No mention of a possible shower in the far south from any other source. Looking back to the 14th and the seven day rain maps for down here, they were way off!

Were NIWA and MetService more accurate?

NIWA are abysmal for their ‘forecast’ temps down here so I take any projected rainfall from them with a grain of sale and as for Metservice, their extended computer models always shows showers or rain. And I’ve noticed with Metservice, is that it’s more likely to be called ‘occasional rain’ in the south and ‘occasional showers’ for the north.

Will have to work on improving this. Southland is a very large region with a lot of fine details to forecasting, it’s perhaps one of the trickiest regions to accurately cover from one side to the other. In saying that, loads of places on earth are tricky so it’s not really an excuse that stands up forever. A work in progress LM.
