This sounds like the Google Now feature. If you have chrome installed and running, you can click the alarm-bell-like icon in your menu bar to configure it.

How Google Now works in Chrome
If you use Google Now on your mobile device, you can see certain Now
cards on your desktop computer if you're signed into Chrome, including
weather, sports scores, commute traffic, and event reminders cards.
Some of these cards may be based on the location of your mobile
device. Learn how to sign into Chrome
To see these cards, open the Chrome Notifications Center by clicking
the bell icon in the system tray on the lower right corner of your
computer screen (on Windows) or in the menu bar on the upper right of
your computer screen (on Mac).
Below is a screen shot showing where the bell is on my menubar (YMMV).
