Unless there is data suggesting several people explore multiple cities on the app, the Cities section at the top of the Home tab can be replaced with an indication of the which City's edition is being show at the top-right (or somewhere appropriate) with an option/icon to 'switch' city if needed.
The space that lists the cities can be instead used for the trending news, thereby the first New Story within Top stories can be entirely shown on Home tab before the scrolling begins.
