoy more than 15 weather measurements, including temperature, lightning activity, UV index, and wind speed.
  3. View, share, and export historical climate data through customizable graphs and charts for precise weather monitoring.
  4. Your forecast starts out great and gets even better over time.

WeatherFlow guarantees the Tempest System will produce a better forecast for the specific location in which it is installed. If you believe the forecast provided by your Tempest System is not measurably superior to forecasts publicly available elsewhere, you may request a full refund for the Tempest System up to 8 months after the date of purchase.
