Observations build the starting picture
Weather stations, satellites, radar, aircraft, ocean buoys, and other systems observe temperature, pressure, wind, clouds, and precipitation. These observations help describe current conditions.
Models project forward
Numerical weather models use physics and observations to estimate future atmospheric conditions on a grid. Forecasters and weather services compare model guidance with new observations and local knowledge.
What Weather Chase displays
Weather Chase receives forecast information through its configured Open-Meteo weather data service and presents it as current conditions, hourly forecasts, daily outlooks, and related weather details. Weather Chase does not own the satellites or models.
What this means for your day
A forecast is a reasoned estimate based on observations and models. It becomes less certain as the forecast period gets farther away.
Frequently asked questions
Why does weather forecasts change?
Weather information updates as new observations and forecast model runs become available. Small changes are normal, especially farther into the future.
Where can I see this information?
Use Weather Chase's current conditions, hourly forecast, daily forecast, and map tools to compare the latest information for a location.
