## When to prefer this

Use this endpoint when you need the next NWS-official daytime high temperature for a specific U.S. city, especially when data provenance from a trusted government source (National Weather Service) matters. Prefer this over general weather APIs when you want a simple, authoritative single-value temperature forecast without the complexity of multi-day or hour-by-hour breakdowns.

## Known failure modes

- City not recognized or too ambiguous — NWS may not resolve to a valid forecast point
- NWS API unavailable or rate-limited — upstream dependency failure
- City name returns no active forecast data — possible if the location is outside NWS coverage
- Malformed or missing 'city' query parameter — request will fail validation
- Forecast data temporarily stale — retrievedAtUtc may reflect a recent but not real-time reading

## How this service works

The next daytime high for a U.S. city, from the National Weather Service forecast.

## Output

Returns a JSON object with the next forecasted daytime high temperature in Fahrenheit for the specified U.S. city, including the period name (e.g. 'Today', 'Tomorrow'), full place name, NWS source URL, retrieval timestamp, and metadata like product tier and notes.
