`GET /weather/historical/actuals/daily/{format}`

The `Get Daily Historical Actuals` API is an HTTP `GET` request that returns
climatology data such as past daily actual observed temperatures,
precipitation, snowfall, snow depth and cooling/heating degree day information,
for the day at a given coordinate location. The data is requested for a
specified date range, up to 31 days in a single API request. Generally,
historical data may be available as far back as the last 5 to 40+ years,
depending on the location.
