SW Feature idea: weather shows cached data if offline or not connected

Software Feature idea:

If there is no connection to the phone, or bad connection from the phone to the internet, the native weather app shows: „waiting for data“ or „phone connection required“

would it be possible to cache the data with a time stamp and show it 

so for example/: the weather data is 2 days old, but still shows the two days left from forecast

would be amazing if you are out with the watch alone, or if there is no connection or no internet available.
