What is the normal prediction period for local weather forecasts?

The normal prediction period for local weather forecasts is typically around 24 to 48 hours. In practice, forecasts are known to provide the most accurate information within this timeframe due to the reliable models and data available for shorter-term conditions.

Choosing 36 hours as the prediction period reflects a common understanding of when weather conditions can be reasonably anticipated with high confidence. Forecasts beyond 48 hours begin to incorporate more uncertainty as they rely on changing atmospheric conditions, making it more difficult to predict specific weather events accurately. However, for the most reliable and immediate forecast, the range of 24 to 48 hours is generally the standard.
