Why does the forecast change so frequently?
Quick Answer: Weather forecasts change frequently because the atmosphere is always shifting. New data comes in constantly, and models update to reflect those changes. This helps give you the most accurate prediction possible.
Weather is super dynamic. Tiny shifts in temperature, wind, or humidity can change how storms or rain develop. Forecasters use powerful computer models that run many simulations with the latest observations. As new info arrives, these models adjust the forecast.
Also, different models may predict slightly different outcomes, and forecasters blend these together. This means your forecast can look different hour by hour or day by day. It’s all about tracking a moving target as closely as possible.
