Why did radar service disappear?

Hello anatoliy98,

This page can help out with noting the various features the Weather app will offer: Check the weather on iPhone - Apple Support

When you open Weather, the details for your current location are shown. If you don’t see them, tap , then tap My Location.

Scroll down to view weather details such as:

•Hourly forecast: Swipe the hourly display left or right.

•10-day forecast: View weather conditions, chance of precipitation, and high and low temperatures for the coming days.

Tip: Tap a day in the 10-day forecast to see that day’s hourly temperature forecast, high and low temperatures, and more. Tap  to change the displayed weather condition.

•Severe weather alerts: View updates for weather events such as winter storms and flash floods (not available in all countries or regions). Tap the alert to read the full government-issued alert.

•Air quality: View air quality information; tap to view details about health information and pollutants (not available in all countries or regions).

Note: The air quality scale appears above the hourly forecast when air quality reaches a particular level for that location. For some locations, the air quality scale always appears above the hourly forecast.

•Maps: View a map of temperature, precipitation, or air quality in the area. Tap the map to view it in full screen or to change the map view between temperature, precipitation, and air quality. See View weather maps on iPhone.

Additional details: Scroll down to see additional weather information such as the UV index, sunrise, sunset, wind, precipitation, and more. Tap a weather detail for the extended forecast, daily summary, and data specific to that detail.

Tip: Some weather details include interactive features; drag your finger over the chart to see data values at specific times, tap a day to see data values for that day, or tap  to switch the view to a different weather detail.

If you find that there's something you'd like to see changed or improved you may opt to leave feedback for Apple. The best place to provide feedback will be on the dedicated feedback site here: Product Feedback - Apple

Cheers.
