Weather Report Generator for Radio Station

This Python program fetches weather data from Weather.com, generates a speech-based weather report, and outputs it as an MP3 file with background music for radio stations. The report includes current weather, an 8-hour forecast in 2-hour increments, and a 3-day forecast.

Sample

weather_update.mp4

Features

• Fetches current, hourly, and daily weather data from Weather.com API.
• Generates a detailed weather report with temperature, conditions, and forecasts.
• Converts the weather report text into speech using Google Cloud Text-to-Speech API.
• Adds background music with fade-in and fade-out effects to the speech audio.
• Outputs the final weather report as an MP3 file with metadata tags.

Requirements

• Python 3.7 or higher
• requests library
• google-cloud-texttospeech library
• pydub library
• mutagen library

Setup

Step 1: Google Cloud Service Account Key

To use the Google Cloud Text-to-Speech API, you need to create a Google Cloud service account and download a JSON key.

1. Go to the Google Cloud Console.
2. Create a new project or select an existing one.
3. Navigate to IAM & Admin > Service Accounts.
4. Click Create Service Account.
5. Enter a name for the service account and click Create.
6. Grant the service account Editor permissions.
7. Under Keys, click Add Key > Create new key and select JSON.
8. Download the JSON key file.
9. Save the file to a folder called /etc/radio_weather_report/

Place this file in a secure location, and set the GOOGLE_APPLICATION_CREDENTIALS environment variable to the path of this file in your system.

Step 2: Weather.com API Key

To fetch weather data, you need to obtain a Weather.com API key.

1. Open wunderground.com (Wunderground is owned by Weather.com).
2. Right-click on the page and select View Page Source.
3. Search for "apiKey" in the source code.
4. Copy the value of the API key.

Step 3: Install Dependencies

Install the required Python libraries:

• requests
• google-cloud-texttospeech
• pydub
• mutagen

Step 4: Setup Your Cron Job

To run the weather report generation script automatically, you can create a cron job.

1. Open your crontab file by running:

   crontab -e

2. Add the following line to run the script every hour on the half hour:

   5 * * * * /usr/bin/python3 /path/to/weather.py >> /path/for/log/weather.log 2>&1

This cron job will execute the script every hour at minute 5, logging output to /path/for/log/weather.log.

Step 5: Customize Script Variables

In the script, make sure to customize the following variables:

• output_file: The path where the weather report MP3 file will be saved.
• radio_station: The name of your radio station.
• weather_report_name: The name you want for the weather report.
• WEATHER_API_KEY: The key you retrieved from wunderground.com
• LATITUDE = Latitude for Radio Station
• LONGITUDE = Longitude for Radio Station

Step 6: Add music

1. Pick a royalty-free background music track. You can find suitable music on sites like YouTube Audio Library, Free Music Archive, or Incompetech.
2. Download file to /etc/radio_weather_report as music.mp3

Step 7: Run the Script

Run the script manually to generate a weather report.

The script will fetch weather data, generate the weather report, convert it to speech, and output the report as an MP3 file with background music.
