Description of problem:
When combining the hourly-weather-card with other cards using the popular vertical-stack-in-a-card card, the outline does not vanish. I am reporting this here and not in the issues for the vertical-stack-in-a-card GitHub, as I do not experience this issue with any other card and think it must be related to the way the border is implemented in the hourly weather card.

It would be great it you could look into this. I'd love to implement your innovative weather bar into an overview which combines the issues of several weather apps in one visual card.

I'm having the same problem with vertical-stack-in-card too.
In addition, it shows as 'Sunny' all night e.g. until 2am for some reason, but not sure if that's related to this issue

I was able to mitigate this issue using card-mod to make the boarder of the individual card 100% transparent. This isn't letting me format it with the correct indentation for the yaml, so make sure you do that if you try this.
card_mod: style: | ha-card { --ha-card-border-color: rgba(255, 255, 255, 0); --ha-card-background: rgba(255, 255, 255, 0); }

FWIW that card-mod workaround did not work for me, i still have the problem with the border of this card.
...and this is the only card in the vertical-stack-in-card that i can't remove the border
