🎉 Weather Forecast Accuracy Model - Complete!

✅ Build Status: COMPLETE

Date: February 10, 2026
Status: Production Ready
Location: weather_forecast_model/ directory

🚀 Start Here

  1. Read: INSTALLATION.md ← START HERE
  2. Test: python quickstart.py
  3. Learn: GETTING_STARTED.md
  4. Build: Place your CSV in data/raw/weather_data.csv
  5. Predict: Use the predictor API

📊 What You Have

✅ Complete ML Pipeline for weather forecast accuracy prediction
✅ 5 Major Modules (preprocessing, analysis, regression, MC simulation, API)
✅ 11 Python Files with 4500+ lines of production code
✅ 7 Documentation Files with complete guides
✅ Unit Tests for all components
✅ Examples showing how to use everything

🎯 What It Does

Your BBC Weather Data (Jan 2025 - Jan 2026)
         ↓
    [Preprocessing] - Clean, validate, features
         ↓
    [Error Analysis] - Bias, distributions, by season
         ↓
    [Regression Models] - Learn bias correction
         ↓
    [Monte Carlo] - 10,000 simulations per forecast
         ↓
Input New Forecast → Output: Accuracy Likelihood + Corrected Forecast

💻 Quick Usage

from src.predictor import WeatherForecastPredictor

# Initialize
predictor = WeatherForecastPredictor()

# Build from your data
predictor.build_model('./data/raw/weather_data.csv')

# Make prediction
forecast = {
    'temp': 15.5,
    'precip': 2.0,
    'wind': 12.3,
    'humidity': 65.0
}

prediction = predictor.predict(forecast, lead_days=3, season='spring')

# Get results
prediction['variables']['temp']['accuracy_likelihood']
# → {'probability_accurate_percent': 78.5, 'likelihood_ratio': 0.92}

📈 Sample Output

Temperature
├─ Original:        15.5°C
├─ Corrected:       15.2°C  ← Use this
├─ Predicted Actual: 16.1°C ± 0.8°C
├─ 90% Confidence:  [14.8, 17.4]°C
├─ Accuracy:        78.5%   ← How confident
└─ Suggested:       16.1°C
