feature: show weather

[eklem]

Met.no has changed their format from JSON to XML, so need to convert it. This library may work: xmlToJSON?

So, use fetch() to get the XML, covert it to JSON and store as a Vue data object and display what I need.

Need longtitude and latitude for Vålerenga.

Explanation on what is light rain, rain and heavy rain: https://hjelp.yr.no/hc/no/articles/115003696813-Hva-er-grensene-for-lett-og-kraftig-nedb%C3%B8r-

So, previous URL for 6 hour blocks forecast and thus one for rain next 90 minutes: https://api.met.no/weatherapi/nowcast/0.9/documentation

[eklem]

The yr.no API for 6 hours seems easier to use. More direct connection to weather icons. https://www.yr.no/sted/Norge/Oslo/Oslo/Oslo/forecast.xml

I may get some explanation to when to show a sleet symbol from Yr.no on Twitter.

[eklem]

So, to sum it up so far:

• Skip sleet calculation for now
• Below zero degrees celsius = snow
• Zero degrees celsius and above = rain
• Show weather for the 6 6-hour blocks closest to now.
• Show precipitation for the next 90 minutes.
• Use Matmonsen's weather icon font to display weather forcast.
• Use metatribal's xmlToJSON to transform input to JSON.
• Use Sunrinse API to check when sun rises and sets.

[eklem]

Try D3.js for drawing possibility of rain or snow next 90 minutes. Or maybe Vega? Seems no real real programming needed.

Seems there is now a JSON api (version 2.0): https://api.met.no/weatherapi/locationforecast/2.0/?lat=60.10&lon=9.58

• No need to check for sunrise or sunset, just convert weather icons to icon html names.
• Filter on 6 hour blocks and output as html.
