In my partly cloudy= "djelomično oblačno" , language there is not enough space to display both words. I marked that in the picture.
I will show in the next picture that the forecast from the plugin and that forecast in the secondary infobar do not match in the description of the forecast. I don't know if you understand me. I will try to explain: today is Friday, and the forecast for today is partly cloudy, and that forecast is correct - the description and icon of the forecast match. Tomorrow is Saturday - the plugin shows rain - the icon and description show rain. In the secondary infobar, the icon shows the exact time, but the weather description is from Friday (partly cloudy). I don't know if it's clearer to you now.
Do you mean thqt weather description is for the previous day ?
I have adjusted the English language so that you can understand more easily. As you can see, the weather description is the same for today and tomorrow. Today it is mostly cloudy, as shown by the icon. For tomorrow, it says mostly cloudy, and the icon shows rain. Plugin shows rain for tomorrow.
