Conclusion

The analysis of rainfall predictions for 2024-2025 reveals several key insights. Rainfall distribution is relatively consistent across the United States, with some variability driven by location-specific climate factors, such as those influencing cloud cover and temperature. While cloud cover shows a stronger correlation with rainfall, wind speed appears to have minimal impact. Additionally, temperature variations between 2024 and 2025 highlight regional differences that may affect future weather patterns. Overall, while the predictive models provide moderate accuracy, further analysis and more advanced statistical approaches will be needed to refine these predictions and better anticipate future rainfall trends.
