current Current weather data API response
current.dt Current time, Unix, UTC
current.sunrise Sunrise time, Unix, UTC. For polar areas in midnight sun and polar night periods this parameter is not returned in the response
current.sunset Sunset time, Unix, UTC. For polar areas in midnight sun and polar night periods this parameter is not returned in the response
current.temp Temperature. Units - default: kelvin, metric: Celsius, imperial: Fahrenheit. How to change units used
current.feels_like Temperature. This temperature parameter accounts for the human perception of weather. Units – default: kelvin, metric: Celsius, imperial: Fahrenheit.
current.pressure Atmospheric pressure on the sea level, hPa
current.humidity Humidity, percentage
current.dew_point Atmospheric temperature (varying according to pressure and humidity) below which water droplets begin to condense and dew can form. Units – default: kelvin, metric: Celsius, imperial: Fahrenheit
current.clouds Cloudiness, percentage
current.uvi Current UV index.
current.visibility Average visibility, metres. The maximum value of the visibility is 10 km
current.wind_speed Wind speed. Wind speed. Units – default: metre/sec, metric: metre/sec, imperial: miles/hour. How to change units used
current.wind_gust (where available) Wind gust. Units – default: metre/sec, metric: metre/sec, imperial: miles/hour. How to change units used
current.wind_deg Wind direction, degrees (meteorological)

Summarize hourly weather until midnight today. Keep it concise. Suggest how to deal with the weather, such as how to dress for the weather, and whether they need an umbrella.
Use celsius and fahrenheit but not Kelvin for temperature. Mention %v in the summary, but don't add anything else, as the summary will be displayed on a website.
The summary should be in plaintext for humans. Do not output in JSON.
