In the future, it will have a pill-shaped container where the weather will be highlighted in a pie form with a color accent. There will also be a 3-dot button on the widget to bring up a context menu. Presumably, it will call the bottom sheet shown in the second picture, which also mentions the widget style change (I posted this a week ago on my Twitter).
It looks like Google has decided to revamp the current outdated At a glance. However, I can’t demonstrate how it works as it’s not yet functional.
Keep in mind that this does not apply to the At a Glance (aka Smartspace) widget built into the Pixel Launcher.
