After the rain is gone...

Back home, in Cambodia, there's always sunshine after the rain is gone (of course, in daytime). And we use there's always sunshine after the rain is gone to mean everything is gonna be fine to cheer people up when they are upset or have problems but here, in New Zealand, it is so not applicable because the sky is still gloomy after raining. Or it tells us that after one problem there's another one to come right after?
