Google has made a back-end change to the way it is delivering weather cards. Rather than displaying stacked cards for nearby cities, a single cards with multiple lines will now display the weather information of nearby cities in a region. The update, which is handled on the server side, doesn't require an update to the Google Search application so user intervention isn't required.
With a single card displaying weather information for multiple cities, tapping on a city would take you to a more detailed multi-day weather forecast for that city.
This update joins a series of recent Google Now improvements over the last few days, including better rental car information as well as the ability to set timers and reminders using solely your voice.
The update should be rolling out now to users.
