12-hr radar is back. Future radar now uses NOAA's HRRR forecast model, so you can scrub the next 12 hours of rain and storms anywhere in the continental US. Outside the US, the Radar tab tells you it's US-only instead of showing a blank map.
Undo for deleted cities. Swipe a saved city away by mistake? Tap Undo to bring it right back.
Location off? Today still works. Pick a saved city or tap Search for a city.
Larger text no longer cuts off Feels like, High and Low on Today.
Tap the radar map on Today to jump straight to the Radar tab.
Sky Check answers stream in more smoothly.
Alerts outside the US explain what's covered instead of pointing you to the National Weather Service.
With Reduce Motion on, 12-hr radar waits for you to press Play. VoiceOver now announces the selected tab and radar mode.
The lightning layer is paused while we line up a new data source.
