WorstForecast Data Response

This object represents the "worst" hourly forecast found within a larger ForecastMatrix based upon the time and distance parameters provided in the query. The response provided will be similar to (but a subset of) the SingleForecast response. No DailyForecast objects will be returned and only a single HourlyForecast will be returned, representing the "worst" forecast found. Output is available in either imperial or metric units.

Severe weather alerts will be returned as normal, although their start/expiration time may not include the time of the "worst" forecast selected.
