When you see eg 0307 that means between 0300 and 0700, it then moves to
0710. Again 0700 until 1000 etc. So the bits in between each time frame are the predictions.
PROB30 means might happen, but probably not, good to cover bases.
PROB40 more than likely will happen.
So the TAF at the bottom decodes:- Produced 24th at 2110z for the 24th between the times 2200 and 0700 wind VRB05KTS CAVOK BECOMING between 0100 and 0400 7km vis
Hope that helps.
