The $twcweather system variable provides data from The Weather Company following the shutdown of the Weather Underground API that powered $weather. $twcweather was introduced in webCoRE v0.3.10a.20190223. See sample data below which is available for webCoRE installs running on the SmartThings platform.

Partial day forecast

The forecast includes morning and evening data for various attributes. The indexes begin at 0 for "this morning" so 2 is tomorrow morning and 3 is tomorrow evening (see the daypartName value). To show an icon for tonight's weather you would get the icon code with the expression $twcweather.forecast.daypart[0].iconCode[1]

Note that the first value for some attributes may be blank in the evening. For example, running a piston in the morning you may get $twcweather.forecast.daypart[0].cloudCover => [ 25, 79, 100, ...] but that same evening $twcweather.forecast.daypart[0].cloudCover => [ null, 79, 100, ...].

Preliminary testing shows that today's morning/daytime data [0] turns null shortly after 3PM each day, and the next day's data shifts to [0] and [1] shortly after 3AM. This means from approximately 3PM to 3AM, you will find [0] to be null, and [1] will show data from the evening/night in progress. This also means that at about 3AM, the data for the night in progress vanishes, and is replaced with data for the following day/night.

Here's my findings over 20 days/40 events: … (Graph shown here) 
* 22 changed between 2:58 and 3:10   (55% of the time)
* 10 changed between 3:10 and 3:20   (25% of the time)
*  8 changed between 3:20 and 3:36   (20% of the time)

Old icon sets

Several additional icon sets are available but all have a much more limited set of icons. We have ensured that the $twcWeather icon code numbers map to an approximately accurate representation in the old icon sets. While the old sets work we encourage use of the more expressive TWC and WU v4 icon sets.

All of the icon sets described on the original Weather Icons page work with the new codes, for example :wu-b-36: maps to the "sunny" icon in the "B" icon set.
