Try to find something broadcasted/recorded that also has a transcript. Take the transcript and completely translate it, or at least, look up every unknown word and difficult/unfamiliar phrase.
Now listen to the broadcast/recording and experience hearing what you are expecting to hear. The ability to listen comes from an understanding of expectation of what you will hear. Since we are not native, we don't have any pre-concluded expectation, and so, we mis hear everything, until we are so familiar with phrases and vocabulary that we can predict the next word in a sentence.
The only way to do that is by translating and then listening. For my personal experience, I translate the sermon at our Korean church each Friday (or Saturday if I'm behind). Then I listen via a headset and verbally translate while reading my fully written translation. My ability to understand the vocabulary and phrases of sermons has catapulted into a new arena.
If you want to be able to understand the News or Weather broadcasts, translate them. Get used to the sequeways and types of phrases. With weather less so, but with News the vocabulary will always be expanding, so while that is problematic, if you are translating and then listening to a particular type of speaking, you will get better at it through this method.
