Abrupt Weather changes still evident (Latest 40th Anniversary Update)

Had abrupt weather state update yesterday using live time & weather - MSFS 1.33.8.0 - was flying glider over central europe when after about 40 min in flight all surrounding clouds changed with added heavy rain near me.
I’ve got good internet connection - no warnings etc.
Expected that any weather updates would be gradual not in split second - especially important and immersion breaking when flying gliders whose fuel is weather.
