# How to Get Event Weather Forecasts with ChatGPT

ChatGPT turns weather forecasts into practical event planning advice anyone can act on. It fetches the detailed forecast for your venue and date, recommends whether to prepare a rain plan, suggests the best time windows for outdoor activities, and can draft the weather advisory you would send to attendees or staff.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Configure ToolRouter in ChatGPT
2. Ask: "What will the weather be like in Chicago on June 15th?"
3. ChatGPT returns a detailed forecast with conditions throughout the day
4. Request: "Should I plan for indoor backup based on this forecast?"

## Example Prompt

```
I am planning a corporate picnic in Central Park next Friday. What does the weather look like? Should I have a rain plan?
```

## Tips

- ChatGPT can recommend optimal time windows based on the forecast
- Ask for clothing recommendations to include in event invitations
- Great for creating weather briefings to share with event teams
