Forecast Bar opens up on iPhone Duo

iPhone Duo gives the forecast room, and Forecast Bar now uses all of it. Open it and hold it on its side, and your conditions and your forecast sit in two even columns either side of the fold, running to the bottom of the screen with more of your background in view.

Half-folded like a book, the columns part to clear the crease. Half-folded upright, Weather Details sits above the fold, with today and the days ahead below it. Tap any day and it opens in Weather Details beside your forecast.

Close your iPhone Duo and stand it on its side, and it becomes a small weather display. The time and the weather now are large enough to read from across the room, with a temperature curve for the hours ahead. Stand it upright again and the app is back as you left it.

Locations on iPhone Duo and iPad is a gallery now. Every place gets a card with its own scene, temperature and local time, so a list of cities reads like a look out of each window.

Search for a place, set Home, rename it, or hold a card and drag it where you want it. Search can also show you somewhere without adding it to your favorites.

Settings on iPad now uses two columns, and it has its own button in the bar. The compare screens show the current numbers beside the charts.

Upcoming Travel no longer needs your calendar. Add a trip by hand with a place and the first and last day, which suits travel that isn't on your calendar, or keeping an eye on where someone in your family is going. Turn Find Trips in Calendar off and the calendar is never read or asked for. Your trips sync across your devices, and Upcoming Travel is on the Mac in this release too.

Add as Trip works in the Locations gallery too. On iPad and iPhone Duo, search for a place, turn on Add as Trip, pick it, and choose your days.

An hourly chart can now show up to three data points at once, like Temperature with Dew Point and Humidity. Each line gets its own color, and a data point with different units gets its own scale on the left. Your choices sync across your devices.

Next Rain answers the question the hourly forecast can't: when is it next going to rain or snow, even if that's days away? It's a new widget with your backgrounds and icons, on the Lock Screen, and an Apple Watch complication. Apple Watch also gets two new corners, Big Temperature and Big Temperature + Range.

Radar Layers shows every layer as a picture of what it draws, so you can see the difference between them before you choose.

Overlays work the same way, with a tile for warnings, lightning, storm cells, storm reports, rain gauges and outlooks. A View saves a whole set so you can switch to it in one tap.

Temperature, Feels Like, Dew Point and Wind run on new high-resolution forecast maps, from 6 hours ago to 18 hours ahead, and every map layer now plays smoothly from frame to frame. Outside the US they use the best forecast model for your region: HRDPS in Canada, ICON-EU in Europe, and ECMWF everywhere else.

Wind now draws animated flow lines, and it goes up. Winds aloft run from 5,000 to 34,000 ft. The colors are calmer too, saving the warm ones for gusty days.

U.S. Satellite now shows our own GOES imagery. Clouds drift smoothly between scans, visible-light clouds appear by day, and a Storm Tops style shows what's building.

Wildfire Smoke plays hour by hour, from 12 hours back to 18 hours ahead, and clean air stays clear.

Temperature Change shows the last 24 hours: blue where it's colder, red where it's warmer, from 12 hours back to 18 hours ahead.

Precip Type is now Smooth Radar colored by rain, snow, ice and freezing rain, with the same smooth motion, forecast and scrubbing. Smooth Radar is the only radar now, and a seamless nowcast fills the gap between the newest scan and the forecast.

The picture grids and the new maps come to the Mac, and Settings and Compare use the extra room in wide windows.

Every radar layer is now on Apple TV: road conditions, road cameras with live video, rain gauges and outlooks, with a Nearby panel of what's in view. Press, hold or swipe on the remote to glide the radar through time.
