Thurs 23, says 0% chance of 5.5 ml of rain …
I realise that forecasts are only a ‘best guess’ and can change at any time, but this seems to me on of the weirder ones, would love to know if there is an explanation

Hi Anne, our rainfall data each day in the daily totals is actually broken into two segments: Daytime and nightime. So if you see that it means rainfall will be occuring overnight. If you use the rain graphs at RuralWeather.co.nz or in the WeatherWatch App you will be able to make more sense of it.
Kind regards
– WW
